摘要：低温皂洗是活性染料染色过程实现节能降耗的重要环节,探讨了皂洗剂类型、
皂洗温度、皂洗时间、助剂用量、工作液pH 等对皂洗效果的影响,在低温皂洗剂DM-1542用量为2~3g/L,皂洗温度60℃,皂洗时间30min,pH=10的工艺条件下,染色后的皂洗牢度可达到常规高温工艺的水平,且皂洗后织物得色量略高于常规工艺.

Abstract:Low temperature soaping in reactive dyeing is one of the most important processes to save en ?ergy and reduce consumption.The effects of kinds of soaping agents,soaping time,assistant dosage and pH on the soaping result were studied.It was found that under the process that the DM-1542dosage was 2~3g/L,the soaping temperature was 60℃,the soaping time was 30min and pH=10,the soaping fastness of the dyed fabric could reach the level of conventional high temperature soaping process for most reactive dyes.And the color yield of the soaped fabric was slightly higher than that of the conventional process.
Key words:reactive dyes;low temperature soaping agent;soaping fastness;energy conservation and consumption reduction

作者简介：姜佳丽(1977-),女,黑龙江齐齐哈尔人,讲师,博士,主要研究精细化学品的合成与应用.活性染料色谱齐全,价格低廉,色牢度好,是纤维
素纤维染色使用最多的染料,但染色结束后大量的水
解染料仍附着在纤维表面,形成浮色,需要通过后处
理来去除,以提高各项牢度.传统的染色后处理需要
进行多次水洗,一般皂洗温度在90~100℃,有些厂家
甚至在110℃皂洗,从而造成整个皂洗工艺耗时长,水
耗、能耗高,织物表面染料剥除多,色变大[1-4].寻求更高
效、更节能的皂洗工艺是当前研究的主要方向.高温皂洗有利于纤维内部的水解染料向纤维表
面扩散,也有利于提高皂洗剂的渗透性和溶解度,从而达到较好的皂洗效果.因此,对于低温皂洗,若想确保良好的皂洗和防沾色效果,需要皂洗剂在低温条件下具有极佳的溶解性和良好的分散性.目前,常见的市售低温皂洗剂有表面活性剂型、氧化还原型、生物酶复配型等.[5-6]本文对几种低温皂洗剂以及由多孔性结构物质复配而成的低温皂洗剂DM-1542进行了应用研究,试验表明,低温皂洗剂DM-1542可广泛用于活性染料染色、印花后的皂洗,在60~80℃时具有良好的去除浮色和防沾色作用,可有效提高产品色牢度.活性染料低温皂洗剂的应用研究
