Aromatic Polymer Textile Auxiliary Agents High Molecular Weight For Acid Dye

High-Molecular-Weight Aromatic Polymer Textile Auxiliary Dyeing Agent For Acid Dye

Formaldehyde-free fixing agent LT-361

The formaldehyde free fixing agent LT-361 belongs to the cationic polymer of polyamine, which can form a water-fast macromolecular compound with dyestuff, thus to improve the color fastness to washing and rubbing resistance. It is suitable for dyeing or printing with reactive and direct dyes such as cotton, linen, viscose, etc.

Technical Specification
