环锭纺竹浆/棉混纺纱线的性能研究

Study on Property of Ring Spinning Regenerated Bamboo/Cotton Blended Yarns

为了探究竹浆/棉混纺纱线的最优混纺比,通过改变竹浆纤维含量,制备了具有相同线密度和捻度的竹浆/棉混纺纱线,测试了竹浆/棉混纺纱线的条干均匀度、表观形态结构及力学性能,并讨论了竹浆纤维含量对竹浆/棉混纺纱线条干均匀性和力学性能的影响。试验结果表明:当竹浆纤维含量分别为10%,20%和40%时,纱线的条干均匀度优于纯棉纱线,且竹浆纤维比例的增加有利于改善纱线的条干均匀度;当竹浆纤维含量低于10%时,纱线的断裂强度基本呈上升趋势,随着竹浆纤维含量的进一步提高,纱线的断裂强度呈较明显的下降趋势;从纱线外观质量、力学性能及成本综合评价,应选择竹浆纤维含量在10%。

In order to explore the best ratio of regenerated bamboo/cotton bienctea yarn, tm~ paper prepares yarns with different regenerated bamboo ratios, the same linear density and twist level, and measures yarn evenness, morphology structure and mechnical property. Furthermore, the influence of regenerated bamboo ratio on yarn evenness and mechnical property is also analyzed. The experimental results show that yarn evenness is better than that of cotton yarn when regenerated bamboo ratio is 10% ,20% and 40% and that it can be improved as the ratio of regenerated bamboo increases. While ratio of regenerated bamboo is below 10%, the breaking strength goes up in general. However, it obviously goes down with increasing regenerated bamboo ratio. Judging from yarn appearance quality,mechnical property and cost, ratio of regenerated bamboo fiber 10% can be chosen.
