一种防水透气弹力面料及其制备方法
技术领域
本发明涉及面料技术领域，具体涉及一种防水透气弹力面料及其制备方法。
背景技术
随着现代纺织业的不断发展和人民生活水平的提高，消费者对面料的功能化要求越来越高，在满足舒适性能的基础上，越来越多风格迥异，功能丰富的面料开始出现。人们对面料的功能性、舒适性、安全性、保健性和环保性等都有更高的要求，尤其是在户外运动中，对服装面料的防水、防风、透气、保暖甚至抗菌性能有更高的要求。
在功能性纺织面料中，防水透气弹性面料是纺织产品研究开发的热点，中国专利CN109177370A公开了一种三层复合防水透气面料，包括面料内层、面料夹层和防水层；面料内层和面料夹层的表面均粘结有橡胶柱；防水层为防水透气薄膜；制备的面料具有良好的透气性和防风防水保暖性，上述专利存在的不足是面料内层与面料夹层间通过胶黏剂粘合，橡胶柱间等间距粘结子在面料内层和面料夹层表面，防水透气薄膜是通过聚氨酯热熔胶热压复合与面料夹层表面，多种结构间采用环氧树脂胶黏剂、聚氨酯热熔胶，会使得纺织面料的舒适度降低，面料防水防风性能持久性不佳，面料使用寿命缩短，以及该三层防水透气面料的弹性较差，也不具有抗菌性。
中国专利CN103587193A公开了一种防风防水透气面料，面料依次包括外层、面料层和里层，所述外层、面料层和里层压合在一起，其中外层为防风防水透气膜，面料层为织物，里层为四管道纤维材料层。其中所述防风防水透气膜为微孔聚氨酯膜；所述外层外还设置有保护层，所述保护层为聚偏氟乙烯喷涂膜。该纺织面料虽然防水透气性能优异，但面料采用的材料弹性和力学性能上稍显不足。
