Refers to natural or synthetic cut fibers. The work “staple” is used by the textile industry to differentiate cut fibers from continuous filament fibers, such as that used in the spunlaid process. Synthetic staple fibers used in the needlepunched process are generally about 3.8-4.8 cm in length. The fiber lengths of natural fibers, which include wool, cotton, choir, jute and several others, vary considerably.
