摘　　要：在生产CJ11.7tex纱的基础上分析了纱线条干均匀度的影响因素。为了提高细纱条干均匀度,对影响成纱条干均匀度的前区工艺参数、后区牵伸工艺进行了工艺配置。实验结果证明,采用较小的粗纱定量、细纱捻系数、前中罗拉隔距、较小的钳口隔距、较小的后区牵伸倍数,以及较大的前胶辊压力,采用较大前胶辊直径,适当增加粗纱捻系数等措施,可以提高成纱条干CV值。The influence factors of yarn evenness were analyzed on the basis of CJll. 7 tex yarn production. In order to improving the yarn evenness, the front zone roller process parameters and back roller draft process were configured. The test results indicated that smaller weight of roving, front zone roller gauge, smaller nip gauge, smaller back roller draft up, bigger front top roller pres- sure, bigger top roller diameter and bigger roving twist factor and so on were selected to improve the CV value of spinning yarn.
