酯类化合物的释酸效果及对弱酸性染料染色的影响

Acid releasing effect of ester compounds and its influence to dyeing with weakly acid dyes

分析了酯类化合物的释酸机理,对几种酯类化合物的释酸情况及酸性染料染色的影响进行了探讨.实验结果表明,自制的马来酸二酯可随着染色温度的升高,逐步释酸,用于弱酸性染料染色,能减缓染色初期的上染速率,提高匀染性.

The mechanism of acid release of ester compounds was analyzed, and the acid release behaviors of some ester compounds and the influence to dyeing with weakly acid dyes were investigated. The experiments showed that the maleic diesters made by the author could gradually release acid as increasing the dyeing temperature and could retard the initial dye pickup in dyeing to enhance leveling when they were used in dyeing with weakly acid dyes.
