摘要
纺制纯阻燃黏胶纱和混纺比分别为8:2、7:3、6:4、5:5的阻燃黏胶和聚乳酸纤维混纺纱,并将各混纺比纱线合股后,在电脑横机上编织5种纬平针织物,探讨混纺纱及阻燃织物相关性能。结果表明,混纺纱断裂强度和伸长率都随聚乳酸纤维含量的增加而增加,而阻燃黏胶、聚乳酸纤维混纺针织物极限氧指数随阻燃黏胶含量的减少而降低。综合考虑纱线和织物性能,阻燃黏胶、聚乳酸纤维混纺比为6:4时针织物性能较优。
The paper develops 5 kinds of plain knitted fabrics on the computerized flat knitting machine by using flame retardant viscose and polylactic acid fiber blended yarn with different blended ratios（100%,8∶2,7∶3,6∶4,5∶5）. And the relevant properties of blended yarns and flame retardant fabrics are tested and analyzed. The results show that both the breaking strength and elongations of blended yarns increase with the content of polylactic acid fibers;and the critical oxygen indexes of blended knitted fabrics reduce with the content of flame retardant viscose fibers. Considering the performance of the yarns and fabrics in total, the knitted fabric show a better performance under a blended ratio of 6∶4.
