Viscose (viscose) is a generic term for viscose. It is further divided into viscose filament and viscose staple. The viscose fiber is a cellulose fiber produced by using cotton or other natural fibers as raw materials, and among 12 main textile fibers, the moisture content of the viscose fiber is most in line with the physiological requirements of human skin, and the viscose fiber has the characteristics of smoothness, coolness, air permeability, static resistance, gorgeous dyeing and the like.
