A cationic fixing agent is a chemical compound primarily used in the textile industry to enhance the color fixation and fastness of dyes on fabrics. These agents are positively charged (cationic), allowing them to form strong bonds with the negatively charged dye molecules, improving the durability and intensity of the color. Cationic fixing agents are also used to improve the wash fastness, light fastness, and abrasion resistance of dyed fabrics, making them more resistant to fading.
