Description

一种高效环保染色促进剂及其制备方法
技术领域:
本发明涉及纺织助剂技术领域,具体的涉及一种高效环保染色促进剂。
背景技术:
近年来,随着人们环境保护意识不断加强,天然纤维纺织品日益受到消费者的青睐。蚕丝纤维有“纤维皇后”之美称,具有无与伦比的独特性能:轻薄滑爽,柔软舒适,良好的吸湿、透气性、特有的柔和亮丽光泽,而且对人体具有保健作用;因此真丝产品备受人们喜爱。棉纤维作为天然纤维素纤维,具有良好的吸湿性、染色性以及一定的耐磨性,透气性好,用其制成服装穿着舒适,不易起球。此外,麻纤维等天然纤维制品业以其优良的吸湿、保健性能而受到关注。
聚乳酸纤维是一种新型的可完全生物降解的合成纤维,它具有一般合成纤维的综合优良性能,尤其是生物可降解性,是其他聚酯纤维所无法比拟的,因此,它为纺织品领域带来了新的发展空间,但同时也为染整加工带来了新的挑战。聚乳酸主要用分散染料染色,但是与聚酯纤维相比,常用的商品分散染料在聚乳酸纤维上的上染率远低于PET纤维,其染深性较差,且由于聚乳酸本身没有吸收紫外线的基团,分散染料染色后织物经光照易褪色,因此耐光色牢度的提高也是一个亟待解决的问题。
中国专利(CN201310276149.8)公开了一种染色促进剂的制备方法,其首先利用四氯化碳、三氟化硼乙醚、乙二醇、环氧氯丙烷反应,然后采用丙酮-乙醇混合液提纯,再加入乙二胺四乙酸四钠水溶液除去提取物中的低分子齐聚物,得到端羟基聚环氧氯丙烷;然后端羟基聚环氧氯丙烷以及二甲胺水溶液分置两个容器,向置于聚环氧氯丙烷的容器中滴加二甲胺水溶液,一定条件下反应,即得到染色促进剂DL-71。该方法制备得到的可以有效提高天然蚕丝纤维的上染率,但是其制备工艺复杂,制备过程中采用的溶剂易挥发,不利于环境保护。
发明内容:
本发明的目的是提供一种高效环保染色促进剂,其可以有效提高织物的上染率,染色后的织物湿牢度和耐光牢度都大大提高,且染色效果优异。且该染色促进剂具有一定的生物降解性,无毒,有利于环境保护。
