粗纱工艺参数的优化配置研究

Study on the optimal allocation of the roving process parameters

对粗纱工序影响成纱质量的工艺参数进行了全方位的分析,发现影响粗纱成纱质量的工艺参数主要有锭翼速度、前区隔距、主牵伸区隔距、后区隔距、后区牵伸倍数、上下销钳口隔距和捻系数等.针对这些工艺参数在粗纱机上进行正交试验,纺制普梳纯棉18.2 tex纱线,对产生的数据进行极差和方差分析,优选出能够获得最佳粗纱成纱质量的工艺参数.对得到的工艺参数上机试验并纺制成细纱测试其质量,其成纱质量数值在乌斯特2007年公报5%水平以内,说明优选的工艺参数可以应用于生产实践,对生产企业探索其他品种的工艺参数配置具有理论和实践指导意义.

In this paper,the impact of roving processing parameters on yarn quality parameters is completely analyzed and it is found that the main factors are flyer speed,front zone gauge,the main drafting zone gauge,back zone gauge,the break draft ratio,jaws gauge between the upper and lower pins,twist factor,etc. Cotton 18. 2 tex yarn is spun and eighteen orthogonal experiments are performed on roving machine. The resulting data are analyzed by range and variance and the optimal process parameters are obtained.After practicing optimal roving processing parameters,yarn quality value is within Uster 2007 Statistics 5% level. It is indicated that the preferred configuration of the process parameters can be applied to production practice. This study provided theoretical and practical reference for other enterprises.
