Abstract

Improvements in the manufacture of the viscose, characterized in effecting the mercerization by immersing the pulp of the material in a solution of caustic soda containing 0.05 to 5.0% by weight of sodium cincate as well as zinc oxide and in in the case of 0.05 to 5.0% by weight of sodium aluminate, xanthogenation is carried out by adding alkylene cellulose of 15 to 29% by weight of carbon disulfide with respect to cellulose, for 30 to 90 minutes., controlling the temperature, and finally carry out the dissolution of the xanthate by adding the alkali and water solution.
