Description

DETAILED DESCRIPTION OF THE INVENTION

TECHNICAL FIELD [0001] The present invention generally relates to material structures in absorbent articles for everyday items such as diapers, toilet training pants, absorbent underwear, adult incontinence products, bandages, sanitary products, and the like.

BACKGROUND OF THE INVENTION Daily absorbent products include feminine hygiene products such as diapers, toilet training pants, sanitary napkins, panty liners, and tampons, incontinence clothing and equipment,
Including articles such as bandages. Most basic designs of such articles generally include a bodyside liner, an outer cover, and an absorbent core disposed between the bodyside liner and the outer cover. Generally, the bodyside liner and the outer cover are sealed around the outer periphery to enclose the absorbent core, allowing the liquid contained in the absorbent core to be captured and retained. Other ingredients may also be included depending on the design of the particular commodity. Thus, the product has elastic side panels, fluid storage flaps,
It may include a separate layer of coupling device and fluid transfer or retention material.

[0003] The everyday items described above have been composed of separately formed materials, which are joined together to form a laminate. In such cases, the boundaries between adjacent layers are relatively sharp and are often marked by an adhesive used to hold the layers together to create a laminate. Producing separate adhesives that bond together to form each layer and laminate is an expensive procedure that requires many different parts of the production equipment. This manufacturing method results in everyday materials having sharp boundaries between each layer at the intermediate plane or boundary, resulting in reduced fluid transfer between adjacent layers.

[0004] It is an object of the present invention to create materials for everyday use that do not require many manufacturing steps. Mixing to improve fluid transfer between adjacent layers,
It is yet another object to create everyday materials with interlaced fibers, with adjacent layers having unclear boundaries.

DISCLOSURE OF THE INVENTION The object of the present invention is to provide a body side liner made of synthetic fiber or binder having a basis weight of about 10 to about 100 gsm, a density of about 0.05 to about 0.5 g / cc, and a basis weight. Is about 50 to about
250 gsm, having a density of about 0.05 to about 0.5 g / cc, a liquid retaining layer of synthetic fibers, binder or natural fibers, wherein the boundary between two adjacent fiber layers is unclear, The fibers at or near the surface of adjacent layers are significantly intermingled.

[0006] The material may optionally include a fluid distribution layer and a fluid transfer layer and a garment side liner. Another optional component includes a superabsorbent, an odor control component, and the layer may be embossed for appearance and fluid control.

(Definition) “Disposable” does not mean that it is discarded after use, washed and reused. The term “front and back” is not used throughout this specification to indicate where a garment is worn, but is used to determine a relationship with respect to the garment itself. By “hydrophilic” is meant a fiber or a surface of a fiber that is wetted by an aqueous solution that contacts the fiber. The degree of wetting of a material is described in terms of the contact angle and surface tension of the liquid and the material contained therein. Equipment and techniques suitable for measuring the humidity of a particular fiber material can be obtained with a Cahn SFA-222 surface force analyzer system or a system substantially equivalent thereto. Fibers with a contact angle of 90 ° or less, as measured with this system, are defined as wettable or hydrophilic, and fibers with a contact angle of 90 ° or more are defined as non-wettable or hydrophobic.

“Inner” and “outer” are laterally or longitudinally adjacent to or spaced apart from the center of the absorbent garment, in particular the longitudinal and lateral center of the absorbent garment. Means that

A layer, when used in the singular, has the dual meaning of a single element or multiple elements.

[0010] Liquid refers to a flowing non-particulate substance or material, which has the internal shape of a container into which it is poured or placed.

Liquid communication means that liquid can move from one layer to another, or from one location to another within one layer.

The terms “longitudinal” and “lateral” have the customary meaning. The longitudinal axis is in the plane of the article when the article is fully stretched flat, and is generally parallel to the water surface which divides the upright wearer into two halves when the article is worn. The transverse axis is in the plane of the article that is substantially perpendicular to the longitudinal axis. The illustrated article is longer in the longitudinal direction than in the lateral direction.

“Particles” in the context of the present invention means geometric forms such as spherical particles, fibers or strands, flat surfaces, rough surfaces, sheets, ribbons, strings, strands and the like.

“Spray,” and variations thereof, refers to any of particles that are sprayed through an orifice, nozzle, etc. by pressurization of a stream, swirl filament, or air or another gas, by gravity, or by centrifugal force. As forcing the liquid out. The spray can be continuous or discontinuous.

“Conjugate fiber” refers to at least two fibers extruded from a separate extruder.
Means one polymer but not spun to form one fiber.
Conjugate fibers are also referred to as multicomponent fibers or bicomponent fibers. The conjugate fibers are monocomponent fibers, but the polymers are generally different from each other. The polymer is organized into discrete zones that are substantially uniformly arranged across the cross-section of the conjugate fiber and extend continuously along the length of the conjugate fiber. The structure of such conjugate fibers may be, for example, a sea core structure in which one polymer is surrounded by another polymer, or a side-by-side structure, a pie structure, or an undersea island structure. The conjugate fiber is disclosed in U.S. Pat.
Nos. 108, 820; 5,336,552 to Strac et al. And 5,382,400 to Pike et al. For bicomponent fibers, the polymer is 75 / 25.5
It may be present at a ratio of 0/50, 25/75 or another desired ratio. The fibers are disclosed in U.S. Pat.No. 5,277, issued to Hongle et al., Which discloses fibers having an unusual shape.
No. 976, 5,069,970 and 5,057,368 to Lagman et al., All of which are incorporated herein by reference.

“Bicomponent fiber” refers to a fiber formed from at least two polymers extruded from the same extruder as a mixture. A mixture is defined as follows. Bicomponent fibers do not have the various polymer components organized in separate zones that are approximately constant over the king area of the fiber, and the various polymers are common along the entire length of the fiber. To form fibrils or raw fibrils that start and end irregularly instead. Bicomponent fibers are sometimes referred to as multicomponent fibers. Fibers of this general type are discussed, for example, in US Pat. No. 5,108,827 to Gesner. Bicomponent and bicomponent fibers are discussed in Text Polymer Blends and Bicomponent Fibers, pp. 273-277, by John A. Mason and Leslie H., published in 1976 by Plenum Press.

“Dry deposition” is a known method in which a fibrous nonwoven layer is formed. In a dry deposition process, bundles of fibrils having a length in the range of about 3 to about 19 millimeters (mm) are separated and flowed into an air supply, where they are deposited on a forming screen, usually with the help of a vacuum supply Is done. Irregularly deposited fibers are, for example, U.S. Pat.No. 4,005,957,
Nos. 4,388,056, 4,592,708, 4,598, 441, 4,674,996, 4,761,258, 4,764,325, 4,904,440, 4,908,175 and 5,

“Daily items” include diapers, toilet training pants, absorbent underwear, adult incontinence products,
Means love and feminine hygiene products.

“Women's hygiene product” means a sanitary napkin or pad.

“Target area” means the area or location of everyday products that the wearer normally excretes. Test Methods Material Caliper (Thickness) The caliper of the material is a thickness measurement, measured at 0.05 psi using a turret type bulk tester, in millimeters.

The density of the material is determined by dividing the weight per unit area of the sample (grams per square meter (gsm)) by the volume of the sample (millimeters (mm)) at a pressure of 68.9 Pascals and multiplying the result by 0.001. And converted to a value in grams / cubic centimeter (g / cc).

[Detailed description of the present invention]

Daily absorbent articles include items such as diapers, toilet training pants, feminine sanitary napkins, feminine hygiene products such as pantiliners and tampons, incontinence clothing and equipment, bandages and the like. The most basic design of all such articles includes a bodyside liner, an outer cover and an absorbent core disposed between the bodyside liner and the outer cover. Generally, the bodyside liner and outer cover are sealed around the perimeter to enclose the absorbent core, allowing the fluid contained within the absorbent core to be captured and retained. Other components may be included depending on the design of the particular daily absorbent article. Thus, the components may include such things as resilient side panels, fluid containment flaps, coupling devices and another layer of fluid transfer or retention material.

It can be seen that the description of the materials relating to the daily commodities is contained in the specification of the patent application filed on the same date by the Applicant with the reference number 13303.10. Case number
A discussion of the method of making the material of 13303.10 can be found in the applicant's specification, attorney docket 13817.

The present invention is a material for use in everyday products that is designed to create an unclear boundary or interface between adjacent fiber layers. Conventional everyday items are composed of separately formed materials and have been joined together to create a laminate. In such cases, the boundaries between adjacent fibers are relatively sharp and distinct, but are often marked by the presence of the adhesive used to hold the layers together to make the laminate.

The material of the present invention is preferably made according to a dry deposition process in which the fibers are suspended, conveyed in a gas stream, preferably air, and deposited on a substrate to form a layer. The material of the present invention is made from multiple layers and subsequently deposited. Continuous deposition of such materials is possible in a multi-bank dry process. In this process,
The fibrous layers are separated and stabilized separately, not only creating a laminate together, but one over the other. Of course, although all materials are stabilized by a given means, separate layers of the present invention need not be stabilized. Stabilization is achieved by using a binder, which, if thermally activated, obviously requires heat treatment of the material after fiber deposition.

The individual fiber layers of the material of the present invention have fibers that are intermixed and entangled with the fibers of the adjacent layers as a result of the dry process. Because of this aspect of the air lay and the usual absence of adhesion between adjacent layers, there is no sharp and unclear boundary or interface between adjacent layers.

[0027] The production of material by a multi-bank dry process is much more economical than the process of creating the separation layers and joining them together, which can reduce costs to the end consumer.

[0028] The material of the present invention has a body side layer and, optionally, a fluid transport layer, a fluid retaining layer, and a garment side layer. The material may have a distribution layer or another optional layer to provide a special function.

The body side layer is a body side liner or a top sheet. In the thickness direction of the article, the liner material is the layer to the wearer's skin, with the first layer in contact with the liquid, ie, the other waste from the wearer. The liner must be utilized to keep the wearer's skin away from the liquid held in the absorbent structure, and must be comfortable and soft and non-irritating.

The body-side liner has a basis weight of about 10.0 / square meter (gsm) to about 100 gsm, for example.
The density is from about 0.05 grams / cubic centimeter (g / cc) to about 0.5 g / cc. The bodyside liner is composed of synthetic fibers and about 90/10 to about 0/100 binder, more particularly about 50/50 to about 20/80, and more particularly about 30/70 binder.
Binder fibers that are not liquid binders are preferred, especially in these cases having a binder of 10 percent or more.

The bodyside liner can be treated with a selected amount of surfactant, such as about 0.28 percent Triton X-102 surfactant, or otherwise can be treated to provide desired levels of wettability and hydrophilicity. . If a surface treatment is used, it may be an internal additive or may be applied to the layer by conventional means such as spraying, brush coating, etc., before deposition of the next layer.

The fluid-retaining layer used in the present invention must absorb liquid from adjacent body-side layers in a controlled manner so that the liquid accumulates away from body contact. Suitable holding materials of the present application have a basis weight of about 50 to about 250 gsm and a density of about 0.05 to about 0.5 g.
Must be / cc. The holding material is composed of a binder, synthetic fibers and natural fibers. The binder is about 3 to 15 weight percent or, more specifically, about 1
Must be present in an effective amount of 0 weight percent. The synthetic and natural fibers, excluding the binder, may be present in a ratio of about 0/100 to about 50/50, more particularly, about 10/90 to 20/80, and more particularly, about 40/60. While the layers of the present invention may optionally include a superabsorbent, the fluid retaining layer is the most logical layer containing such components. This layer may contain from 0 to 85 weight percent superabsorbent and must be included as natural fibers in calculating the percentage of material present.

A particularly effective additive layer is the second retention layer, but multiple layers may be made in connection with the present invention. Such a second retention layer is sandwiched between the first retention layer and the garment-side liner and, except for the binder, comprises about 75% natural fiber and about 25% superabsorbent fiber in effective amounts. Including. As described above, the superabsorbent is considered to be a natural fiber in the proportion of the fiber in the layer, and excludes the binder to reduce the proportion of the synthetic fiber and the natural fiber in the layer.
Set to 0/100.

The clothing-side liner layer is referred to as a back sheet layer, and is a layer farthest from the wearer. The outer layer is typically formed from a thin thermoplastic film, such as a polyethylene film, and is substantially liquid impermeable. The outer cover functions to prevent body waste contained in the absorbent structure from wetting or soiling the wearer's clothes, bedding, or other materials that come into contact with everyday items. The outer cover has, for example, an initial thickness of about 0.5
It may be from mill (0.012 millimeters) to about 5.0 mils (0.12 millimeters), and the outer cover is preferably made as an integral part of the material of the present invention. In this case, the garment liner or outer cover should have a basis weight of about 10 to about 100 gsm and be composed of synthetic fibers and a binder in a ratio of about 50/50 to about 0/100.

[0035] The outer cover may be embossed or matted to provide a more aesthetic appearance. Another structure for the outer cover,
Includes woven or nonwoven fibrous webs configured or treated to provide the desired level of liquid impermeability, or laminates formed from woven or nonwoven and thermoplastic films. The outer cover may be made of a water vapor or gas permeable, porous gas-permeable material that can transmit water vapor or gas but is impermeable to liquid.
Breathability is achieved, for example, by using a filler in a film polymer formulation, extruding the filler / polymer formulation into the film, stretching the film sufficiently to create voids around the filler particles, and allowing the film to breathe. To give the polymer film. In general, the greater the filler used and the greater the extensibility, the greater the degree of air permeability. Even if it does, the function of the alignment member of the mechanical fastener is utilized, in which case, for example, a nonwoven fabric is the outer surface.

The optional fluid transfer layer is referred to as a surge layer and most commonly is in intimate liquid communication with and disposed between a bodyside liner and another layer such as a liquid distribution or retention layer. . The fluid transfer or surge layer is generally capable of passing fluid in the Z direction, ie, from the body side to the garment side. The surge layer is generally below the inside (unexposed) surface of the bodyside liner. The surge layer has a density of about 0.05 g / cc to about 0.5 g / cc and preferably has a basis weight of about 10 to about 100 gsm. The surge layer may be any fiber composed of synthetic fibers, binders, and natural fibers.The binder is present in an effective amount, and excluding the binder, the ratio of synthetic and natural fibers is about 40/60 to about 10/90. Exists in.

An optional distribution layer is interposed on the fluid retaining layer (towards the wearer) and must be able to move fluid from one point of initial deposition to the point where accumulation is desired.
Thus, in addition to being able to move the fluid in the Z direction, the fluid distribution layer is able to move the fluid in the X and Y directions. The distribution must be made at a possible rate so that the target excretion area, typically the crotch area, is ready for the next excretion. The time between excretions ranges from a few minutes to hours, and generally depends on the age of the wearer and the everyday items in question. In order to achieve the transport function, the distribution layer must have a high capillary tension value. Capillary tension in the dispensing material is simply measured by parallel vertical wicking of 8.5 g / l saline and must be greater than 15 cm. The wicking test is performed by placing one end of the material vertically in the saline, waiting for the solution to equilibrate, and measuring the height when this is reached. The distribution layer may be made from synthetic and natural fibers with a small amount of binder.

[0038] Synthetic fibers include those made from nylon, polyethylene ester, rayon, polyolefins such as polypropylene, lyocell regenerated cellulose, and synthetic fibers known in the art. Such synthetic fibers are conjugates, 2
The components and homopolymer staple fibers or fibers of another length, or may include such fibers having another type of fiber. Synthetic fibers may include cosmotropes to create the degradation described below.

The natural fibers include, for example, cellulose such as wood pulp and cotton. The pulp contains standard soft wood fluff grades, such as Kimberly-Clark Coosamil CR-1654, and the bulky formaldehyde-free pulp (GBAFfF) available from Waferwather, WA Tacoma, for improved wet modulus. Cross-linked southern softwood fibers, and chemically cross-linked pulp fibers such as Wirehausa NHB416. HBAFF provides dry and wet stiffness and elasticity to the fiber,

There is increasing interest in creating everyday products that are flushable, ie, discardable in common toilets, and that are safe for spoilage or municipal waste management systems. One way to increase the biodegradability of everyday products is to create products that break off rapidly in the presence of such systems. There are a number of mechanisms that can produce this result, but most are inappropriate and unreliable, which results in the product failing in an inappropriate number or even an inordinate amount of time before it leaves Will occur.

One mechanism that can be used to induce water biodegradability in an appropriate time is ion sensitivity, where ion is the conventional meaning of an atom or a molecularly attached atomic group,
It has a negative or positive charge after gaining or losing one or more electrons. Certain polymers include an acid group (R-COO-) component that is held together by hydrogen bonding. In the dry state, these polymers remain solid. In aqueous solutions having a relatively high ionic concentration, such as urine, the polymer remains relatively intact. But,
If the same polymer is later exposed to large amounts of water at a reduced ionic concentration, as seen in toilet bowls, the ionic concentration will decrease and hydrogen bonds will begin to break down.
When this occurs, the polymer itself begins to degrade in water. Materials with these properties are known as Kosmotropes. See, for example, U.S. Pat. No. 4,4,19,403 to Barona, which the present invention incorporates by reference.

In the conjugate fiber, for example, a first component polymer that is stable in a high ionic strength solution environment (eg, urine and menstruation in infants or adults) is obtained by Eastman Chemical Company, Tennessee Kingsport. Such a sulfated polyester code is AQ29, AQ38, or AQ55. Eastman's AQ38 polymer has 89 mole percent diethylene isophthalate and 22 mole percent 1,4-
Consists of cyclohexanedimethanol. It has a nominal molecular weight of 14000 daltons, an acid of 2 or less, a hydroxyl of 10 or less, and a glass transition temperature of 38 ° C. Other examples are mixtures of poly (vinyl alcohol), copolymers of poly (vinyl alcohol) mixed with polyacrylic or methacrylic acid, polyvinyl methyl ether mixed with polyacrylic or methacrylic acid. Eastman polymers are stable in high ionic solution environments, but are rapidly degraded in toilet water during the flushing (volume of water) process. Eastman polymers are compatible with second component polymers in the higher melting temperature range, such as polyethylene.

Another first component polymer that is stable at high ionic concentrations includes an induced water-dispersed polymer. This means that when the first component of the conjugate fiber is exposed to an inducing component, such as sulfate or chloride, at a first concentration level found in, for example, normal tap water, the polymer of the first component will be reduced to 30%. Disperse or decompose within minutes. However, when the first component of the conjugate fiber is exposed to the same trigger component at a second higher concentration level commonly found in human fluids such as urine or menstruation in infants or adults, the first component Polymer remains stable and does not disperse. Suitable examples of such first components include copolymers such as water-dispersible polyester or polyamide polymers or copolyester polymers available from the National Starch and Chemical Company under product registrations 70-4395, 70-442. Conjugate fibers having a first component comprising a triggered water-dispersible polymer do not respond to the presence of certain triggering components at the concentration levels found in urine or menstruation, but excessive tap water as found in toilet bowls Reacts and disperses within 30 minutes in the presence of the same trigger component at different low concentration levels commonly found in Thus, a fibrous web formed from or incorporating an induced water-soluble polymer is excreted in normal tap water when dispensed with human fluids such as urine or menstruation, with no effect on dispersibility. And the conjugate fiber dispersion
It tends to decompose as a component.

Further, it is preferable that all materials are embossed, preferably from the human body liner side. The embossing is light enough to emboss only the bodyside liner or includes a fluid retaining layer with optional fluid transport and distribution layers. The embossing pattern can be selected to maximize material density, enhance fluid uptake and dispersion throughout the product, and enhance fluid dispersion along the front-rear axis. Embossing can be used to give the wearer a visual signal that product capacity is approaching saturation and must be discarded, as well as providing aesthetic benefits. Examples of suitable emboss patterns are shown in the figure. FIG. 1 shows an embossing pattern of a daily product called a sine wave pattern, and FIG. 2 shows an embossing process of a daily product called a shell pattern.

While only a few examples of the present invention have been described in detail, those skilled in the art can make exemplary implementations without departing from the novel teachings and advantages of the present invention. You will see that. Thus, all modifications are included within the scope of the present invention as defined in the appended claims. In the claims, the claims following the means and functions are set forth in the present invention as implementing the described functions, not structural equivalents but equivalent structures. The pawls and screws are not structurally equivalent in that the pawls utilize a cylindrical surface to join the wooden pattern together and the screws utilize a helical surface, but are not uniform in an environment that joins the wooden pattern. Structure.
