胶辊硬度与紫外线光照对细特涤纶混纺纱质量的影响

The Influence of Cot Hardness and Ultraviolet Light on the Quality of Fine Polyester Blended Yarn

为了提高细特涤纶混纺纱质量,介绍涤纶混纺细号纱用胶辊的要求、选型原则,用不同硬度、不同紫外线光照时间的细纱胶辊试纺细特T/R 60/4011.8 tex纱,分析其对纱线质量的影响。结果表明:选择胶辊应以纱线号数、纤维性能和成纱质量稳定性为依据,兼顾胶辊硬度及其表面处理因素;纺制涤纶混纺纱线的成纱质量与胶辊硬度及表面紫外线光照处理时长有显著性关系;光照时间为120 s、邵尔A硬度为66度的胶辊综合成纱质量最优。

In order to improve the quality of fine polyester blended yarn,the requirements and the selection principle of cots for fine polyester blended yarn are introduced,the test spinning fine T/R 60/4011.8 tex yarn with spinning cots of different hardness and ultraviolet light duration,and the influence on the yarn quality is analyzed.The results show that the selection of cots should be based on the yarn count,fiber properties and yarn quality stability,as well as the factors of cot hardness and surface treatment.The spinning quality of polyester blended yarn is significantly related to the hardness of cots and the treatment duration of ultraviolet light,the comprehensive yarn quality of cots with light time of 120 seconds and shore hardness A of 66 degrees is the best.
