摘　　要：采用端氨基小分子染料活性蓝与异氰酸酯、多元醇等反应制备了一种高分子染料BPD,将制备的高分子染料用于透明皮革染色研究。研究表明:高分子染料染色透明皮革拥有较好的耐迁移、耐擦色牢度,耐迁移可达到4~5级,耐干擦色牢度为5级,耐湿擦色牢度可达4~5级;高分子染料的引入可以提高皮透明皮革的力学性能,当高分子染料用量为0.14%时,透明皮革抗张强度和撕裂强度可分别提高2.7倍和2.4倍;高分子染料对透明皮革透水汽性能影响较小。A polymer dye was prepared by the reaction of reactive blue 4 with isocyanate and polyol, and the prepared polymer dye was used for transparent leather dyeing research. The results show that transparent leather dyed with polymer dyes has better migration resistance and color fastness to rubbing, migration resistance can reach Level 4~5, dry rubbing fastness is Level 5, and wet rubbing fastness is Level 4~5. The introduction of polymer dyes can improve the mechanical properties of transparent leather. When the amount of polymer dye is 0.14%, the tensile strength and tear strength of transparent leather can be increased by 2.7 times and 2.4 times respectively. At the same time, polymer dyes have little effect on the water vapor permeability of transparent leather.
