Principle of Cationic Modifier
Release time:
2024-03-08
The principle of the cationic modifier is mainly related to the electrostatic attraction between the cation and the negatively charged group. During the treatment process, the cationic modifier molecules enter the interior of the substrate, and their positive charges attract each other with the negative charges on the surface of the substrate, forming ionic bonds or hydrogen bonds, thereby improving the performance of the material, enhancing its adsorption capacity and adhesion, and improving Its chemical stability.

The cationic modifier is a polymer compound with a positive charge in the molecule, which can react with a negatively charged monomer, convert it into a positively charged polymer, and introduce a positive charge into it. Chemically, cationic modifiers are defined as a class of organic compounds with cationic properties.
Adding a cationic modifier to the coating can enhance the adhesion between the coating and the substrate, improve the abrasion resistance and scratch resistance of the coating, and also provide special functions such as antistatic and antibacterial.
In addition, the cationic modifier can also be used to improve the surface properties of the fiber, for example, by neutralizing the negative charge on the surface of the fiber, so that the surface charge of the fiber becomes positive, thereby improving the attraction between the fibers and improving the softness and water absorption of cotton.
