摘要
对粗纱工艺的四个工艺参数:罗拉后区牵伸倍数、罗拉后区隔距、罗拉加压量和粗纱捻度设计四因素四水平正交试验,得出最优工艺参数:罗拉后区牵伸倍数为1.16;罗拉后区隔距为32 mm;罗拉加压量为3.5 Pa;粗纱捻度为1.17 T/in。对优化后的参数进行第二次试验,与原来试验相比,成纱条干改善0.91%。
The experiment of four factors such as roller drafting ratio, roller back gauge, roller pressure and roving twist, and four levels was designed. The optimal process parameters were obtained：roller drafting ratio was 1. 16, roller back gauge was 32 mm, roller pressure was 3. 5 Pa, roving twist was 1. 17 T/in. The second experiment based on the optimal parameters showed that, compared with the original test, the yarn evenness improved 0. 91%.
