Paper making grade chitosan has relatively lenient requirements for purity, placing greater emphasis on compatibility and functional effects with pulp fibers. Paper making grade chitosan can utilize the active groups in its molecules to form stable bonds with pulp fibers, enhancing the inter-fiber binding force. This, in turn, improves key paper properties such as strength and durability. Simultaneously, it can also assist in improving paper retention rate, drainage, and surface characteristics. It is a specialized additive for the papermaking process that combines functionality and adaptability.
When chitosan comes into contact with pulp fibers, active groups in its molecules, such as amino and hydroxyl groups, interact with functional groups on the fiber surface. This leads to the formation of stable hydrogen bonding connections between fibers. This bonding can significantly enhance the binding force between fibers, thereby increasing paper strength and durability. This makes the paper more resistant to pulling and less prone to breakage during use, effectively extending the paper’s service life.

Application of Paper Making Grade Chitosan
1. Chitosan Used In Paper Making As Water Retention Agent:
Chitosan has good water retention properties and can act as a water retention agent during paper production. It can adsorb moisture on fibers and fillers, preventing the paper from drying prematurely during the manufacturing process and improving paper quality.
2.Composite Application of Chitosan with Anionic Substances In Paper Making:
Chitosan can form complexes with anionic substances (such as starch) for surface coating of paper. This complex can increase the surface strength and water resistance of the paper, improving its printability and ink fixation.
3. Chitosan Used In Paper Making as a Resin Modifier:
Chitosan can react with resins (such as polyvinyl alcohol) to form chitosan resin modifiers. This modifier can increase paper strength, durability, and water resistance, improving paper quality.
The application of paper making grade chitosan is mainly through enhancing the wet strength, water retention properties, and surface performance of paper, improving the physical properties and printability of paper, and increasing paper quality and service life.
As a professional chitosan manufacturer and supplier, Tianya Chemical always adheres to the principle of customer – first. We provide not only high – quality paper making grade chitosan but also professional technical support and after – sales service. If you are looking for a reliable partner for paper making grade chitosan, Tianya Chemical is your best choice.
