Viscose fiber is first put into industrial production of chemical fibers, mainly from natural cellulose cotton or wood pulp as raw material, alkali, inanimate, the processes of yellow yellow made of soluble cellulose ester, and then dissolved in dilute lye made of viscose, made by wet spinning and cellulose fiber, the basic component is cellulose. Of the 12 major textile fiber, viscose fiber moisture content and the most human skin physiology, not only smooth and cool, breathable, antistatic, stain bright features, and has excellent drape and silk-like luster, high heat and light stability, strength and depth to meet the needs of the overwhelming majority of prime textiles. Because good moisture absorption, comfort, excellent spinnability, drape well, often with cotton, wool, or various synthetic fibers, spinning pay for various types of clothing and decorative textiles.
