[PRIOR ART] The present invention relates to an absorbent structure, such as a personal care product, more specifically an absorbent article having an absorbent body. Part of the stable non-woven absorbent structure. Absorbent articles are widely used in personal care products, such as diapers, children ’s toilet training pants, adult incontinence clothing, medical clothing, sanitary napkins, etc., and surgical Use end straps and sea han. These objects can absorb and contain the peritoneal waste, and they are all disposable and will be used after a limited time «, It means that the mixed age will not be taken away by the thief for recovery. The traditional disposable absorbent article will contain an absorbent body, which is located on the lining in contact with the wearer's skin and prevents the carcass excretion absorbed by the absorbent body from leaking out. Between the outer cover of the article. The lining of the absorbent article is often liquid permeable, through which the material can be absorbed by the absorbent body.-General shaped fiber fabric used as an absorbent body for such absorbent objects (Usually referred to as air forming), separated fibers such as cellulose or other suitable absorbent fibers and particles or fiber superabsorbent materials are introduced into the package. The absorbent and superabsorbent particles will Air flowing in an air forming device and being made-on a porous forming surface, a mixture of absorbent fibers and superabsorbent particles may be hidden on the forming surface and admired-absorbent fiber fabric or structure. Air used in high-speed commercial operations The forming device has a forming surface consisting of a cable screen or a scored grid, and _ or more forming members, these forming members E: \ PATENT \ PK-001 08 \ 083 1 \ pk-001-083I-I doc2003 / 6/13 564172 The boundary line screen or scoring grid usually defines the length 'width and thickness of the absorbent structure formed on the forming surface. Pneumatic mechanisms such as vacuum suction Systems that attract fibrous sludge with fibers from the air forming device to the forming surface and allow airflow to pass through the forming surface. Such systems have been applied to high-speed commercial operations. By using such air forming devices, the formed The absorbent structure has a basis weight (i.e., thickness) layer along its length and / or width, and also has a generally uneven width. © Iiqi formed absorbent structures containing absorbent fibers and superabsorbent materials have been proven for manufacturing The ideal shape and size of the absorbent body for various absorbent articles is very effective, and further improvements are also expected. More specifically, such structures will lack the integrity or stability of the original shape (i.e., length, width, and especially thickness) after the wearer has excreted the vegetative fluid multiple times. For this purpose 'it is known to use a conventional air-laying procedure to form a stable absorbent fabric or structure to which a bonding material has been added. Such bonding materials have been coated or adhesives, powders, nets and bonding fibers. Bonding fibers have included one or more of the following types of fibers: homogeneous monofilaments, heat-fusible fibers, melt-blown polypropylene fibers, and the like. _ In the conventional air-laying system, the connecting fiber system is mixed with the absorbent fiber and the superabsorbent material 2 and then the-hollowing system is used to attract _ to the forming surface, and this mixture is placed on the forming surface of the hole. Then, the structure generated on the forming surface is heated to activate the connection, wear, and '隹' to melt a part of the connection fibers and form an internal fiber connection with the absorption fiber, thereby generating a stable structure. However, ‘this __ line shows the margin will be limited by the length of the fiber that can effectively bind the ridge. When operating conventional systems, the length of the link fiber is typically 6 legs or less. If you use longer connecting fibers, it will lead to blockage of the distribution screen, uneven distribution of the fibers, and coagulation of the fibers. The problem is that the basis weight is not the same. This breath placement system also requires more energy. In order to improve the qualitative fabric structure, it is necessary to extend the heating 2 of the structure excessively to charge and heat the connecting fibers. For example, a typical heating time bank I to 8 is shifted through an air-linked system. In addition, it is also necessary to excessively extend the cooling time of the fiber fabric (e.g., winding storage in a bin) to generate and preserve the desired stable structure before further processing operations. Therefore, the traditional 2 air weaving system is no longer suitable for manufacturing mosquito-absorbent structures directly connected to high-power-consumption product-converting machines. Rather, if a stable absorbent structure is desired to make an absorbent body of an absorbent article ... the general method is to make a fabric wider than the required non-linear qualitative fabric, and wind and store the fabric for individual manufacture Used in the machine. A particular disadvantage of such methods is that conventional air-laying systems are limited in the size of the stable structures they are manufactured. More specifically, the stable structure formed by leaving the air placement system can have both a uniform width (such as a straight side edge) and a basis weight and thickness of a substantially uniform sentence. If you want an absorbent structure with a non-uniform width, such as an absorbent structure with a narrow chin area, you must unfold the stable fabric made previously and cut the edge of the object to provide the desired width. profile. In this way, the selection of the selected fabric section will waste the fabric amount excessively, and the manufacturing operation will be too complicated. In addition, the _ system requires excessive costs for the shipment, storage, and winding of confidential materials. In addition, if the weight or thickness is supplemented so that the absorbent structure has a target area for increasing the basis weight to increase the absorption capacity, it must be cut from the -stabilizing fabric-the smaller (financial) layer, and this smaller layer Overlapping on larger stable fabrics to increase the basis weight of the absorbent structure on the target area. This requires additional steps and even complicates the manufacturing operation.

[Embodiment] Please refer to the drawings, especially the first figure, which illustrates an absorbent article made according to the present invention, and the whole is denoted by reference number 21. An absorptive article as used herein refers to an article that secures or approaches the wearer's body (such as touching the body) to absorb and / or retain various wastes excreted from the body. Some absorbent articles, such as disposable absorbent articles, are discarded after a limited period of use, rather than washed or reconditioned for reuse. However, it is contemplated that the principles of the present invention may be applied to outer garments (including reusable outer garments) and other absorbent articles. For example, the principles of the present invention may be incorporated into child training pants and other baby and childcare products, medical outerwear, sanitary napkins and other female care products, and the like, as well as surgical bandages and gauze. The diaper (21) in the first figure is in an unfolded and flattened state to show a vertical axis X and a horizontal axis Y of the diaper. The diaper (21) usually includes a central absorbent assembly (23), which passes from the front area (25) (i.e., front shaw) of the diaper through a lower area (27) (i.e., central area) to the rear area (29) ( That is, the rear) central absorption assembly (23) is generally I-shaped, more specifically an hourglass, and has a display contour, laterally opposite side edges (31) and longitudinally opposite front and rear waist edges or ends, which are respectively (33) and (35). It should be understood, however, that the diaper (21) may have other shapes, such as rectangular or tau, without departing from the scope of the present invention. The side edge (31) of the diaper (21) extends longitudinally from the front area (25) through the sub-condylar area (27) to the rear area (29) to form laterally separated leg openings (37) of the diaper when worn (p. Three images). For example, the area (25) usually includes a central absorption assembly (23) through the lower abdomen region of the wearer; and the back region (29) usually includes a central absorption assembly through the lower rear region of the wearer. The lower crotch region (27) includes a portion passing from the front region (25) to the rear region (29) longitudinally through the wearer's crotch and interposed laterally between the wearer's legs. When worn on the wearer (picture 3), the diaper (21) further defines a central waist opening (43) and a leg opening (37). With particular reference to the second figure, the central absorbent assembly (23) of the diaper (21) includes an outer cover, generally indicated by (49), a bodyside liner (51) facing the outer cover, and an outer cover The absorbent body between the cover and the liner is generally indicated by (53). The outer cover (49) of the illustrated embodiment E: \ PATENT \ PK-001 08 \ 083 l \ pk-001 -0831 -1, doc2003 / 6 / l 3 11 564172 usually defines the length and width of the diaper. The absorbent body (M) has a width of less than its side and the outer cover (49) has a width such that the outer cover extends beyond the sides and ends of the absorbent body in both the longitudinal and transverse directions. The bodyside liner (51) expands substantially along with the outer cover, or it can be made larger than desired (which would therefore define the length and / or width of the diaper) or smaller than the area of the outer cover (49). In other words, the body side view (M) is ideally superimposed with the outer cover but does not need to co-extend with the outer cover.外 In one embodiment, the outer cover (49) is stretchable and may or may not be slightly elastic. More specifically, the 'outer cover (49) can be sufficiently extended so that once stretched below the weight of the absorbent body', the outer cover will not substantially retract toward its original position. However, it should be considered that the outer cover (49) may be non-stretching and still remain within the scope of the present invention. The outer cover (49) can provide ideal stretchability as well as liquid impermeability and breathability for multilayer laminate structures. For example, the outer covering (49) of the illustrated embodiment has a two-layer structure, which includes an outer layer made of a breathable material and an inner layer made of a liquid-impermeable material (5, the two layers are, e Appropriate laminated adhesives (59) are connected together. However, it should be understood that the outer cover (49) can also be constructed of a single layer of liquid-impermeable material, such as the one used to construct the inner layer (5? ) Materials to make thin membranes without departing from the scope of the present invention. The liquid-impermeable inner layer (57) of the outer cover (49) may be breathable (ie, "breathable,") or impermeable. The side view (51) is ideally compliant, soft, and does not cause irritation to the wearer's skin, and is used to help isolate the wearer's skin from the absorbent body). Liner 01) is more hydrophilic than absorbent, ( 53) Low so that the wearer can access a drier surface and have enough holes to allow liquid to pass through its thickness easily. A suitable bodyside liner (51) can be selected from various mesh materials, but ideally Xie Shao can be stretched in the _ direction (such as axial or transverse). In the embodiment, the plant side lining (51) is ideally stretchable. It is stretchable and can be extended along the outer cover to allow the diaper to fit the wearer. 'The foot-fixing sheet (65) (pictures 1 and 3) is fixed to the central absorbent assembly (23) in the rear area (μ). And laterally extend from the opposite side edge (31) of the assembly. The fixing piece (65) can be connected to the outer cover (49), the body side liner (51), between the outer cover and the liner, or other On the diaper (21) member. The foot-fixing sheet (65) may also be elastic or made of rubber. For example, the fixing sheet (still) may be an elastic material such as a neck-bonded laminate (NBL) or a stretch-bonded laminate Material (SBL).

Alternatively, the solid sheet (65) may It is formed integrally with the diaper member selected by the body corpse. For example, the fixing piece ⑽ may be integrally formed with the inner or outer layer (57, 55) of the outer cover (49), or integrally formed with the body-side lining 定. Fishing ring fixtures, which are represented by (71) and (72) respectively, are used to ensure that the diaper (21) is worn on a child or other wearer. Alternatively, other fixing members (not shown), such as a button, a pin, a devil's stick, an adhesive tape fixing, an adhesive, a mushroom ring fixing, etc. can be used. Ideally, the interconnection of the 'foot-fixing members (71, 72) is selectively unlatched and re-fastened. In the illustrated embodiment, the hook fastener (40) is fixed to the fixing piece (65) of the rear region (29) of the diaper (21) and extends laterally therefrom. However, it should be understood that the fixing piece (65) may be formed of a hook-type material, so that it includes a sufficient fixing object (71) without departing from the scope of the present invention. The ring fixture (72) of the illustrated embodiment is a ring-shaped panel fixed on the outer cover (49) of the front area (25) of the diaper (21), and provides a "fixable anywhere" mechanism Fixing system to improve the fixation of a sufficient fixture with a ring fixture. The ¥ -shaped material may include a non-woven fabric having an unlinked pattern, which has continuously connected regions, and defines a range of separated unconnected regions. The fibers or threads in the separated unconnected areas of the fabric are dimensionally stabilized by continuous connected areas that surround or surround each unconnected area, so that no additional film or adhesive support layer is required. The unconnected fan garden is particularly designed to provide space between the fibers or threads in the unconnected range, while maintaining a sufficient opening or hook element large enough to accommodate and engage a complementary hook fixture (71). In particular, a non-woven graphic fabric or fabric may comprise a spunbond nonwoven fabric formed of a single component or multiple component melt-spun threads. For example, the loop material may be a laminated structure that includes a polyethylene component and a polypropylene component and is bonded together in a manner that polypropylene faces away from the outer cover (49) and faces outward to receive the hook fixture (71).

The diaper (21) shown in the first figure also includes a pair of blocking edges, generally designated (75), which are used to block the lateral flow of body fluids. The blocking edge (75) is substantially adjacent to the laterally opposite side edges (31) of the diaper ⑼ and when the diaper is flattened as shown in the first and second figures, the blocking edge (direction) is along the longitudinal direction of the diaper X Within extension. Each blocking edge (75) usually has a free, or unfixed end (π), which is not miscellaneous with the body-shun-ri (51) and the component-free diaper. The elastic strands (79) placed on the barrier ridge (75) 0 and adjacent to the unfixed end of the spurs promote the formation of the barrier film upright, at least perpendicular to the lower region (27) of the diaper (21), so that the diaper is When worn, the blocking film forms a living pattern against the wearer's body. The blocking sheet (75) may extend longitudinally across the entire length of the absorbent body (53) or only partially. When the length of the compilation sheet ⑺) is smaller than the length of the absorbent body (53), the suppressor sheet can be selectively positioned anywhere between the side edges ⑼ in the diaper (21) 胯 lower part (27). In a special part of the present invention, the ' blocking sheet (75) extends the entire length of the absorbent body to absorb body fluids well. Such repellent tablets (75) are generally well known to those skilled in the art, and therefore will not be further described unless required by the present invention. For example, a suitable construction and arrangement of the repellent film (75) is disclosed in K. Enloe! The disclosure of U.S. Patent No. ⑽ 丨 丨 6 issued on 9th of the ninth year is incorporated herein by reference. In addition to the barrier sheet (75), the diaper (21) can also be combined with or replaced by other barrier members. For example (not shown in the figure), other suitable deterrents may include (but are not limited to) elastic waist flaps, air barriers in the front, back or subcondylar area, and the like. The various components of the diaper (21) are assembled together using suitable joining methods, such as adhesion, ultrasonic joining, thermal joining or a combination of these methods. In the illustrated embodiment, the outer cover (49) and the absorber (53) are fixed to each other by an adhesive line (81) such as a hot-melt or pressure-sensitive adhesive. The body-side liner (51) can also be fixed to the outer cover (49) using the same connection method, and can also be fixed to the absorbent body (53). The body-side lining (51) can be secured to the outer covering (49) at the lateral edge of the subjacent region (27), but at least the central region is not limited by this connection. The body-side lining (51) is not completely free from this connection limitation, but can be fixed to the lower 区 (π) ε key by a slight adhesive (83) which will break during use. \ _ 丨 fine 丨 dQe2〇〇fine 3 μ 564172 on the absorber (53). Ideally, the fixation of the bodyside liner to the outer cover (49) is limited to the area of the polar edges of the two to facilitate independent stretching movement of the liner and the outer cover relative to each other. If the diaper (21) is sold in a pre-fixed form, the diaper may also have a passive connection (not shown) connecting the back region (29) and the front region (25).

The diaper (21) may also include a corrugated treatment layer (not shown), which slows down and diffuses the fluctuations or gushing of liquid that may quickly flow into the absorbent body (53). Ideally, the corrugated management layer can receive and maintain the liquid as quickly as it releases the liquid into the absorbent structure. For example, in the illustrated embodiment, the corrugated layer may be positioned between the absorbent body (53) and the body-side liner (51). An example of a suitable corrugated management layer is disclosed in C. Ellis and D. Bishop, U.S. Patent No. 5,486,166, issued January 23, 1986, entitled "Fiber Nonwoven Fabric Corrugation of Absorbent Articles for Personal Care Layers "(FIBROUS NONWOVEN WEB SURGE LAYER FORPERSONAL CARE ABSORBENTARTICLES AND THE LIKE), and US Patent No. 549〇846 issued by C.

The inner fiber connection used herein may be interposed between the interlocking fiber and the absorbent fiber, and the superabsorbent material, and / or between the interlinked fibers. In one embodiment, the connecting fibers are bi-component or multi-component connecting fibers. As used herein, < Even heavy fiber refers to the extrusion of two (i.e., two-component) or individual extruder, but combined in a single ~, mosquito multi-polymer polymer into a shouting dimension. The polymer is generally stably anchored in individual regions across the cross-section of the multicomponent fiber and continuously extends along at least M of the fiber '. It is more desirable to extend along the entire fiber length. The structure of the multi-component fiber can be completely paste, and its towel-polymer system is surrounded by the other; side-by-side arrangement; pie-like arrangement, 'island-like' arrangement, or other suitable arrangement. Bi-component fibers are disclosed in Kanek0 et al. Persons = US Patent No. 51_20, ^-et al. US Patent No. 4,795,668, edited by Ru et al. US Patent No. 554_, and Dou et al. US Patent No. 5,336,552. Bicomponent fibers are also disclosed in Pike No .. No., published by et al., And the recurrence of fibers can be generated by the difference in the expansion and contraction rates of two (or more) polymers. Here, the use of multiple components to connect fibers refers to the connection of fiber components. At least one of them has a -melting temperature 'I! The melting temperature is less than the melting temperature of at least one of the other connecting fiber components. For example, the connecting fiber may be a bicomponent fiber having a sheath-core arrangement in which the sheath component The melting temperature is lower than the temperature of the floating boots.-Once this connecting fiber is heated, the components with a lower melting temperature can melt and bond with nearby absorbent fibers, superabsorbent materials or other connecting fibers. 'And other components often change the state of melting, retaining the integrity of the linking fibers. In other embodiments, the linking fibers may be monofilament or homofilament fibers, bicomponent fibers, etc., and mixtures of these fibers. Linking fibers Ideally composed of a material, or a material that can be easily heated when exposed to excitation energy. In particular, hiding fibers ideally can be exposed to electromagnetic energy. :: But before being affected by non-conductive fibers Consumption is melted into the inner fiber connection in the absorbent structure. Non-conductive heating is a term used to generate electricity in non-conductive materials. This is caused by high E: \ PATENT \ PK-00 丨 08 \ 083l \ pk * 001-083l-l doc2003 / 6/13 18 564172 Loss that occurs when the electric field is alternated in frequency. For example, the electric field frequency is ideally 300 GHz (billion cycles. This method is non-conductive Heating is very fast. This 2 hot hunter puts a non-conductive material into an effective touch-capacitor with two electrodes applied with high voltage, which has a load as a non-conductive function. Although the phase 1 container does not Will young, but actually it will happen, The source of freshness in the form of axonal axis in high resolution. The wind is used for non-conductive heating at a desired energy and the heating target is applied to the electrode. Actual «値 is 2_ to 5_ volts per target thickness. Energy comes from an electronic vibrator capable of generating the desired extremely high frequency. The basic requirement of non-conductive heating is the need to establish a high-fresh alternating electric field on the object or material to be heated.-Once established The electric field, the second demand _ advise. The non-conducting secret properties of hot-marked materials.-The non-material loss of special materials occurs because of the electronic polarization of the material itself 'and can be transmitted by the rotation of the dipole molecules and ions [ The higher the non-conducting loss of the material, the more high-frequency energy it can hold. In the embodiment, the electromagnetic energy is radio frequency or processing, which occurs at 72MHZ, and the-part of the entire energy is conducted by ions. The energy is transferred to the molecules in the working part for heating, while the rest of the energy is transferred in the form of a dipole molecule rotation. In another embodiment, the electromagnetic energy is microwave radiation, which is non-conductive heating at a higher frequency. The main frequencies used in microwave heating are milk and 245_z. Microwave plus teaching is better than: The frequency of non-conductive heating is 10 S times higher. Although the loss coefficient of microwave frequency is usually higher, if the loss is very high, it will generate an approximate volt demand. / Microwave radiation can penetrate the conductive material and be absorbed uniformly, so as to generate thermal energy: Microwave energy can also be absorbed succinctly, providing _ a way of self-concerning the amount of loss caused by foreign materials, allowing overheating The situation is reduced. These combined effects allow microwave heating to be faster, so that surrounding materials are less likely to be heated, have a lower thermal delay, and are therefore well controlled. It should be understood that in addition to the activation of non-conductive heating by connecting fibers or other suitable connecting materials, it can also be activated by infrared-reduction heating or other non-heating, as long as the connecting fibers are activated by the connecting fibers to form a mystic transition. Before, it can be combined with the absorbent Lai (1G1) ', and then activated to form this inner fiber connection, thereby generating a stable absorption knot tree 101).

Or, connect the fiber to the length! / Is 3mm, or at least 6mm. In a further characteristic embodiment, the length of the bonding fibers is 30 mm or more. Alternatively, the length of the connecting fibers may be up to 25 mm, or up to. Furthermore, the absorbent structure (101) may include a connecting fiber having a length close to one of the dimensions (e.g., length or width) of the absorbent structure. -Denier fiber activation. Longer interlocking fiber lengths provide a greater number of interfiber junctions, which helps improve the integrity and permeability of the absorbent structure (101). Synthetic fibers suitable for use as connecting fibers in an absorbent structure (101) include synthetic precursor polymers such as polyolefins, polyamines, polyacetones, polyetheramines, polypotassium potassium esters, polyesters, poly ( Metal meth) acrylates, polyethers, poly (ethylene_ethynyl acetate) random and block copolymers, polyethylene and polyethylene glycol block copolymers, polypropylene oxides and polyethylene oxides Copolymers, and combinations of these compounds) and any suitable synthetic fibers known in the art. In one embodiment, an energy-containing additive may be added to the linking fibers during the generation of the linking fibers, wherein the additives allow the linking fibers to reach the melting temperature quickly, much faster than when no additives are added. In this way, the connection speed of the internal fibers in the absorbent structure (101) is more important than when no additives are added. Ideally, the additives can absorb energy quickly at the frequency of electromagnetic energy (that is, between 0GHz and 300GHz), such as less than one second, ideally less than a quarter of a second, and Da Shaofen is Half a second. However, it should be considered that the absorption structure related to energy absorption and the connection fiber and the absorption fiber are connected within 30 seconds belong to the field of the invention. The melting of the linking fibers will depend on a number of factors, such as energy generation, additive acceptance, fiber denier, which is usually between 1 and 20, and the composition of the parent polymer of the linking fibers. The energy-containing additives can be added during the compounding of the parent polymer from which the fibers are made, or they can be coated to join the fibers after they have been produced. A typical method of combining the additive with the parent fiber is to use a twin screw extruder so that it will combine these ingredients before extrusion. Once extruded, the mixed polymer is usually pelletized for easy storage and transportation. If the connecting fiber is a bicomponent fiber, the energy-containing additive can be added to the two fiber components or only one of them can be added. Energy-containing additives can also be added to the components of one or more bicomponent fibers, ideally continuous, and intermittently spread over the entire length and cross-section of the fiber. If the additive used is not compatible with the parent polymer to which it is added, a "compatibilizer" can be added to improve the mixing effect. Such compatibilizers are known in the art and examples can be found in Gessner

Just like a black object, when exposed to solar energy, absorbs more energy and becomes warmer than the same white object. The energy additive will absorb energy at its specific wavelength. Successful energy containment additives should have a non-conducting loss coefficient, as previously mentioned, this factor should be relatively high. The non-conduction loss coefficient of the energy-containing additive used in the present invention is generally between 0.5 and 15 in the microwave frequency, and more specifically between 5 and 15. It should be noted that the non-conduction loss coefficient is unitless. Ideally, the non-conductive loss of the fiber is between 0 and 1 and more specifically between 0.3 and 0.7. For example, the energy-containing additives may be carbon black, magnetite, silicon carbide, gasification, stones, I clay, magnesium oxide, and nitric oxide. The weight content of the energy additive can be between 2 and 40%, more specifically between 5 and 15%. The connecting fibers may be creped, expandable and / or elastic. / Synthetic fibers combined with this type of energy-accommodating additive, U.S. Patent Application No. 10/034079, filed December 20, 2001, entitled "Targeted Bonding Fibers for Stabilized" Absorbent Structures) is described in more detail, the entire contents of which are incorporated herein by reference. An absorbent structure combined with an attachment fiber having energy-containing additives is described in U.S. Patent Application No. 10/0310, filed on December 20, 2001, entitled "Target Linked Stability Absorbent Structure," (Targeted ON-Line Absorbent, Structures). In addition to having linking fibers that contain energy additives, there is another option. Linking fibers (or at least one component of a multi-component linking fiber) may have a lower melting temperature, such as less than 2000t !, It is more preferably less than 1%, more preferably less than 110%, more preferably less than 90C, and more preferably less than 80C. In this example, the absorbent fibers of the absorbent structure (101) and The superabsorbent material can be used as a source of seam volume to transfer energy indirectly and to melt the linking fibers with low melting temperature. Therefore, the absorbent fiber is used as an energy-containing material and is excited to melt adjacent low melting temperatures in the linking fiber. Polymer to bond with absorbent fibers, superabsorbent materials or each other. This melting will phase: depending on many factors, such as generator energy, moisture content, specific thermal energy, density of the absorbent structure (101) , Fiber denier (usually between 丨 and 20), and the concentration and composition of the low melting temperature polymer that connects the fibers.

Low specific heat energy is very useful between the thermal cycler, because the connection fiber _ The previously absorbed heat is low. Later, low specific heat energy is also useful during the cooling of the absorbing structure ⑽) because the heat is removed from the connecting fiber material, which makes the connecting fiber solidify and stabilize. A suitable specific thermal energy range is 〇i to 〇6 calories per gram. ~ Ideally, the 'linking fiber' also has a high thermal conductivity to allow heat to pass through it quickly. The thermal conductivity is directly proportional to the density and specific heat capacity of the linking fiber. Sin has a higher density of fibers to achieve high thermal conductivity. For example, the linking fiber ideally has a density in excess of 0.94 g / cm3 (g / cc). This is useful for accelerating heating during activation of the linking fiber. Cooling cycles are useful to stabilize the absorbent structure (and). The thermal conductivity of the linking fibers is greater than 0 (Joules / second-Moore-K is preferred. Materials with low melting feed are also ideal for linking fibers. Low melting reduces this amount g 'and allows the connecting fiber to change from _, to melted state during its heating, and then change from melting to melting on subsequent cooling fines. For example, Lian _ fused recording is ideally less than 100 Joules / male 1, more specifically less than 75 joules / gram, and more specifically less than 60 joules / gram. The bonding fiber ideally has a low melting viscosity after activation, that is, once the fiber has settled from it. It becomes roughly melted __. In this way, the linking fiber can flow to the meeting point between the linking fiber and the absorbent fiber ' superabsorbent material and / or other linking fibers to form a stable internal fiber link. For example, 'the melting viscosity of the connecting fibers is ideally less than 100,000 centipoise, more specifically less than 20,000 centipoise, and most specifically less than 10,000 centipoise. The connecting fiber ideally also has a proper surface energy, and can be wetted by the liquid absorbed by the absorption structure (101). This mirabilis is needed for all financial matters. However, if the bonding fiber is not wettable by nature, it can be wetted by using various surfactants known to those skilled in the art. Suitable bonding fibers with a low melting temperature can be made from polyethylene polyethylene g (pE4> vs) block or ik copolymer 'polyethylene-polyethylene oxide (PE-pE〇) block / junction copolymer, poly ^ Ethylene-polyethylene oxide (PP-PE0) block / joint copolymer, polyester, polyacetate, polyamine, polypropionate, 'polyamino acid vinegar (vinegar or vinegar based).

The single structure of the absorbent structure (101) used herein means that the absorbent structure is a single non-woven fabric or a mixed layer product containing multiple absorbent fibers, connecting fibers or superabsorbent materials. In the illustrated embodiments of the first to fourth figures, the single absorbent structure (101) generally includes the entire absorbent body (53) of the diaper (21) (i.e., the size of the absorbent structure substantially defines the size of the absorbent body). However, it is considered that the absorbent body (53) may include more than one layer, at least one of which is the absorbent structure (101) of the present invention, and it is within the scope of the present invention as long as the absorbent structure itself is a single structure. For example, 'in one embodiment, the absorbent structure (101) is formed by first forming or collecting absorbent fibers, superabsorbent materials, and connecting fibers, so that they are activated before the connecting fibers (that is, before the inner fibers in the absorbent structure are connected).

For example, higher concentrations of absorbent fibers, linking fibers, and / or superabsorbent materials can be placed in different tissue layers (i.e., the z-direction) or in different regions (i.e., along the length or across the width) of the absorbent structure. It is also considered that one or more tissue layers or regions of the absorbent structure (101) may be free of connecting fibers and / or superabsorbent materials, as long as the absorbent structure is an integral structure and contains connecting fibers in at least a part of the structure .

On the other hand, towels are uneven in terms of the width of the absorbent structure and / or along the length of the absorbent structure. The "inhomogeneity" used in this case refers to a specific property or characteristic of the absorption structure, which is used to indicate that the property or characteristic is not in the absorption structure, or changes according to the predetermined non-uniformity. That is, a kind of predetermined non-uniformity, the non-uniformity of its large limbs and the tolerance variables that will be produced in the process of manufacturing the absorbent structure. The non-uniformity can be a gentle slope or a gradient of both steps. To indicate that, like concentration, basis weight and / or density in an absorbent structure changes from an organizational layer or region to a ship or layer, and can occur repeatedly in the absorbent structure, or be restricted to the In a specific area. The pre-stabilized absorbent structure (10W may have a thickness that is uneven along the length of the absorbent structure and / or in the direction across the width of the absorbent structure. This thickness is the main surface of the absorbent structure The distance between i is determined by the vertical distance on its main surface in the direction of the absorbing structure 2. The change in thickness can be a gradual or gradient change, or a step-like change, so that the thickness of the absorbing structure One Part to the adjacent part. Therefore, one or more parts of the absorbent structure (101) may have a smaller thickness, while other parts of the absorbent structure may have a higher thickness. For example, in the illustrated implementation In the example, the part of the absorbent structure (101) of the diaper ⑼ absorber (53) (Figures 2 and 4) is generally thicker than the other components of the absorbent structure, and is approximately the same as the front area (M) of the diaper. Let the absorption capacity of the target _ increase. The longitudinal extension of the thicker part (103) of the absorption structure (101) is less than the total length of the absorption structure ΕΛΡΑΤΕΝΉΡΚ-001 〇8 \ 〇831 \ pk-〇〇U083 Μ d 〇c2003 / 6/13 26 degrees' and separated longitudinally inward from the longitudinal ends of the structure by _ distance

In addition, or alternatively, the inconsistent width of the J-structure length is stabilized in advance. This prostitute is a turn between the side edges of the absorption structure, which is determined by the direction of the receiving line. The change in width can be expressed as a gradual or gradient change, or a step change, where the width is suddenly changed from-part of the absorbent structure to-adjacent adjacent parts. For example, the 'absorptive knot_D' may have many clear shapes, including Hosokawa-shaped or τ-shaped, and ideally the anterior or inferior region (27) is better than the anterior diaper (25,37) f. As shown in the first paragraph, the shape of the absorbent body (53) is defined by the absorbent structure (101), and is generally τ-shaped, where the "τ" character ^ horizontal bar roughly corresponds to the front area (25) of the diaper 以Improve the use effect, especially. However, it should be understood that the pre-stabilized absorbent structure ⑽) may have a thickness that is substantially uniform and / or a substantially uniform degree, that is, the absorbent structure is substantially straight and in the absorbent structure. The length direction is parallel to each other. The absorbent structure (101) is formed in accordance with an ideal method of manufacturing an absorbent structure in which absorbent fibers, superabsorbent materials, and connective fibers are green-formed when the connective fibers are in a pre-activated state. Therefore, this absorbent structure _) becomes a single structure with a riding shape and contour (e.g., ideal length 'width and / or thickness) before the activation of the linking fibers (i.e., before the internal_linkage within the absorbent structure occurs). The distribution of the superabsorbent material and fibers in the pre-stabilized absorbent structure (101) can also be controlled in its Gu Gang, so that the basis weight and / or density and the concentration of the material are homogeneous in the domain before the activation of the linking fibers. The Fangweili of the connecting fiber and the absorbent fiber in the absorbent structure are randomly followed by the pre-stabilized absorbent structure, including the longitudinal ends, side edges and main surface of the absorbent structure. σ and then the 'bonding fiber is activated to form an inner fiber layer with the absorbent fiber, superabsorbent material, or other connected fiber, and fix the absorption structure (1G1). More specifically, in the pre-stabilized (absorptive structure (101)-embodiment), it is exposed to high-frequency electromagnetic energy (ie, microwave light emission, radio frequency control, etc.) to melt the connecting fibers and absorb The fiber-shaped Lang fiber connection is then cold-neighbored to solidify the connection fiber, and Xiao firmly stabilizes the connection between the fiber and the absorption fiber and fiber. ΕΛΡΑΤΕΝΊΛΡΚ-001 08 \ 083 l \ pk-001 -0831 -1, doc2003 / 6 / 13 27 564172 Ideally, the absorbent structure is maintained in an unformed state during and after activation of the linking fibers. The unformed used during and after activation of the linking fibers refers to the shape and positioning of the linking fibers within the absorbent structure and Untreated, specifically when the joining fibers are heated and the joining fibers are heated to a substantially melted or activated state, the longitudinal ends, side edges and main faces of the absorbent structure can be changed. For example, in a typical molding operation During or after the bonding fibers are heated, at least one or both major surfaces of the absorbent structure or the absorbent structure are compressed against or within a mold, or the mold is compressed. The body is heated to heat the linking fibers. This type of shaping procedure forces the absorbent structure to reposition in a generally involuntary orientation, and can also be embossed in the shape or even on the main surface of the absorbent structure. Because the absorbent structure (101) is in the bond During or after fiber activation, the unformed state is maintained, so the fiber positioning within the absorbent structure, including its main face, side edges, and longitudinal ends, is generally maintained at random during and after the fiber activation to stabilize the absorbent structure. After the absorption structure (101) is stabilized, it will have approximately the same shape, profile material distribution and other characteristics as the pre-stabilized absorption structure. The stabilized absorption structure (101) ideally has sufficient strength to support the highest tension Load, where 値 is at least 100 grams (g / inch) per inch in the transverse width (γ-axis) direction of the absorbent structure. Alternatively, the strength of a stable absorbent structure (101) may be at least 200 g / mch, or At least 500 g / inch. In other respects, the strength of the absorbent structure (ioi) can be up to 10,000 g / inch, or more. Alternatively, the strength can be up to 5000 g / in. ch, or up to 2000 g / inch. When measuring the strength of a stable absorbent structure (ιοί), any pre-formed, individually provided reinforcing members should not be measured together. Such reinforcing members (not shown) can be borrowed from a cotton Hemp fabric, a continuous monofilament fiber, yarn, elastic monofilament, a tissue, a woven fabric, a nonwoven fabric, an elastic film, a polymeric film, a reinforcing substrate, etc. or a combination thereof to provide stability absorption The structure (101) can be constructed to have sufficient strength to support the highest negative tension of%, which is specifically greater than the highest tensile load that the absorbing structure can support before the connecting fibers are activated. In a specific aspect, the absorbing structure ( 101) can be constructed to have sufficient strength to support a maximum tensile load, which is at least 100% greater than the maximum tensile load that the absorbing structure can support before the connecting fibers are activated. Alternatively, the stable structure (101) can support a maximum tensile load of at least greater than 200%. Alternatively, the stability structure (101) may be constructed to support a maximum tensile load of at least greater than 300%. The percentage increase of the maximum supported load can be calculated by the following formula: ΕΛΡΑΤΕΝΤΛΡΚ-001 08 \ 0831 \ pk-001 -0831 -1 .doc2003 / 6/13 28 564172 Calculated: 100x (F2-Fl) / Fl; where

Fl = the highest tensile load supported by the absorbent structure before the activation of the linking fibers, and F2 = the highest tensile load that the stable absorbent structure can support. 、、 Absorbing structure _) The highest negative radiation that can be supported is from the test method T494 om-96 of Nong Nian, named "Tensiie Properties of paper and Paperboard," To determine (which uses the stability ratio of the extension device). The test sample is 1 inch (2.54 cm) wide and 6 inches (ls Μ㈣) in length. The pliers used are INSTRON part number 2712-001 (available from sintech, Inc., which has an office in Research Triangle Park, North Carolina, USA), and is arranged in advance so that the separation distance is 5 inches (12.7 cm). The speed of passing through the head is 12.7 mm / min, and The test was performed using a MTS Systems Corp. model RT / 1 test machine, which is controlled by TESTWOKS version 4.0 software, which is available from MTS Systems Corp., which has services in Eden Prairie, Minnesota, USA The equivalent equipment is also available. The liquid permeability of the absorbent structure (101) will also be affected by the binding of the binding fibers. The liquid permeability of the stable absorbent structure is defined by Darcy's Law (Darcy, s Law) and To define a particular Measure the absorption saturation of liquid. More specifically, liquid permeability here refers to the property defined by the following liquid permeability test. Liquid permeability test A suitable liquid permeability test equipment is shown in the fifteenth and sixteenth. Figure. This test device contains a barrel (1134) and a piston, roughly as shown in (1136). The piston (1136) contains a cylindrical LEXAN shaft (1138) 'which has a concentric cylinder that passes down through the longitudinal axis of the shaft Hole (1140). Both ends of the shaft (1138) are processed to provide the ends ⑴42, 1146). A heavy object, as shown in (1148), 'is placed on the end (1142) and has at least a portion passing through its center Cylindrical hole (1148a)-round piston head ⑴50) is placed on the other end (1146) and has a concentricity formed by seven holes (1160) (directly controlled by the valley holes of 0.95 cm) The inner ring and the outer concentric outer ring formed by 14 holes (the diameter of each hole is 0.95 cm). The holes (1154, 1160) penetrate from the top of the piston head (1150) to the bottom. The piston head (115〇) It also has a cylindrical hole (1162) passing through its center to engage the end (1146) of the shaft (U38). The bottom of the piston head (1150) can also cover a E: \ PATENT \ PK-001 08 \ 0831 \ pk-001 -0831 -1 doc2003 / 6/13 9 564172 stainless steel mesh (1164), this mesh has a square mesh with M9 micron mesh hole. A typical material for this piston is McMaster-Carr Supply part number 85385T972, which has an office in Chicago, Ontario, u.S.A. The bottom end of the barrel (1134) is connected with a stainless steel cloth net Xue Xuan 66), which can be tensioned by a double shaft before connection. The mesh sieve (lobby 1) has a square mesh with a mesh size of 105 microns. A representative material of this screen is McMaster-Carr Supply part number 85385T976, which has offices in Chicago, Illinois, U.S.A. A composite material (116S) is supported on a mesh screen (1166).

The barrel (1134) is either passed through a transparent LEXAN rod or its equivalent, or is pierced from a LEXAN tube or its equivalent, and the inside diameter of the barrel (1134) is 600 cm and the height is ι0 cm . The drum includes a set of drainage holes (not shown) or other elements suitable for maintaining the liquid in the drum to maintain the height of the liquid on the screen (1166) to 7.8 cm. The piston head (ι150) is mechanically treated with a LEXAN rod or equivalent, so that it has a height of 16 mm and has the smallest side wall gap size and can slide freely just inside the drum (1134). A hole (1162) in the center of the piston head (1150) is used to mate with the shaft end (1146) and fit snugly with the shaft end (1146), and is watertight. The shaft (1138) was treated with a LEXAN rod or equivalent to a diameter of 2.32 cm and an inner diameter of 0.64 cm. The end (1146) is 2.54 cm in length and 1.52 cm in diameter, forming a ring-shaped shoulder to support the weight (1148). The inner weight of the ring weight (1148) is i 59cm, which makes it slip on the end (1142) of the shaft (1138) and stop on the ring-shaped shoulder formed by the shaft. The annular weight may be made of stainless steel or other materials that are resistant to 0.9% isotonic saline solution. The combined weight of the piston (1136) and the weight (1148) is about 596 g, and the corresponding pressure is 28 27 cm2. There is 20.7 dyne in the area. The drum is usually parked on a 16-mesh hardened stainless steel support screen (not shown) as the Luo liquid mud passes through the piston / drum equipment. Alternatively, the hybrid / drum combination can be placed on a support ring (not shown) that matches the drum wall, but does not effectively restrict flow from the bottom of the cylinder. The piston and weight were placed in an empty drum to measure the size from the bottom of the weight to the top of the drum. This measurement is made using a caliper with a minimum unit of 0.01 mm. Alternatively, it can also be measured using a volume measuring instrument with an accuracy of 0.01 mm, such as the Model IDF-1050E measuring instrument of Mitut〇 America 〇 〇rp〇rati〇n, which is in Aurora,] [iii〇nis, us A has an office. This measurement is then used to calculate the height of the bed. Measure the empty sentiment of each bucket and keep track of it. ΕΛΡΑΤΕΝ1ΛΡΚ-001 08 \ 083 l \ pk-001-0831-1.doc2003 / 6/13 564172 The use of the piston and weight is ". When the absorbent structure sample is murmured, the same piston and weight should be used for measurement. The sample of the absorbent structure used to determine the liquid permeability is by placing a round sample (such as a previous down sample) in-having G.9% (w / V) legs in her _permeable_Jingsulin ^ contact) 60 minutes' to make it expand to 60 mm. At this time the salt water can be placed in a plate. Coarse rubber or rubber with a uniform mesh opening and a mesh size of about 2_15 mm is used to allow the saline to contact the permeate cup to expand the sample. At the end of 60 minutes, the piston and weight are placed on the bulged sample in the drum, and then the drum is piston, and the saline and the sample are completely taken from the saline. The thickness of the expanded sample was measured using a micrometer to measure the size of the mosquito from the bottom of the weight to the top of the drum. Alternatively, this measurement can be measured using -accuracy to read mm__ instruments, such as obtained from the Office Post. Model ID㈣50E measuring instrument of Αιη_ C ^ _ion, which has an office in Mrora, imnois, us ’which is constant from the fine thickness of Eno. Let the thickness obtained by absorbing and expanding the female 値 minus the thickness obtained from the measurement empty, the piston and the weight. The secret ship is inflated "H". The measurement of the liquid permeability of the absorption structure was started by adding a NaC1 solution to a drum (1168) with a swollen sample (1168), a piston (50), and a weight (0134) of a weight (48). ㈣The skin was added so that the food vein height on the bottom of the sample was χ8. Gently measure the weight of the ground; the volume of the nocturnal body by expanding the sample. Once the liquid is highly stable and maintained at Μ⑽, it is collected every second for 30 seconds according to the data '. The flow rate Q through the expanded sample (1168) is measured in units of liquid crystals, which is measured by the smallest squared equivalent of the liquid passing through the sample (ιΐ68) (g) in unit time (seconds). Permeability of liquid in square micrometer is obtained from the following formula: K = [QxHxMux 108] / [AxRh〇xP] Permeability of K liquid in Bazhong (square micrometer), moving rate (g / sec), expansion absorption Structural sample height (cm), Mu = liquid viscosity (poise), in = cross-sectional area of liquid flow _2), version ^ liquid density (gW), and p = hydrostatic pressure (dyne / cm2). Hydrostatic pressure is calculated from: P = Rh〇xgxh E: \ PATENT \ PK-001 08 \ 0831 \ pk-001-0831-1 doc2003 / 6/13 31 564172 where Rho = liquid density (g / cm3), g = gravitational acceleration, usually 981 cm / sec2, and the liquid height, which is 7.8 cm mentioned in the liquid permeability test equipment mentioned above. In general, the higher the liquid permeability of the absorbent structure when saturated, the more open the structure. Therefore, the absorbent structure can absorb the extra liquid more easily and is less likely to leak liquid. Without a bonding material, the liquid permeability of the nonwoven absorbent structure is based only on the characteristics of the superabsorbent material and the absorbent fibers, so the liquid permeability will be lower, such as less than 20 square microns. The integrity of the absorbent structure (101), more specifically the void volume, can be increased by stabilizing the structure with the linking material, more specifically the multi-component linking fibers' to fully increase the liquid permeability of the absorbent structure Sex. For example, after the activation of the connecting fibers, the liquid permeability measured by the absorbent structure of the stable absorbent structure (101) through the liquid permeability test described above is ideally greater than 20 square microns, and more preferably greater than 40 square microns. , More preferably greater than 60 square microns. It should be understood that the liquid permeability may be uneven in at least one of the width and length of the absorbent structure (101), as long as the liquid permeability of the absorbent structure itself is at least greater than 20 square microns. Without wishing to be limited by theory, one should also believe that too high a concentration of linking fibers in a stable absorbent structure will negatively affect the liquid permeability of the absorbent structure. In order to help increase the liquid permeability of the absorbent structure, the concentration of the linking fibers in the absorbent structure is desirably between 0.1% and 10, and more preferably between 0.1% and 5%. increase. By forming the absorbent structure (iOi) before the activation of the linking fibers, it is substantially in its final form, i.e., it has the desired length, width, thickness and / or basis weight without the need for additional shaping, i.e. cutting. Therefore, even if the width of the absorbent structure is non-uniform, the side edge of the absorbent structure (101) remains in a cut state after the connecting fibers are activated. It is also considered that the longitudinal ends of the absorbent structure (101) may not be cut 'as if each absorbent structure was directly formed into a separate form, rather than a continuous fabric which was later cut into separate structures. The side edges of the prior art stability absorbent structure must be cut to an ideal width profile, usually with a profiled edge profile, or surface profile, which is roughly concave as shown in Figure 11. I do not want to be limited by special theory to believe that the concave crotch surface profile is formed by the fibrous material on the side edge because the absorbent structure is squeezed 'when its side edge is cut. On the contrary, the uncut side edge of the stability absorbing structure (101) of the present invention ideally has a cross-sectional edge profile or surface profile, such as a substantially straight line and ideally a convex surface 'instead of being concave. For example, one of the stable absorbing structures (101) is a cut E: \ PATENT \ PK-001 08 \ 083 l \ pk-001 -0831 -1, doc2003 / 6/13 32 564172 The profile of the side edge of the side edge is The twelfth figure shows that the surface contour of the side edge is convex. Figures 13 and 14 illustrate the difference in fiber positioning between the uncut side edges of the absorbent structure (101) and the cut edge of the prior art structure, respectively. As shown in the thirteenth figure, there is no certainty that the fibers on the cutting edge are positioned on the entire surface contour. Previously, the fiber fixation on the cutting edge of the fixed absorption structure was split, especially on the surface corridor: 急急 片 # again, so it is considered involuntary along the entire surface contour. Test 1-Edge test is performed-Test is performed to quantify the cross section of the side edge of the traditional stable absorption structure (the middle side edge has been cut to form an ideal width profile) and the stable absorption of the shaft according to the present invention Structure (101) is the difference # between the cross-section wheel temples of the cutting side edges. The five samples in group _ correspond to the traditional stable absorption structure, in which the side edges are cut. The basis weight of each test sample is present and the thickness is 0.25 inch pairs (about 8 mm), and from the side edge of the absorption structure is 0.05 inch leaves (about 12㈣. The five samples in the second group correspond to the hair_stability The absorbent structure, more specifically, corresponds to the absorbent structure (101) shown in the tenth figure, which has a ten-centre region of increasing thickness to relax the longitudinal ends and side edges of the absorbent structure.

More specifically, the light intensity reflected by the spectroscopic beam and the light beam was measured using the 60-Zi field, and the width of each frame of the towel was 0. = mm. The arrangement is for some structures (such as μ, which only reflects the black structure tissue paper outward from the side edge of the sample ', while the remaining structures reflect the straight line extending from the sample inward and are roughly equal to the sample χ_γ: l \ pk-00! -0831 -1 d〇c2003 / 6/13 33 564172 The edge of the sample perpendicular to the side edge of surface I. The measured brightness is based on a 6-point gray scale, where 0 gray scale units are equal to black ' The 64 gray scale units are white. The self-color class is set at α75 volts, so that the approximate maximum party degree within a frame is 90 to 96% of the maximum gray scale.

The -absorptive structure is a two-layer separation layer consisting of-the base layer and-the upper layer whose width and length are cut smaller than that of the base, and this upper layer is recorded in the middle portion of the side edges and longitudinal ends of the base layer. Three samples of such absorbent structures were used.

Systems (located in NA "Bothell, Washington, USA.) Pickers / Marconi camera. The ship emitted by the camera passes through the sample, and its field light is blocked by the black construction tissue. The light passing through the sample is blocked by the sample. A suitable analysis system is used for imaging, such as Cambridge / Leica from Bockbaker, IUmois, USA. Its brand name is Quanmetet 97 ° Image Analysis System to determine the intensity of light passing through the sample. The image forming system uses A 20 dirty Nikon lens', with F to c adapter) to complete, as obtained from Nikon OEM Sales of Full, N γ, usa, which has a variety of connected neutral density filters (such as alternating and polar ), The intensity of the light reaching the scanner has been controlled. The working distance between the lens and the test sample is 457 mm (approximately 18 inches). The total field size of 900 pixels is 253 mm (approximately 10 inches). Sample The optical shell pattern below the length (for example, the sample portion that is not blocked by the black construction tissue paper, including the area of increased thickness) is determined using the software program of Annex 2. According to the sample reading, the absorption structure_axis direction is used to determine Measurement pending Samples. However, samples should also be taken according to the horizontal axis of the absorption structure. _ The gauge brightness of the sample is measured on the 60 structures below the sample length. 'The width of each structure is 3 bands. The measured brightness is According to the _ 6-point gray scale, the unit of f 0 is equal to black and the unit of 64 is white. The brightness level under the sample length (that is, corresponding to the change in sample thickness) is determined by multiplying the frame measurement 値 by U (that is, boosting force)口 10%). If the phase E: \ PATENT \ PK-001 08 \ 083 l \ pk-001 -0831-1, doc2003 / 6/13 35 564172 next to the measured data of the architecture exceeds this threshold, the hierarchy will start. The brightness level under the sample length (determined by the %% confidence range obtained by the traditional τ statistical analysis of N = 4 or 3 used by students) is averaged to determine the average level of each group of samples. For the sample of the series (the financial and financial organization layer is on the silk base layer), the average brightness level ranges from 4.02 to 6.84 grayscale units s / mm, among which the number is 5 43 grayscale units, s / mm In contrast, the samples of the stable absorption structure (having an integrated structure) according to the present invention have an average redundancy gray scale of 0.93 to 2.31 gray. Step unit s / mm, where the number is 62 gray-scale units s / mm. Therefore, ideally, the average brightness level of the stable absorption structure (101) of the present invention has an uneven thickness in the width direction, and is ideally 05 to 3 () gray scale unit 3 / orbital, and more reasonably, 0.93 to 2.31 gray scale unit s / mm, which is determined by the absorption structure brightness test. At positions where the thickness is uneven along the length of the structure, the average brightness level range in the middle of the longitudinal ends in the length direction is also 0.5 to 3.0 gray scale units s / mm (measured by the absorption structure brightness test), which is ideal. It is 0.93 to 2.31 gray scale units s / mm. In the position where the pre-stabilized absorption structure (101) is activated by non-conductive heating (for example, exposed to electromagnetic energy), the stable absorption structure also has the effect of the existence of the connection fiber and subsequent activation of electromagnetic energy. The resulting unique physical properties. These properties can be qualitatively and quantitatively measured using oxidation degrees and position measurements, as well as the efficiency of attachment within the absorbent structure. More specifically 'ultraviolet, visible, near-infrared, infrared, and Raman spectroscopy; surface analysis; differential scanning colorimetry, chromatographic separation; and various microscopy techniques can demonstrate heat transfer by pair / watt or infrared radiation And the "external" heating has unique properties compared to the "internal" heating using non-conductive technology. By infrared and convective heating, radiant energy is converted into thermal energy on the surface of the rapidly absorbing structure. Thermal energy on the external surface of the absorbent structure will eventually diffuse toward the center of the absorbent structure through heat conduction. This heating process is slower and requires more time for the center of the absorbent structure to reach a critical temperature capable of melting the connecting fibers in the center of the prone structure. The slow process of heat transfer is based on the thermal conductivity of the structure and its overall size (e.g. thickness). Therefore, in this type of heating process, the greater oxidation of the fibers occurs towards the external surface of the structure (or specifically on the external surface). Thermal bonding in this way also produces yellow fibers on the external surface of the absorbent structure. E: \ PATENT \ PK-001 08 \ 0831 \ pk-001-0831-1, doc2003 / 6/13 564172 For non-conductive heating (even using electromagnetic energy), the maximum temperature of the absorption structure (1〇1) is also Near the outer surface. However, the temperature rising in the center of the absorbent structure (1 () 1) is almost equal to the temperature of the outer surface. This is because the scale conduction heating program is active and direct. The energy transfer in the center of the absorbing structure is less affected by thermal conductivity, but rather by the non-conductive nature and length of the non-conductive range of the absorbing material. In other words, the heating effect usually occurs from the center of the absorption structure (ιιι) toward the external surface. The implementation time of the infrared energy must be 3 to 30 times longer than that of non-conductive heating, so that the entire absorption structure is heated uniformly. More specifically, the need for so much extension time is to obtain the ideal temperature critical threshold (such as the melting temperature of the connected fibers) in the center of the suction structure. When properly implemented, non-conductive heating is quickly generated and relatively uniform. Fast and nano-scale direct heating prevents substantial thermal degradation of the polymer in the heated absorbent structure. The percentage of oxidation-depleting compounds that occur in any particular hybrid is exposed to elevated temperatures (such as 75. 0 is proportional to the time. Infrared heating can maintain a higher surface temperature throughout the heating cycle than microwave heating. Μ The percentage of oxidation caused by the addition and subtraction of the material on the outer silk surface is 5 to 35 times (or more) than the percentage of Junsheng on the silk surface outside the non-material recording structure. Therefore, the microwave radiation is used to heat it. The absorption structure will produce a structure whose oxidation on the outer surface will be 5 times less than the shirt, more specifically 3 times less. The difference in oxidation is caused by the addition of a solution on the silk surface. The analytical technique described previously. In this application, typical compounds produced by oxidative degradation include high color negative (interrogative absorption). These color compounds are produced by recognizable unsaturated spear conditions. Examples include polymerizing unsaturated carbon compounds, unsaturated radicals, containing organic bond groups, thieves, and oxidative / degradation mechanisms with free near-formed, excluded reactions' and arbitrary chain breaks to form conjugated duplexes Condensed compounds. In general, the increased oxidation can be easily found with the naked eye, which makes materials using infrared and convective heating look yellower and therefore feel poorer.-A species used to analyze lindane and cellulose materials ± The fast-linking 'non-destructive method' of Jilin's compounds is described here. UV and visible spectra are measured on a controlled and heated sample. The final light?

The maximum absorption ratio of ultraviolet to the visible spectrum can be as high as 4% for the chemicals produced and the approximate concentration of white. Information. This basic program can use UV and visible fluorescence, photo-divergence, and infrared spectrum generation again to provide similar and complementary results. For more detailed structural analysis, polymers and Vitamin materials can be dissolved in a suitable solvent, processed by liquid chromatography, and further analyzed using the above-mentioned spectroscopy techniques or a large number of spectra to determine the structure and molecular weight of any degrading compounds. These compounds usually have a high degree of color , Such as yellow or brown, this is due to the brown effect of thermal degradation and oxidation. There are many literatures describing detailed analysis of degrading compounds in synthetic and natural polymers, and most of the techniques are sufficient to measure the entire cross-section of the heated structure. The relative amount of oxidation on the cross-section. In addition, the use of an iron microscope with iron tetraoxide consumption can reveal the integrity of the internal bond junctions and indicate the maximum heating temperature to reach any part of the heated structure during the procedure. Ten illustrations-an embodiment of a device, designated by 标号), for manufacturing a stable absorption structure (101) according to the present invention and the method described above. The device 021) has a designated length or machine direction (123), a designated wide-length coin transverse (125) across the machine direction, and a paper thickness or z direction. For the purposes of this disclosure, the machine direction (123) is the direction in which a particular component or material is conveyed longitudinally 'or along and through a device-specific, original location. The machine transverse direction (125) is roughly on the plane where the material is conveyed and passes through the program, and is perpendicular to the original machine direction (123). The z direction (127) is perpendicular to the machine direction (123) and the machine transverse direction (125), respectively, and extends substantially along a depth direction 'thickness vector. In the illustrated embodiment, the machine direction (123) corresponds to the longitudinal X axis of the diaper ⑼ in the figure-and the machine direction ⑽) corresponds to the transverse γ of the diaper. Fortunately, the device (m) contains an -air forming device, as In the fifth and sixth figures, reference numeral ⑽) has a shaped surface ⑴ 5) which is movable, has holes and extends along the circumference of the drum ⑽) (the reference numbers basically represent their entities). The drum is attached to a shaft (139) connected to a connection (H3) by a bearing (M1) (seventh picture. As shown in the seventh picture, & includes an AND shaft (m ') The connected mounting wall (I45) rotates in connection with it. The shaft ⑽) is driven by a suitable motor or linear shaft (not shown) to rotate counterclockwise, as shown in the fifth and sixth figures. The ring wall (⑷) cantilever the forming surface ⑽) and the opposite side of the drum (n7) is open. On the forming surface (135), an air guide E: \ PATENT \ PK-001 08 \ 0831 \ pk-001-0831-1 doc2003 / 6/13 38 564172 tube (丨 47) is placed in the direction of inward emission. Through the drum interior. The hollow tube (147) has an arched, elongated inlet (149) below the porous forming surface (135) (described later in more detail) to allow liquid to circulate between the hollow tube and the forming surface. The empty air duct ㈣) is connected to an empty air supply duct (151) connected to the empty air source ⑽) (shown schematically in the seventh figure). For example, the empty source (153) may be a suction fan. The hollow tube (147) is connected to the hollow supply tube (151) along the outer peripheral surface of the tube and extends along the circumference of the tube. The hollow duct (147) projects radially from the hollow supply duct (151) toward the forming surface (135) and includes laterally spaced side walls (147A) and angled spaced end walls (147B). The shaft (137) extends through the wall (145) and enters the hollow supply duct (151), and is in contact with a bearing (155) inside the duct. The bearing (155) is sealed by the empty supply duct (151) so that after the air enters the duct, the air around the shaft (139) cannot be sucked. The stent (157) and the entire catheter are supported by an upper stent (159). The Bayi drum frame (161) (seventh picture) is mounted on the wall (145) of the drum (137) and the drum frame (161) has a small hole in its wire range, allowing the flow to move completely freely through the drum rotation Like ^ 气. The drum frame (161) is generally tubular and extends around the axis of rotation of the shaft ⑽) and near the alcove). The drum frame (161) is suspended from the drum wall (145) and has a -radially facing surface, which is adjacent to the entrance (149) of the hollow tube (147). A drum frame cover (163) is installed on the inward facing surface of the drum frame (161) in order to provide a tempered seal between the frame ⑽) and the entrance (149) of the air duct 〇47). For sliding, and sealingly engages the wall (147A) of the hollow catheter. A cover (not shown) is also installed on the end wall (1 peach) of the hollow tube (14) for sliding, and is sealedly engaged with the surface of the drum frame (⑹) facing inward. The cover can be sealed and allowed to slide. Made of suitable materials. Looking back at the sixth figure, the equipment (⑵) further includes a forming chamber (m), and the forming surface (⑽) can be connected to the rotating drum (I37) to move through the forming chamber (m). More specifically, in the embodiment shown in the figure, 'the molding surface (n5) moves counterclockwise in the molding chamber (m), which is roughly from the two entrances') (the molding surface enters through this entrance ⑽) Forming to fiber-free material) to-exit (175) through which the forming surface exits the forming chamber, and a pre-stabilized absorption structure (101) is formed in the forming chamber). Alternatively, the drum cymbal) may be rotated clockwise with respect to the forming chamber (=). The forming room is supported by a suitable support frame (not shown). This support frame can be tied to and / or connected to other suitable ΕΛΡΑΤΕΝΤ \ ΡΚ-001 〇8 \ 〇83 l if needed or desired \ pk-001 -0831 -1, doc2003 / 6/13 39 On the component " and collecting fiber lining, such as cotton wool (Π7) (fifth and sixth figures) in the form of absorbent fiber, from -i, iW (not显 ㈣ is transported to the _ fiberizing machine (Μ), which can be-a traditional rotating clock /: 的, a rotating cotton cleaning roller or other suitable fiberizing device. Fiberizing machine (197) $ $ 絮 (^ 77 ) Is separated into individual, loosely absorbed fibers, and these fibers are transferred from the fiberizing machine to the openings y to (171). In the illustrated embodiment, the fiberizing machine (located at the forming chamber) (⑺) ^ Fang However, 'it should be understood that the fiberizing machine (I79) can also be located away from the forming room (Π1), and other suitable devices in the absorption industry are transported to the inside of the forming room in other ways, which still belongs to the scope of the present invention. + The fibers or particles of the superabsorbent material can be removed using traditional mechanisms such as pipes, channels, spreaders, nozzles, etc., and combinations of these items Into the forming chamber (171). In the illustrated embodiment, the 'superabsorbent material is fed into the forming chamber (171) through a delivery duct (181) and a nozzle system (not shown). The fiber material is connected from a suitable connection. The fiber supply source (183) is sent (in the form of a bale) to a suitable opening device (185) to roughly separate the connecting fibers into individual, loose connecting fibers. For example, the opening device (185) Can be used for selection, carding, planing, etc., and combinations of these actions. Then, the selected amount of connected fiber is directed to a metering device (187), which supplies a controlled amount of connected fiber to a connected fiber delivery catheter (189). For example, the linked fiber metering device (187) may be a model CAM_1X12 device, available from Fiber Controls, Inc., with an office in Gastonia, North Carolina, U.S. A bellows ( 191) or other suitable device to help the connecting fibers pass through the delivery catheter (189). In the illustrated embodiment, the connecting fiber catheter sends the connecting fiber into the fiberizing machine (171) so that it can be homogeneously mixed with the absorbent fiber, Then absorbed The homogeneous mixture with the linking fibers is sent to the forming chamber (171). However, it should be understood that the linking fibers can also be sent to the interior of the forming chamber separately from the absorbent fibers, and is sent by the fiberizing machine (179) in addition to the absorbent fibers. To a position other than the conveying point of the forming chamber. If the connecting fibers are fed into the forming chamber (171) closer to the forming entrance (173), the connecting fibers will concentrate on the absorption formed on the forming surface (135). The main surface of the structure (101), or the molding surface side (193) or the inside. If the connecting fiber is sent to the forming chamber (171), which is closer to the exit of the forming chamber E: \ PATENT \ PK-001 08 \ 083 l \ pk-001 -0831 -1 doc2003 / 6 / l 3 564172 (I75) ' Then the connecting fiber will be on the main surface of the absorbent structure (101), or on the free surface side (195) (sixth figure) or outside than the needle. Alternatively, the linking fibers may be combined with or incorporated into the source of the absorbent fibers, rather than entering the air forming device (m) separately from the absorbent fibers. For example, the binding fibers can be mixed with the absorbent fibers before the absorbent fibers are sent to a supply roller (i.e., cotton batt 7). The porous forming surface (135) is defined by a series of forming elements or forming members (201) in the illustrated embodiment. The forming members are arranged end-to-end around the forming drum (137), and are separately connected to the drum. . As shown in the eighth figure, the forming members ⑼1} are respectively defined—for receiving air-fiber material “roughly the same”. These figures correspond to the ideal length, width, and thickness of the individual absorbent structure (1Gii), and the individual absorbent structure (101) will repeat around the periphery of the drum. However, ^ repeated or non-repeated patterns can be used in the hairpin. It should also be understood that continuous, non-patterned absorption structures can be formed on the forming surface (135). For example, the reduced surface is flat. , Or shaped absorbent structure is usually rectangular, and then processed into the desired shape (such as cutting or other methods). Referring to the eighth to tenth drawings, the forming member (2101) includes a porous member (5), which is operable on the forming drum (135) and is different from it. The forming member (2Q5) may include-coarse mesh screen, a mesh gauze,-hard cable fabric,-perforated member, etc., and these still compositions. In the embodiment shown in the tenth figure, a plurality of open channels (209) are formed to be grooved, which extend approximately radially to allow air or other selected gases to be free from the outer surface of the drum to the inside of the drum. Ground flow. The channel (209) can have any desired cross-sectional shape, such as circular, oval, hexagonal, pentagonal, other polygonal shapes, etc., as well as the composition of these shapes. With particular reference to the tenth figure, the outermost surface defined by the countersink member ⑽) in the radial direction may be equipped with a surface profile of uneven depth (i.e., the z-direction (127)) to form the formed surface (135) The pre-stabilized absorbent structure (101) provides an ideal uneven thickness. In an ideal arrangement, the variation in the z-direction of the surface profile may have a selected pattern, and the pattern of the project may be regular or irregular. For example, the pattern of the surface contour can be designed to provide a selected repeating pattern along the circumference of the shaped drum. The surface profile of the porous member (205) of Fig. 10 thus defines a longitudinally opposite end region 'which has a first-pina degree; and a central region which has a second average depth which is greater than the first average depth. Each of the end regions having the first average depth can be provided to the absorbing structure (101) formed by E: \ PATENT \ PK-001 08 \ 0831 \ pk-001-083M.doc2003 / 6/13 564172 on the forming surface (I35) A lower basis weight area and / or thickness, and a financial center with a larger second average depth _ can be transferred to provide higher base area or thickness area. The phases ^ 'may each have a first-level flatness scale which may be substantially adjacent to an adjacent area having a larger second depth. It should also be understood that the porous member (2G5) can be designed to have—through the forming surface, the Z direction of the width, the surface profile, to the absorbent structure formed on the forming surface, and through the uneven basis weight and / or thickness of its width. . In an ideal bank, the surface of the porous member (2G5) is lightly fixed—roughly trapezoidal. Or 'round shot' defines hemispherical or flat. In the illustrated embodiment, the depth defined by the porous member (205) is turned into a pocket area ㈣, which extends along the-part of the length of the forming surface 依 in the direction ϋ of the machine, and the domain crosses the width. The central part forms the absorption structure shown in the fourth figure.

So' resistance The mechanism can make the forming surface 维 5) the fiber partial thief covered by the blocking structure to reduce this amount of money. Miscellaneous textures can be set up to form other desirable properties of the absorbent structure (1G1), such as forming a series of notches on a formed absorbent structure (not shown). ·, Can provide confession-Sense Lin, turn to the station to cut the fabric that is longitudinally connected to the absorbing structure (ι〇1) on the forming surface (135) into individual absorbing structures, which can help find the place and place it. Still referring to the eighth to tenth drawings, the forming member (201) may also include one or more side decorative members (213) 'sometimes also referred to as a contour ring to provide an ideal for the absorbent structure (101). Shape (i.e. width outline). For example, in the illustrated embodiment, the side decorative member (213) is made of a pair of laterally opposed ring members lion 'which can be laterally opposed to each other around the forming drum (137). Each member (213) has a non-uniform inner side wall (215) along its length, so that the lateral decoration member (213) laterally opposite the inner side wall defines the absorption structure (101) on the forming surface (135). Width outline. More specifically, the inner side wall (215) of the side decoration member (213) has a meandering outline when it extends in the machine direction (123). Therefore, the side decorative member (213) can provide a narrow and wide area of the forming member (201). Therefore, the absorbent structure (101) output from the air forming device (1; 31) may have a width profile which is non-uniform in length along at least a part of the structure. E: \ PATENT \ PK-001 〇8 \ 〇83 l \ pk-001-0831-l.doc2003 / 6/13 42 564172 In another aspect, at least one of the side decorative members (213) may have one or More main flaps (not shown). For example, individual main flaps can be used to make or verify the length of each intended absorbent structure (101) on the circumference of the forming drum (137). Such side decorative members (213) are particularly advantageous when air-forming devices (131) are used to produce disposable absorbent structures (e.g., diapers, child training pants, feminine care products, adult incontinence products, etc.). It should be understood that the inner sidewall (215) of the side decorative member (213) may also be linear (i.e., parallel to the machine direction (213)) to provide a generally rectangular, band-shaped absorbent structure (101). . It should also be understood that the side edges (105) of the absorbent structure (101) can also be provided by cutting and removing, cutting and folding, and a combination of these methods. The forming surface (135) is considered here as While explaining a part of the example of the drum (137), it is understood that other techniques for providing a forming surface can also be utilized and deviate from the scope of the present invention. For example, the forming surface (135) may be formed by an endless forming belt (not shown). Such forming belts are shown in U.S. Pat. No. 5,466,409, entitled "FORming BELT FOR THREE-DIMENSIONAL FORMING APPLICATIONS", which was published on November 14, 1995. In the operation of manufacturing a formed 'non-woven pre-stabilized absorbent structure, that is, before the connecting fibers are activated to form the inner fiber connection within the absorbent structure, the hollow source (153) (seventh figure) will be in the hollow tube (147) Hollowing is generated relative to the interior of the forming chamber (171). When the molding surface (135) enters and then passes through the molding chamber (171) toward the molding chamber exit (175), the absorption fibers, bonding fibers and superabsorbent materials in the molding chamber are effectively transported or conveyed by an air-carrying air stream, and are oriented toward the porous molding. The emptiness of the surface attracts inward. It should be understood that the absorbent fibers, superabsorbent materials and bonding fibers may also be delivered by any suitable fluid medium in the forming chamber (171). Therefore, it should be understood that any gas system used as a conveying medium is a general reference, and it includes any fluid having a conveying effect. Air passes inwardly through the forming surface (135) and exits the drum (137) through the air supply duct (151). Absorbent fibers, connecting fibers and superabsorbent materials are collected by forming members (201) to form a pre-stable absorbent structure (101). It should be understood that the intensity or extent of the hollow suction effect can be selectively adjusted to control the density of the absorbent structure (101) formed on the forming surface (135). Higher suction strength can result in higher density or low porosity absorbent structure (101), while lower suction strength can result in lower density or higher porosity E: \ PATENT \ PK-001 08 \ 083l \ pk -〇〇1.〇g31. | Doc2003 / 6 / l3 43 564172 absorption structure. The specific degree of suction intensity will depend on the specific flow characteristics of the forming chamber (171). Obviously, the known short and repeated trial and error method can be used to find the ideal suction intensity. The density of the absorbent structure (101) before activation of the linking fibers is important for controlling the desired functional properties of the subsequently stabilized absorbent structure. Thereafter, the drum (137) carrying the absorbent structure (101) leaves the forming chamber (171) through the opening (175) to the cutting system (271) (as shown in figures 5 and 6), where the absorbent structure has more thickness than the thickness Can be trimmed and removed to a predetermined level. The cutting system (271) includes a cutting room (273) and a cutting roller (275) in the cutting room. The cutting roller (275) grinds away excess fibrous material from the absorbent structure (101), and the removed material is conveyed away from the cutting chamber (273) by a suitable drainage duct known in the art. For example, if desired, the removed fibrous material can be recycled back to the forming chamber (171) or the fiberizing machine (Π9). In addition, the cutting rollers (π) can be rearranged and redistributed in the machine direction (123) and / or the machine direction (125) of the absorbent structure (125). The cutting wheels (275) can be rotated The system is operatively connected and coupled with a shaft member (not shown) as shown, and is driven by a suitable system (not shown). The drive system may include any conventional lambda device such as a dedicated motor, or a Couplings, gears, or other transmissions that are operatively connected to a motor or drive mechanism used to rotate the forming cymbal. The cutting system 提供 can provide a traditional tailoring_removal or redistribution that has been formed on the forming surface (135) The excess thickness of the absorbent structure (101) above. The cutting operation can cause the absorbent structure to contact the cutting roller (275) to produce-the main surface-the free surface side (193) in the embodiment shown has the desired Contoured absorption structure (jOl). For example, the cutting roller (275) can be designed to provide a substantially flat surface along the absorbent structure (a cutting surface called 1), or can optionally be designed to provide an uneven surface. The cutting shaft (275) The handle surface (丨 35) is scaled, and the drum is forwarded by cutting. ^ The cutting roller (275) of the illustrated embodiment rotates clockwise and opposite to the direction of rotation of the drum (137). Or 'Cut Roller _ can also rotate with the forming surface of the forming drum 〇37): Regardless of the situation, the rotation direction of the cutting roller 应 should be selected appropriately to form a Kaihan absorption structure (1〇1) The contact surface provides effective cutting. In a similar method, any other suitable cutting mechanism can be used instead of the cutting system _ to provide fiber absorptive structures by absorbing, ". And the relative movement between the cutting mechanism ⑽) to provide cutting ΕΛΡΑΤΕΝΤΝPK -001 〇8 \ 〇831 \ pk-001-0831 -1 doc2003 / 6/13 44 564172 cutting or abrasion effect. After the cutting operation, the forming surface portion forming the absorbent structure (101) will be moved to the forming chamber ( 171) The release area of the outer device (121). In the release area, the absorbent structure (101) is sucked from the forming surface (135) onto a transport device (281) as shown in the fifth and sixth figures. This release can be assisted by using the air pressure inside the drum (137). The transport device (281) receives the formed absorption structure (101) of the forming drum (137) and transports the absorption structure to a collection area or a location for further Processing (not shown). For example, suitable transportation devices may include conveyor belts, air drums, transfer rollers, electromagnetic suspension transportation devices, fluid suspension transportation devices, etc., and combinations of these devices. In the illustrated embodiment, , Transportation equipment (281) Includes an endless conveyor belt (283) surrounding a roller (285). An empty suction box (287) is positioned under the conveyor belt (283) to suck the absorbent structure (101) off the forming surface. Transport The belt (283) is porous, and the hollow box (287) forms a full state at the position of the conveyor belt near the forming surface, so that the hollow state in the empty box can act on the absorbing structure (101) on the forming surface (135). The removal of the absorbent structure (101) from the forming surface (135) is also accomplished by the weight of the absorbent structure, centrifugal force, mechanical injection, positive pressure or a combination of these methods, or other suitable methods without departing from the present invention. For example, in the illustrated embodiment, the absorption structures (101) leaving the forming chamber are connected end-to-end to form a fabric or a series of absorption structures, each of which has a selected shape and It roughly corresponds to the corresponding forming member (201) used to form each individual absorbing member. Referring now to the fifth figure, when the pre-stabilized absorbing structure (101) is transferred from the forming surface (135) to the transport device (281), each Absorbent structure (304), wherein the connecting fibers are activated to form internal fiber connections within the absorption structure. In one embodiment, the connection activation system (304) includes an activation chamber (3) through which each absorption structure (101) passes. 〇6), and a generator (308) to radiate electromagnetic energy in the activation chamber when each absorption structure passes through the activation chamber. For example, a suitable microwave generator can provide a sufficient microwave energy and guide this energy Via a suitable waveguide (310) to the activation chamber (306). In one embodiment, the electromagnetic energy may be at least 0.3 RF amount of radio frequency (RF). Alternatively, the frequency is at least 300 MHz, and optionally at least 850 MHz. In other respects, the maximum chirp of this frequency may be 300 MHz, or more. Alternatively, the frequency can be up to 30,000 MHz 'or optionally up to 2600 MHz. In a specific embodiment, the wireless E: \ PATENT \ PK-001 08 \ 083 l \ pk-001 .00831 -1 doc2003 / 6/13 45 564172 is ideally 27 MHz. In another embodiment, the electromagnetic energy may be microwave energy, which ranges from 915 MHz to 2450 MHz. In the special-foot arrangement, electromagnetic energy can selectively heat the bonding fibers to a temperature higher than the melting temperature of the bonding fibers. Buttons, fusion bonding fibers can be made into knots and selectively connected to absorbent fibers, superabsorbent materials and / or other bonding fibers within the absorbent structure. The linking fibers can also be substantially activated without heating the entire absorbent structure (101). In a particular aspect, the linking fibers can be activated quickly, but can avoid excessive heating of the absorbent structure (101). Heating and thawing the binding fibers in the activated absorbent structure (101) can be achieved by any available effective mechanism. For example, electromagnetic energy can heat water vapor present in the absorption structure (101), and heated steam can selectively melt the connecting fibers. In another aspect, the machine can be absorbed by the linking fiber 'and the absorbed energy can selectively heat and melt the linking fiber. The total residence time of the absorbent structure (101) in the activation chamber (306) can provide a unique efficient activation period. In a specific aspect, the activation period is at least 2000 seconds. Alternatively, the activation period may be at least 0.05 seconds, and may also be at least 0.001 seconds. In other aspects, the activation period can be up to 3 seconds. Alternatively, the activation period can be 2 seconds or 1.5 seconds. The activation chamber (304) may be a conditioned space in which electromagnetic energy can generate an effective and continuous wave. In a particular aspect, the activation chamber (304) can be designed as a resonance chamber. A suitable device for a resonant activation chamber system is disclosed in U.S. Patent No. 5,536,921, issued by Hedrick et al. On July 16, 1996, entitled "System for Providing Microwave Energy to Sheet Materials," (system FORAPPLYING MICROWAVE ENERGY IN SHEET-LIKE MATERIAL); and U.S. Patent No. 59162403 issued by Brandon et al. On June 6, 1999, entitled "Composite Materials with Elastic Regions and Methods of Making them," (coppsite materia; l WITH ELASTICIZED PORTIONS AND A METHOD OF MAKINGTHE SAME). These documents are incorporated herein by reference in a form incompatible with the present invention. Another suitable activation system for activating binding fibers is disclosed in U.S. Patent Application Serial No. 10 / U37385, filed December 20, 2001, entitled "Apparatus and Method for Manufacturing Stable Absorbent Materials on the Line," (MethOd and Apparatus for Making On-Line Stabilized Absorbent Materials) 〇 After heating the bonding fibers, the absorption structure (101) leaving the activation chamber (304) can also be cooled or treated. A cooling system can be used to cool the absorption structure (101). The cooling system includes : Cold gas ΕΛΡΑΤΕΝΉΡΚ-ΟΟΙ 〇8 \ 〇831, {Λ · 〇〇1-083! .Ϊ́ £ ΐ〇 <; 2003/6/13 46 body, cold; east air, radiation cooling, air cooling, ambient air cooling, etc., and a combination of these methods. As shown in the fifth figure, the cooling system may include a refrigerated gas supply hood (321), an air transport device (323), an air box (325), and a cooler or other cooler element. Cooler element (327): Provides the appropriate coolant to the heat exchanger (329), and the bellows allows air to circulate through the heat exchanger to cool it. The cooled air can be directed to the fresh air supply) and onto the absorption structure (101). The air is then drawn out of the supply hood (321) to circulate through the heat exchanger (34) again. In a special aspect, the absorption structure (101) can be cooled to a set temperature, which is lower than the melting temperature of the material. On the other hand, the absorption junction is called to be within the selected downflow setting distance of the activation chamber (deletion), and can be cooled to no more than 勘. c temperature. In a further step, the absorption structure (101) within the selected set distance can be cooled to a temperature not exceeding U 叱. Therefore, after the absorption structure (101) is exposed to the high-fresh electromagnetic energy of the activation chamber (gang), the set distance can be measured. In a specific aspect, the set distance may have a minimum 値 of a5 m. Alternatively, the set distance may be at least 0.75 m, or at least 丨 m. On the other hand, the maximum distance i is set to 30 m or the distance between sighs may not exceed 20 m or ，. On the other hand, the increased portion of the heated absorption structure (101) can be cooled to a set desired temperature within a specific time. It can be determined by the time of the trip plus the activation room. Therefore, when the high-frequency electromagnetic energy in the activation structure (3G4) of the absorption structure is recorded, the farm can be measured. In particular, the minimum time for setting the time is a leap second. Alternatively, the interval may be at least _5 seconds, and may be at least 0 seconds.
