| 摘 要： | 细纱牵伸过程中,为避免捻回重分布导致成纱条干恶化,粗纱捻系数与细纱后区牵伸必须进行合理搭配.采用模糊决策方法中的Borda数法,对纯棉普梳纱线的粗纱捻系数和细纱后区牵伸倍数的搭配方案进行排序,从而获得成纱质量较优的两个工艺参数的配合方案,并对该方案进行了上机验证.试验结果表明,采用模糊决策方法优选方案进行纺纱,所得纱线质量较好;较大的粗纱捻系数和较小的细纱后区牵伸配合能够获得较优质量的纱线.

| Abstract: | In ring spinning process,roving twist factor and break draft ratio in ring frame should be reasonably designed in order to avoid the twist redistribution on drafted strand.The arrangement of these parameters is sort in order by using Borda number law in fuzzy decision making method(FDM)to get optimal project for better quality yarn,and optimal parameters are verified in the ring spinning.The results show that: optimal parameters gained by Borda number law in FDM can be used to get better quality yarns;a lar... |
