The material used in yarn and how they are put together greatly affects the finished yarn and fabric. Here you will learn about three yarn characteristics and how they affect the yarn. Filament fibers are those fibers which are long enough to be a yarn by themself and are usually measured in yards or even miles.
Most filament fibers are synthetic fibers such as polyester and rayon.
These fibers can be extruded from machines in infinite lengths. Silk is the only natural filament fiber since unraveled cocoons can yeild up to 3000 yards of fiber. Filament fibers can be monofilament with a single fiber or they can be twisted together to form multifilament yarns. Staple The other type of fiber used in making yarn is Staple Fibers. Staple Fibers are short fibers which must be made into yarn in order to be used.
