Continuous filament yarns include natural silk as well as manufactured filaments extruded from synthetic polymers(e.g. polyester, nylon, polypropylene) or modified natural polymers(e.g. viscose rayon). Such filaments are twisted or entangled to form filament yarns. They posses excellent strength and uniformity, as well as possibility for fineness but poor hand, bulkiness and covering power.
Textured filament yarns can be further separated into several types. The more commonly used are false-twist textured, air-jet textured and hot-fluid textured yarns. They posses good stretchability and covering power, excellent strength and uniformity, but poor hand.
