Different intensity of cationic tertiary amine type organic-silicone modified cationic waterborne polyurethane reactive dye wet-rubbing fastness improver was prepared. The influences of dosage of polyure-thane cationic monomer on emulsion stability and the main application properties were studied. The results showed that: moderate cationic intensity in waterborne polyurethane polymer scaffold could effectively im-prove the adsorption of cotton fiber and anionic group in dye molecules. Comprehensive consideration of the control ability of the macromolecule assistant preparation, the stability of the emulsion and the main applica-tion properties, the best cationic polymerization monomer dosage was determined as 8.0%. The wet rubbing fastness of the treated reactive dyed fabric was improved by 1 degree.
