Document Summary
A yarn is a continuous strand of textile fibers, filaments, or materials in a form suitable for knitting, weaving, or otherwise intertwining to form a textile fabric. Yarn classification: classified by their types: filament yarns are made from manufactured fibers by extruding a polymer solution through a spinneret and solidifying it in fiber form. The grouping of the filament with the addition of twist creates the filament yarn. (except for silk: staple yarns are made up of short fibers that are twisted together. Throwing, originally a process for twisting silk filament, evolved into the twisting of manufactured fibers and then into texturing. Throwing provides the fabricator with the specific yarn needed for a particular product. They are uniform as they come from the spinneret. No protruding ends, so they don"t lint or pill. Very-high-twist yarns, like crepe yarns, reduce filament luster. The fabrics made from them shed soil.
