Abstract

本发明涉及一种纺织浆料，包括以下质量份数的各组分：5‑8份甲苯二异氰酸酯、8‑12份聚丙二元醇、30‑40份淀粉、40‑60份水。该纺织浆料易于退浆，生物降解速度快且没有环境污染。

Description

纺织浆料
技术领域
本发明涉及一种纺织浆料，属于纺织工程技术领域。
背景技术
经纱上浆是织造的关键步骤之一，上浆效果的好坏直接决定了织造效率与织物质量，影响上浆效果的主要因素是浆料的上浆性能。随着人们对节能、环保意识的逐渐增强，对浆料的上浆性能提出了更高的要求。淀粉类纺织浆料是一种再生资源，具有来源广泛、价格低廉及环境友好等特点，是目前广泛使用的浆纱材料。但现有的淀粉类纺织浆料中往往会添加聚乙烯醇，聚乙烯醇纺织浆料具有优异的浆膜性能和良好的粘附性能，但聚乙烯醇属于高难度生物降解的有机物，存在退浆性能差和环境保护的问题。
发明内容
本发明要解决技术问题是：克服上述技术的缺点，提供一种易于退浆，生物降解速度快，没有环境污染的纺织浆料。
为了解决上述技术问题，本发明提出的技术方案是：一种纺织浆料，包括以下质量份数的各组分：5-8份甲苯二异氰酸酯、8-12份聚丙二元醇、30-40份淀粉、40-60份水。
本发明带来的有益效果是：本发明没有使用聚乙烯醇，而是采用甲苯二异氰酸酯是水溶性高分子化合物，它具有良好的水溶性，与亲水性纤维具有很好的粘着性能，而聚丙二元醇可以提高分子链的柔顺性，与淀粉混合后，具有很好的上浆性能，也易于退浆，生物降解速度快，没有环境污染。
上述技术方案的进一步改进是：所述淀粉为醋酸酯淀粉，所述醋酸酯淀粉以天然淀粉为母体，与醋酸乙烯酯通过酯化反应而制得，其中醋酸乙烯酯的加入量为天然淀粉质量的3-15%。醋酸酯淀粉为变性淀粉，通过天然淀粉与醋酸乙烯酯的酯化反应，改变天然淀粉的糊化温度以及热粘度，提高纺织浆料的上浆性能。
上述技术方案的进一步改进是：还包括0.8-1.2份丙酮。丙酮可以在保证纺织浆料的上浆性能基础上，最大化的降低纺织浆料的黏度。
具体实施方式
本实施例的纺织浆料，包括以下质量份数的各组分：5-8份甲苯二异氰酸酯、8-12份聚丙二元醇、30-40份淀粉、40-60份水。在制备时，将甲丙二异氰酸酯、聚丙二元醇、淀粉以及水通过搅拌器混合均匀后，加热至70度，反应1-2h，然后降至40度进行搅拌后再蒸馏即得。为了降低纺织浆料的黏度，上述混合物中还包括0.8-1.2份丙酮。
所述淀粉优选醋酸酯淀粉，所述醋酸酯淀粉以天然淀粉为母体，与醋酸乙烯酯通过酯化反应而制得，其中醋酸乙烯酯的加入量为天然淀粉质量的3-15%。醋酸酯淀粉为变性淀粉，通过天然淀粉与醋酸乙烯酯的酯化反应，改变天然淀粉的糊化温度以及热粘度，提高纺织浆料的上浆性能。
本发明不局限于上述实施例所述的具体技术方案，除上述实施例外，本发明还可以有其他实施方式。对于本领域的技术人员来说，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等形成的技术方案，均应包含在本发明的保护范围之内。
