季铵盐壳聚糖/水性聚氨酯共混膜的制备及防水透湿性能

摘要

将季铵盐壳聚糖( HACC)与水性聚氨酯(WPU)进行共混,对共混膜进行了耐静水压、透湿量性能测试.讨论了HACC用量、共混时间、烘干温度对共混膜防水透湿性能的影响.结果表明,当HACC用量10％～15％,共混时间15～20min,烘干温度100～110℃时,制备的共混膜具有良好的防水透湿性能及共混性能.%In order to further enrich cashmere product category and utilize cashmere resource more rationally, a type of light and thin worsted blending fabric is successfully developed. It was used wool, mulberry silk fiber and cashmere fiber as raw materials, and mainly to the technological process and key techniques through the re-combing, spinning, weaving and finishing four parts to feasible treatment technology. This topic of research and development the superb properties of wool, mulberry silk fiber and cashmere fibers contribute to the superior quality of high count yarn, best quality and superior product performance reduce the consumption of raw material, improves the grade of the product.
