Alkali Cellulose

The product of the interaction of purified cellulose. Note: in the manufacturing of viscose fibres, the cellulose may be cotton linters or wood-pulp. After pressing, alkali-cellulose usually contains approximately 30% of cellulose and 15% of sodium hydroxide, the remainder being water. During the steeping of the cellulose in sodium hydroxide (18-20% wjw) to form the alkali-cellulose, soluble impurities, including soluble cellulose, are removed.
