Application of Hyperbranched Polymer with Terminal Amino in Dyeing Process of Microfiber Synthetic Leather

Article Preview

Abstract:

Hyperbranched polymer with different contents of terminal amino group synthesized with succinic anhydride and DETA through the molten polymerization method was used in the dying process of microfiber synthetic leather substrate as color fixing agent. The effect on dye-uptake, surface chromas of microfiber synthetic leather substrate, wet and dry rub fastness was discussed. The result indicated that when the dosage of hyperbranched polymer with 5.85% terminal amino groups was 0.8%, the dye uptake rate was 92.92% and surface chroma was the best, the wet and dry rub fastness of microfiber synthetic leather substrate were almost unchanged.
