Viscose is produces from wood pulp. Viscose is a viscous organic liquid used to make rayon and cellophane. Cellulose from wood or cotton fibers is treated with sodium hydroxide, and then mixed with carbon disulfide to form cellulose xanthate, which is dissolved in more sodium hydroxide.
The resulting viscose is extruded into an acid bath either through a slit to make cellophane, or through a spinneret to make rayon. The acid converts the viscose back into cellulose. It is used widely & in huge demands owing to its special characteristics like: High strength, Low moisture retention and Best suitable for highly developed machines that are used in textile industry.
