阳离子改性剂聚环氧氯丙烷胺化物的应用

Application of Cationic Modifying Agent PECH-Amine to Cellulosic Fibres

纤维素纤维用聚环氧氯丙烷胺化物改性，并用直接染料、反应性染料中性、无盐染色。对改性过程中碱浓度、改性剂浓度、改性处理所需时间对染色的影响以及改性前后纤维素纤维的染色情况作了讨论。

Cellulosic fibres were treated with cationic modifying agents of PECH-amine and dyed with direct and reactive dyes without salts under neutral condi- tions. The pretreatment was found to increase exhaustion efficiently，and no residue dyes left in the dyeing effluent could be brought about. The effect of alkali and cationic agent concentrations，along with modification time on dyeing of treated cotton is also discussed.
