Types of yarn: staple (short fibers) or, single (one strand) or, simple (same appearance along length) or, filament (continuous filaments, plied (two or more strands, twisted) *cord (cabled: complex (variable appearance along length) Filament yarns may be: flat or texturized, a t-shirt would probably be knit from a simple, single, staple yarn, fabric for a slip would probably be knit from a flat, simple, single. Filament yarn: cord (top), single (center), and ply (bottom) yarns. Examples: staple fibers twisted together, filament fibers laid side by side, with some twist applied, single filament fiber, strips made by lengthwise division of a sheet of material.
