采用黄柏、槐米与茜草中提取的植物染料对黏胶织物进行功能整理.测试表明,黄柏、槐米与茜草中提取的植物染料对远紫外线与近紫外线具有较好的吸收性能.染色后织物的抗紫外线性能均有不同程度提高,其折皱回复角、回潮率与断裂强力不同程度下降,变化幅度与植物染料的上染率呈正相关关系.经摩擦后,黏胶织物与染色皂洗织物相比,折皱回复角、回潮率略高,断裂强力略低,对织物的服用性能影响较小.研究认为:黄柏、槐米与茜草染料对黏胶织物进行防紫外线功能整理具有较强的可行性.

为了探究双组分聚烯烃非织造材料在空气过滤领域的应用前景,分别选取针刺、纺黏、热风3种非织造工艺制备了聚乙稀/聚丙烯(PE/PP)双组分空气过滤材料,并对滤材的结构、纤维直径、表面形貌、孔径和过滤性能进行系统表征.为提高滤材的过滤性能,对3种试样均进行了驻极处理.试验结果表明,经驻极处理后,针刺和纺黏非织造滤料的过滤效率均达到高中效过滤器使用标准,热风非织造滤料的过滤效率达到中效过滤器标准.其中,针刺非织造滤料的平均孔径为32.81 μm,驻极后的过滤效率为75.53%,阻力压降为5.91 Pa,品质因数为
