Cellulose used for textile and papermaking all over the world reaches more than 8 million tons every year. Cellulose is an important raw material for paper making.

There are two main uses in the paper industry: pulp addition and surface sizing. The amount of pulp addition is about 3% to 5%, which can increase the longitudinal and transverse tension of paper by 30% to 50%, and plays a good role in the use and writing of paper. The surface sizing, especially the water retaining agent on the coated paper, is a product that cannot be replaced by other adhesives. It plays a good role in the flatness and smoothness of the paper.
