Description

一种含抗紫外超细羽绒纤维-海藻酸钙微球的水性聚氨酯涂层剂
技术领域
本发明涉及纺织品涂层整理剂技术领域，尤其涉及一种含抗紫外超细羽绒纤维-海藻酸钙微球的水性聚氨酯涂层剂。
背景技术
纺织品涂层整理剂简称涂层剂，是一种涂布于织物表面的高分子化合物薄膜，用以改善织物的风格、手感以及外观等等，极大的提高了纺织品的附加价值。水性聚氨酯涂层剂是一类重要的环保涂层剂，其具有弹性优，手感柔软，耐磨耐溶剂等优点，然而其透湿性较差，严重影响织物的穿着体验，且生产成本高，随着市场需求的提升，研究防水透气类环保聚氨酯织物涂层剂显得尤为重要。《丝素/聚氨酯防水透湿涂层剂的制备及其应用》一文利用丝素对聚氨酯进行改性处理，有效的提高了涂层剂的透湿效果，然而丝素的疏水性较差，随着丝素质量分数的提高涂层膜的耐水性会变差，且丝素的生产成本较高，不利于大规模生产。
我国是羽绒生产大国，年产量遥遥领先于其他国家，羽绒是一种多基团的氨基酸肽链结构的天然蛋白质材料，粗蛋白含量占整个羽绒的80%以上，其结构蓬松柔软，保暖性卓越，具备良好的吸湿性和生物相容性，然而在其资源利用方面的研究利用依旧处于原材料粗加工的水平，除了少量的作为保暖填充材料用于服装和床上用品以外，还有一部分用于体育用品、工艺品以及复合材料的增强材料，大部分都被作为废弃物处理，造成了大量的资源浪费。羽绒在透湿透气性以及耐水性方面均优于丝素，如果能将羽绒有效的引入聚氨酯涂层剂中，将会获得具备优良综合性能的涂层剂，提高织物的经济价值。
