Abstract

本发明公开了一种防水透气面料及其制备方法，为实现面料的防水透气透湿性能优异，本申请以聚四氟乙烯膜为里层膜，棉面料为中间面料，表面疏水处理后的涤纶面料为外面料，三者依次堆叠，并通过聚酰胺热熔胶热压复合，以得到复合面料；中间层引入棉面料，其中棉面料表面引入氨基，能够大大提高棉面料的亲水性能，由于棉面料与聚四氟乙烯膜之间亲水、疏水差异，当面料里侧与外侧存在湿度差时，棉面料具有优异的亲水导湿性，能够为湿气透过面料提供动力，以进一步提高面料的透湿性能。本发明制备得到的面料不仅具有优异的防水透湿性能，而且具有优异的抗菌性能，能够有效避免细菌滋生，且面料耐水洗，具有较高的实用性。

Description

一种防水透气面料及其制备方法
技术领域
本发明涉及面料技术领域，具体为一种防水透气面料及其制备方法。
背景技术
防水透气面料是一种新型的纺织面料，其成份由的高分子防水透气材料（PTFE膜）与布料复合而成。根据不同产品需求作两层复合及三层复合，它被广泛应用于户外服饰、登山服、风衣、雨衣、鞋帽手套、防寒夹克、体育用品、医疗设备等，且被逐步应用于时尚服饰。
现有的防水透气面料的防水透湿性能较差，在使用时无法及时排除汗液，同时由于汗液排除不及时，面料在潮湿环境下容易滋生细菌，实际使用感官较差，无法满足我们的实际需求。
因此，针对上述情况，我们公开了一种防水透气面料及其制备方法，以解决该技术问题。
发明内容
本发明的目的在于提供一种防水透气面料及其制备方法，以解决上述背景技术中提出的问题。

与现有技术相比，本发明所达到的有益效果是：
本发明公开了一种防水透气面料及其制备方法，为实现面料的防水透气透湿性能优异，本申请以聚四氟乙烯膜为里层膜，表面负载抗菌成分的棉面料为中间面料，表面疏水处理后的涤纶面料为外面料，三者依次堆叠，并通过聚酰胺热熔胶热压复合，以得到复合面料；
聚四氟乙烯膜是一种柔韧而富有弹性的微孔材料，具有透气但不透水的特性，以其为里层膜，可以有效实现防水透湿效果；在中间层引入棉面料，其中棉面料表面通过3-氨丙基三乙氧基硅烷接枝以引入氨基，能够大大提高棉面料的亲水性能，由于棉面料与聚四氟乙烯膜之间亲水、疏水差异，当面料里侧与外侧存在湿度差时，棉面料具有优异的亲水导湿性，能够为湿气透过面料提供动力，以进一步提高面料的透湿性能。
同时，由于湿气会经过中间棉面料导湿，并由外侧的疏水涤纶面料排出，在该过程中面料会因为透湿作用而滋生细菌，不可避免的，对于面料的抗菌性能也需要进行功能限定；因此本申请引入了二氧化钛和聚六亚甲基胍盐酸盐，加工时先对二氧化钛表面进行环氧基接枝，其表面的环氧基会与聚六亚甲基胍盐酸盐上的氨基接枝反应，由于聚六亚甲基胍盐酸盐具有优异的抗菌性能，能够有效提高面料的抗菌性能，避免细菌滋生。
在该过程中，本申请限定了预处理二氧化钛与聚六亚甲基胍盐酸盐的摩尔比为9：4，该参数条件下，二氧化钛表面的环氧基远大于聚六亚甲基胍盐酸盐的氨基含量，剩余的环氧基能够与面料表面引入的氨基交联接枝，因此接枝有聚六亚甲基胍盐酸盐的二氧化钛能够有效负载在面料表面，且不易脱落，面料水洗后依旧能保持优异的抗菌性能；而当预处理二氧化钛与聚六亚甲基胍盐酸盐的摩尔比小于9：4时，会出现二氧化钛负载量低，负载效果差，且易脱落的情况，从而影响面料的抗菌性能。
同时，在现有常规技术操作中，面料表面引入氨基一般会采用氨基硅油对其进行表面处理，但本申请并未选择该方案，而是通过3-氨丙基三乙氧基硅烷接枝引入氨基，这是因为，本申请不仅需要引入氨基，以保证后续负载具有抗菌性能的二氧化钛，另一方面，为保证面料的防水透湿性能，本申请依旧需要保持面料的亲水性能，3-氨丙基三乙氧基硅烷是小分子物质，与棉面料共价结合后能够获得比羟基亲水性更好的氨基，亲水性能大大增加，能够有效保证本方案的实施。
在此基础上，本申请将氟硅烷喷涂至涤纶面料表面，该步骤可大大提高面料表面疏水性能，提高表面的水接触角，以进一步提高面料的防水性能。
本发明公开了一种防水透气面料及其制备方法，工艺设计合理，操作简单，制备得到的面料不仅具有优异的防水透湿性能，而且具有优异的抗菌、透气性，能够有效避免细菌滋生，且面料耐水洗，具有较高的实用性。
