Virgin Polyester Staple Fiber is a kind of chemical fiber. The fiber length is about 38mm, and the fineness is 1.5D. Chemical fibers are divided into polyester, acrylic, polyvinyl chloride, spandex, vinylon, polypropylene, aramid and other categories according to their chemical composition. From the shape, it can be divided into filament, medium and long fiber (generally 64mm in length), and short fiber (38mm in majority). Polyester staple fiber can be spun alone or blended with various cotton fibers or staple fibers such as cotton to form yarn. It is the most used chemical fiber in my country's textile industry.
