高支色纺纱织造难点分析及工艺改进

Difficulties Analysis and Process Improvement of High-count Colored Spun Yarn

文章通过对9.7 tex高支色纺纱纱线指标及织造难点的分析,指出了高支色纺纱织造难度大主要是因为纱线强力、毛羽、耐磨性等指标差,造成织机经纬停高、织造效率低;并根据高支色纺纱的特点,通过对浆纱压力、浆槽浓度及温度等工艺改进和浆料配方的优化,提升了浆纱指标和织轴质量,同时通过对经轴水洗、纬纱加湿以及织造工艺参数的调整,减少了经纱浆锅断头及织机纬停高的问题,降低了织机经纬停次数,解决了高支色纺纱在织造过程中经纬停高、织造效率低的问题。

Based on the analysis of yarn index and weaving difficulties of 9.7 tex high-count colored spun yarn,the paper pointed out that its difficulties were mainly due to poor yarn strength,hairiness and abrasion resistance,which caused several times of machine stoppage,as well as low weaving efficiency.Based on the characteristics of high-count colored spun yarn,the sizing index and the yarn quality of the loom beam are improved by the process improvement,including,the sizing pressure,the concentration of the sizing and the temperature,as well as the optimization of the sizing formula.By adjusting the parameters of washing of warp beam,humidification of weft yarn and weaving process,the problem of warp yarn breakage and frequent machine stoppage due to weft problems are solved,thus,improving weaving efficiency.
