Description

一种环保型防泳移剂及其制备方法
一、技术领域
本发明涉及一种环保型防泳移剂及其制备方法,以克服涤纶及其混纺品在连续轧染过程中染料染色泳移的问题。
二、背景技术
涤纶的染色性能较差,一般须在高温或有载体存在的条件下用分散染料染色。涤纶及其混纺品的热熔染色中,染料泳移问题十分突出,造成染色不匀的难题。我国以前常用天然的高分子物质(如海藻酸钠、果胶等)作防泳移剂,但对染液稳定性有影响,特别是夏天,染液易变质。
因此,开发与染料和助剂相容性好,能提高染浴的稳定性,不与染料发生物理化学反应而影响染料上染的防泳移剂尤为重要。
三、发明内容
本发明针对涤纶及其混纺品的热熔染色中染料泳移问题造成染色不匀的难题,提供一种环保型防泳移剂及其制备方法。本发明防泳移剂具有网络状高分子结构,与涤纶有一定的亲和力吸附性,易于凝胶化吸附,克服涤纶及其混纺织物在长车染色过程中的泳移现象。
本发明防泳移剂防泳移效果好,无毒,无公害,易降解,环保,较现有技术在生产使用中用量减少10%。
本发明防泳移剂,由组分A和组分B构成,组分B的质量占防泳移剂总质量的1-2%。
组分A是甲基丙烯酸、丙烯酰胺和顺丁烯二酸酐按质量比15.0-20.0:10.0-15.0:3.0-5.0的比例加成后得到的产物,反应式如下:
组分B是由CMC和海藻酸钠按质量比2:8混合后得到的混合物。
在纺织品连续轧染中,特别是在涤纶及其混纺织物的热熔染色过程中,染料的泳移问题十分突出。染料的泳移主要是因为织物在烘干时,染料尚未固着在纤维上,仅仅是附着在纤维表面,这时如果织物布面上下、左右水分挥发速度不一(由温度不一造成的),造成织物不同部位含水量的差异,由于织物的毛细效应,水分由含量多的部位向含量少的部位转移,染料同时跟随水分的移动而移动,使织物表面染料浓度出现差异,而产生织物的正反面色差或左右色差。
本发明防泳移剂是一种高分子聚合物(数均分子量为20-40万),由于高分子长链与染料之间产生吸附而形成疏松的凝聚体,如凝聚体的颗粒大小比纤维中的毛细管直径大时,染料就会被毛细管滞留而不会随水分的移动而移动了。防泳移剂高分子与染料的凝聚能力越大,该防泳移剂的防泳移能力越强。
本发明防泳移剂的制备方法,包括如下步骤:
1、在反应釜中,按配比量加入甲基丙烯酸、丙烯酰胺和顺丁烯二酸酐以及去离子水,搅拌溶解,用20%的氢氧化钠溶液调节pH值至6.5-7.5,降至室温后加入引发剂过硫酸钾溶液,获得反应液;取调配好的反应液的2/3,加入到装有温度计的另一只反应釜中,搅拌下加热至85~95℃,保温反应30分钟,随后滴加余下的反应液,约1小时滴加完,同温度下继续保温反应2小时,反应结束后冷却到室温,得到的反应产物即为组分A;
甲基丙烯酸、丙烯酰胺、顺丁烯二酸酐、过硫酸钾溶液以及去离子水的质量比为15.0-20.0:10.0-15.0:3.0-5.0:2.0-5.0:70.0-58.5,其中过硫酸钾溶液的质量浓度为10%。
2、将CMC和海藻酸钠按质量比2:8的比例混合即得组分B;
3、将组份A和组分B按配比量混合,即得环保型防泳移剂。
本发明防泳移剂为无色粘稠液体,pH=6.5-7.5,是一种高分子化合物,使用中高分子长链与染料之间产生吸附而形成疏松的凝聚体,凝聚体的颗粒大于纤维中的毛细管直径,染料就会被毛细管滞留而不会随水分移动,彻底解决连续染色时,染料的泳移问题。
本发明通过对原料的筛选,工艺的优化,提高了产品凝聚性能,使产品在使用中用量较现有产品减少10%,降低企业生产成本。
本发明产品无毒无公害,易生物降解,属环保产品。具有制备过程易于控制、操作简单、产品稳定等特点。
与已有技术相比,本发明具有以下优点:
1、原料来源广泛,制备方便,价格低廉;
2、防泳移性强,防止产生织物表面色差和白芯现象;
3、与染料和助剂相容性好,能提高染浴的稳定性,不与染料发生物理化学反应而影响染料的上染;
4、不沾污轧辊和辊筒,易于清洗;
5、起泡性少,能够改善染料的给色量和固色率;
6、具有独特的凝聚性能,用量较现有产品减少10%;
7、本发明产品无毒无公害,易生物降解,属环保产品。
