蜂窝光触媒纤维/棉混纺纱纺纱工艺及其性能

为了设计高质量的蜂窝光触媒纤维/棉混纺纱线，本文通过提高环境湿度，利用抗静电剂对蜂窝光触媒纤维进行预处理，纺出6组不同混纺比的蜂窝光触媒纤维/棉混纺纱线，在此基础上测试各组纱线断裂强度、断裂伸长率、毛羽指数和条干均匀度等指标并分析不同混纺比对成纱质量的影响，以探究最优混纺比。研究结果表明：当蜂窝光触媒纤维比例增加至35%之前，纱线的断裂强力和断裂伸长率将随之增加，当蜂窝光触媒纤维比例大于35%时，断裂强力下降，断裂伸长率依然呈递增趋势；条干均匀度和毛羽指数均呈先下降后增加的趋势。

Spinning process of cellular photocatalyst fiber/cotton blended yarns and properties thereof

In order to design photocatalyst fiber/cotton blended yarn in high quality, six blended yarns were produced by raising the humidity and pre-treating fibers with antistatic agent. On this basis, mechanical properties and exterior qualities were tested, and different blended ratios’ effects on yarns’ qualities were given to investigate the best blended ratio. With photocatalyst fiber content increasing, the results shows that blended yarn’s breaking strength and breaking elongation will be enhanced. Especially, once the content of photocatalyst fiber is over the critical ratio of 35%, breaking strength will be deducted while yarn elongation continues increasing and a tendency is found that yarn evenness and hairiness index alike will be decreased at first but increased gradually.
