Viscose Rayon

Viscose pulps are high purity pulps that are mixed with sodium hydroxide to form a material called alkali cellulose and then reacted in a mixture of sodium hydroxide and carbon disulfide. This resulting substance, called cellulose xanthenes is further reacted with a mineral acid to regenerate pure cellulose. The regenerated cellulose can be a fiber, like rayon, or other forms, like the film cellophane.
