Description
技术领域
本发明涉及纺织助剂技术领域，具体涉及一种棉用挺括型柔软剂及其制备方法。
背景技术
棉纤维是天然纤维，具有良好的吸湿透气性、保温保暖性、耐热性、耐碱性和亲肤柔软性等优点，各类棉纤维的服装一直都倍受消费者的青睐。可是，在穿戴和洗刷过程容易皱、易变形，缺乏弹性，皱了以后比较难抚平，影响了织物的服用性能。尤其是衬衣、连衣裙、外套等服装，起皱变形后没有骨感，失去挺括性，失去干净整洁的外观，成为了一大烦恼。
为了提高它的服用性能，有的从面料的织造开始就添加其他纤维来提高棉纤维的挺括度性。通过增加面料的纤维成份，改善了面料的挺括度，但随之也增加了生产成本。
通过树脂整理、免烫抗皱整理等整理，能使织物获得良好的硬挺度或回弹性。但部分在整理过程中会释放甲醛，对人体和环境造成伤害和污染，失去了棉纤维的天然友好性；部分在整理后手感太硬，失去柔软舒适感；部分在整理后耐水性差，在吸潮或水洗后失去挺括度；部分则是整理剂的离子性太强，不能与其他整理剂有良好的配伍性。
因此，在提高棉纤维织物的挺括性的同时不能失去棉纤维本身的特质，需要开发一种环保、成本低、耐洗水、挺括性好、回弹性好，应用工艺简洁方便，而不失棉纤维本身柔软亲肤的特性的柔软剂。
发明内容
本发明的目的在于克服上述问题而提供一种环保、成本低、耐洗水、挺括性好、回弹性好，应用工艺简洁方便，而不失棉纤维本身柔软亲肤的特性的柔软剂。
为实现上述目的，本发明采取的技术方案是一种棉用挺括型柔软剂，主要包括如下质量百分比的成分，嵌段硅油10～20％、改性聚氨酯乳液5～10％、聚丙烯酸酯2～5％、阳离子表面活性剂10～15％、棕榈酸异丙酯1～4％、聚甘油脂肪酸酯3～6％、烷基多聚糖苷2～4％、交联剂2～5％、防腐剂0.05～0.2％、其余去离子水。
优选地，所述嵌段硅油为硅氧烷、多胺、聚醚的三元共聚物，所述嵌段硅油采用端含氢封头法或端环氧双封头法合成。
优选地，采用端含氢封头法或端环氧双封头法合成的嵌段硅油含量为40～80％。
优选地，所述改性聚氨酯乳液为羟基硅油改性聚氨酯乳液。
优选地，所述聚丙烯酸酯为聚丙烯酸乙酯、丁酯中至少一种。
优选地，所述阳离子表面活性剂为胺盐型、季铵盐型、咪唑啉型中的至少一种。
优选地，所述烷基多聚糖苷为C8-18中至少一种。
优选地，所述防腐剂为羟苯酯类、苯甲酸及其盐类中至少一种。
一种棉用挺括型柔软剂，其特征在于，包括以下步骤：1)制备组分A：将所述嵌段硅油、棕榈酸异丙酯加入均质乳化机中，低速搅拌均匀后，边搅拌边慢慢加入组分中1/3的去离子水，乳化成微乳液后，再加入阳离子表面活性剂和组分中1/3的去离子水，开动均质乳化机，乳化成乳液，出机，待用。
2)制备组分B：将所述改性聚氨酯乳液、聚丙烯酸酯、聚甘油脂肪酸酯、烷基多聚糖苷和组分中1/3的去离子水均质乳化，备用。
3)将组分A、交联剂加入组分B中，均质乳化后，再加入防腐剂，均质乳化成稳定的成品。
本发明的有益效果：本发明的嵌段硅油其能赋予织物滑糯、蓬松的手感，用端环氧双封头法合成的嵌段硅油，稳定性好，手感和亲水性易调整；改性聚氨酯乳液采用羟基硅油改性聚氨酯的乳液，具有良好的乳液稳定性和较小的粒径，胶膜能保持聚氨酯原有的拉伸强度，与纤维结合具有较好的柔软挺度、耐水性和滑爽的手感。聚丙烯酸酯能提升挺括度且不降低柔软度；阳离子表面活性剂能够赋予织物柔软、丰满的舒适感；棕榈酸异丙酯具有优良的渗透性、分散性，既可提高织物的吸湿透气性，又可将各个组分稳定融合；聚甘油脂肪酸酯：是一种新型的高效非离子表面活性剂；烷基多聚糖苷作为非离子表面活性剂，良好的乳化、渗透作用；交联剂主要是促进提升挺括度；防腐剂作为稳定体系的作用。
通过将具有柔软成分的改性有机硅类、非硅类与具有挺括、透气组分的改性高分子化合物的合理复配，制成适用于棉织物的挺括性优异的柔软剂，赋予织物整洁挺括、柔软亲肤、滑糯丰满的手感，且具有优良的耐水洗性及弹性，同时适用于浸轧工艺的后整理工艺。
本发明通过改性有机硅类与非硅类的合理复配，制成一种挺括型的柔软剂。采用端环氧双封头法合成的嵌段硅油与羟基改性的聚氨酯乳液，能与纤维中的羟基大分子结合，渗透进入纤维内部，减少停留在纤维表面成膜，使织物具有类似纸质的挺度又有滑糯、蓬松的手感，赋予织物整洁挺括的外观，良好的耐水洗性及弹性。
本发明不需要从面料织造开始就通过各种方法来提高挺括度，从增加后续处理的工序以及成本。而是作为一种柔软剂，在织物的各个需求的工艺流程完成后，在最后一道工艺过柔软的时候使用，既增加了织物的挺括度，又赋予织物优异的滑糯、丰满感，经水洗多次后仍然可以整洁挺括如新。挺括性与柔软丰满的手感相互增效，并无冲突效果。在过柔软的工艺完成，成本低，工艺简洁。
具体实施方式

应用实施例
对上述实施例1～4的柔软剂在棉织物进行应用性能测试，以棉平布(规格为T/C
即时测试：做完整理后1小时内检测。
湿平衡测试：在标准(恒温恒湿)条件下相对湿度45％，温度20～25℃条件下评测。
整理液配制方法为：柔软剂对涤棉平布重量比是1～3％；柔软剂先用蒸馏水和乙酸配制成重量浓度为10％水乳液(pH≈5)，再按20-30克/升比例再次稀释后配制成整理液。
浸轧工艺：配制整理液→二浸二轧(轧余率70～80％)→烘干(105～110℃×10min)→定型(180℃×60s)→待测。
测试内容如下：
柔软性，专业人士分组触摸评分。
挺括性：专业人士分组触摸评分。
耐洗性，参照GB/T3921-2008标准。
吸水性，沉降法：参照GB/T22864-2009标准。
耐黄变，参照ISO105-X18：2007标准。
测试结果见表1
本发明的柔软剂在染后浸轧法整理织物后，柔软性、挺括性、吸水性明显提高；与市售的平滑硅油柔软剂相比，柔软性稍好，而挺括性、耐洗性、吸水性、耐黄变等应用性能均明显优于市售产品。说明本发明的柔软剂不仅具有柔软剂原本的优异性能，同时挺括性能佳，挺括性与柔软丰满的手感相互增效，并无冲突效果。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明保护的范围之内。
