singeing

Singeing, also known as gassing, is a textile finishing process used to create a smooth surface on yarns and fabrics. It involves burning off protruding fibers and fuzz by passing the material over a gas flame or heated copper plates. This is done quickly enough to remove the loose fibers without scorching or burning the main material.1

Singeing is typically followed by passing the treated material over a wet surface to extinguish any lingering embers. This process enhances the appearance of the fabric, making it more acceptable to consumers by removing the fuzzy texture that can result from weaving or knitting. The term "singed" means to be lightly or superficially burned, often on the edges.12
