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.

The process is usually to pass one or both sides of a fabric over a gas flame to burn off the protruding fibres. Other methods include infra-red or heat for thermoplastic fibers. Singeing of yarns is called "gassing". It is usually the first step after weaving or knitting, though the fabric may be brushed first to raise the surface fibres.

Cellulose fibres such as cotton are easily singed because the protruding fibers burn to a light ash which is easily removed. Thermoplastic fibres are harder to singe because they melt and form hard residues on the fabric surface.
