Formaldehyde Free Fixing Agent Rx-8175

Formaldehyde free fixing agent RX-8175 is a polyamine type high molecular composite polymer with small molecular weight and good hydrophilicity. It is easier to penetrate into the fiber and form an ionic bond with the anionic groups in the dye molecules, so as to effectively improve the color fastness. It is suitable for fixing process of fabrics after dyeing or printing with reactive dyes or direct dyes, can significantly improve the fastness to washing, perspiration and soaking, and has little impact on the fastness to sunlight and perspiration.
