Pre treatment of textiles In the production process of textiles, caustic soda is commonly used in the pre-treatment stage. It can remove natural impurities such as wax, pectin, cellulose, etc. from natural fibers such as cotton and hemp, and this process is called degreasing. The use of caustic soda

The main uses in the papermaking industry1. Pulp productionIn the production process of pulp, caustic soda is mainly used for the preparation of chemical pulp. By treating wood with caustic soda, lignin can be effectively separated from cellulose, and this process is called delignification. The pulp
