Document Summary
Continuous length of fibers in a form suitable for weaving, knitting, braiding or otherwise covering to fabric. Is a product for joining parts and components. Used as a sewing thread to join fabric together. Fiber length is used to broadly divide yarns into: Spun yarns: made from short or staple fibers. Yarn processing methods for spun yarns are very different from those of filament yarns. Spun yarns: formed from short (staple- hairy), irregular or regular lengths of fibers held together by twist. Filament yarns: formed from single or multiple (intermingled) continuous strand(s) of material. Fancy: an irregular yarn is deliberately produced for special effects. Multifilament yarn: filament fibers held together with minimal twist. Formed from a center (core) material wrapped by either spun or filament yarns. Formed from a center (core) material wrapped by fibers. Two-ply, tweed yarn with small tufts of fibers that are inserted when the yarn is twisted.
