Description
技术领域
本发明属于纺织面料领域，具体涉及一种防水全遮光涤纶面料及其制备方法。
背景技术
涤纶是现阶段应用最多的合成化学纤维之一，其几何规整性较高，分子间作用力强，反应性较弱，故其具有优良的物理化学性能。对涤纶织物进行功能性整理，例如防水、阻燃、抗静电、抗菌、抗皱，高耐水压等，可提高产品档次和附加值。其中，涤纶织物防水全遮光整理是研究的热点之一，其产品广泛应用于产业用纺织品、户外用品以及帐篷等。
目前的整理方法主要有以下方法：
1)干涂层法，其中应用较多的是PU聚氨酯加一些黑色颜料，该黑色颜料和聚氨酯PU相容性差，饱和度和分散度不好，产品加工难度大，成本高，次品率多，布面均匀度差，耐水压低，遮光效率差。
2)泡沫涂层法，整理后的织物克重偏高，厚重，附着布面牢度差，容易老化，耐水压低，设备要求高，不适宜应用于户外用品，帐篷。以上方法还需使用有机溶剂，环境能耗大，难以是实现广泛应用。
3)水性涂层法，此加工的产品牢度差，防水耐水压低，遮光差，难以应用于遮光需求的帐篷面料。
鉴于上述缺点，因此，有必要研发一种超级防水且全遮光涤纶面料的制备方法。
