Papermaking

In the papermaking industry, cationic chitosan has been widely used in various papermaking additives and plays a pivotal role in making excellent paper. 

1. Linear soluble polymer has larger molecular mass, high film formation ability and enough adhesive strength for fibre; 

2. Highly compatible with cellulose, without damaging the hydrogen bonds between fibre molecules;  

3. The functional groups can fully contact the paper fibre and can achieve fast integration with the paper fibre via ionic bond and hydrogen bond;

4. A nontoxic and biodegradable natural product.
