===Singeing===
<br />
'''The process of singeing is carried out for the purpose of removing the loose hairy fibres protruding from the surface of the cloth, thereby giving it a smooth, even and clean looking face.'''<br />
Singeing is an essential process for the goods or textile material which will be subjected to mercerizing, dyeing and of course printing to obtain best results from these processes.
<br />
 
Singeing is designed to burn off the surface fibres from the fabric to produce smoothness. The fabric passes over brushes to raise the fibres, then passes over a plate heated by gas flames. In the textile industry, loose fibres protruding on the surface of textile goods are singed to remove them. When done to fabrics containing cotton, this results in increased wettability, better dyeing characteristics, improved reflection, no "frosty" appearance, a smoother surface, better clarity in printing, improved visibility of the fabric structure, less pilling and decreased contamination through removal of fluff and lint.<br />
'''Singeing machine can be of three types, 1. Plate Singeing, 2. Roller Singeing, 3. Gas Singeing.'''<br />
'''Among them Gas Singeing Machine is widely used in the textile industry like Unifill Textile, Bangladesh, Tania Textile Division, Bangladesh.'''
In gas singeing machine, fire flame comes into direct contact to the fabric and burn the the protruding fibre.'''Flame height and fabric speed is the main concern to minimize the fabric damage. '''
