混纺比对竹浆棉混纺纱条干和毛羽的影响

为探讨竹浆纤维棉纤维混纺纱中竹浆纤维含量的变化对纱线条干和毛羽的影响规律,测试分析了不同混纺比例的竹浆纤维棉纤维混纺纱线的条干和毛羽性能.测试结果表明:当混纺纱中竹浆纤维与棉纤维混纺比为30/70时,混纺纱的条干明显恶化,在实际生产中,应避免选用这一临界混纺比;竹浆纤维与棉纤维混纺比在55/45～70/30之间时对纱线条干较有利;竹浆纤维与棉纤维混纺比例为55/45时,混纺纱的毛羽指数较低;综合考虑,竹浆纤维棉纤维混纺纱在混纺比为55/45时成纱性能较佳.

Effect of Blending Ratio on Bamboo Cotton Blended Yarn Evenness and Hairiness

Influential law of bamboo fibre content change on yarn evenness and hairiness in bamboo cotton blended yarn were discussed. Evenness and hairiness of bamboo cotton blended yarn with different blending ratio were tested and analysed. The result shows that blended yarn evenness is becoming worse obviously when blending ratio of bamboo and cotton is 30/70, which should be avoided in practical production. Yarn evenness is better when bamboo cotton blending ratio is between 55/45 to 70/30. Blended yarn hairiness index is lower when bamboo cotton blending ratio is 55/45. Based on an overall consideration, blended yarn property is best when bamboo cotton blending ratio is 55/45.
