It is commonly referred to simply as viscose, which was one of the first brands to the product. Viscose was invented by the English chemist Cross and Bevan at the English Viscose Company in England in the 1900s. Since then, viscose has become one of the most common types of rayon and one of the most important man-made fibers worldwide. Production Process of Viscose Fiber The production of viscose fiber begins with dissolving wood pulp or cotton linters in a solution containing caustic soda and carbon disulfide. This results in cellulose xanthate, which when treated with dilute sulfuric acid forms a viscous solution. The solution passes through spinnerets into a bath of sulfuric acid and sodium sulfate to regenerate almost pure cellulose fibers. The Viscose Staple Fiber are washed, bleached, dried and cut or crimped...
