Description

The reaction was invented viscose of the cellulose in the U. K. in 1982. It is produced approximately 4 million tons now in the world. It is as follows about the manufacturing method of the viscose rayon. Dissolving pulp is used for the cellulose materials of viscose. Pulp is immersed in sodium hydroxide solution and it is made alkali cellulose. Subsequently, carbon disulfide is made to react to alkali cellulose, and cellulose xanthate is produced. And a dilute alkali solution is added to cellulose xanthate, and it is made to dissolve in it. This solution is called viscose.<BR>Viscose rayon is produced by carrying out solidification reproduction of this viscose.<BR>Viscose rayon is used for clothing, industrial materials, and paper making. Moreover, functional rayon with a special function is produced by adding functional materials to viscose.
