Viscose fiber is made of purified cellulose and made of specially processed wood pulp. Viscose fiber is very similar to cotton and silk. It is a delicate and soft material commonly used in T-shirts, tunics, shirts and dresses, all of which contain cellulose. There are two types of fibers: natural (cotton, wool, and silk); and man-made products synthesized from petrochemical products (nylon and polyester). The raw material for viscose is cellulose, which is mechanically or chemically decomposed and reorganized into fibers. In fact, viscose seems to be somewhere in between, but it is generally believed that viscose fiber is natural. Viscose fiber is obtained through special wood processing. Viscose fiber is made of wood pulp. Viscose is a viscous organic liquid used to make rayon and cellophane. Cellulose from wood fiber or cotton fiber is treated with sodium hydroxide and then mixed with carbon disulfide to form cellulose xanthate, which is dissolved in more sodium hydroxide. Viscose ya...
