细纱后区附双根压力棒上销应用分析

探讨细纱后区附双根压力棒新型上销对成纱质量的影响情况.测试分析了细纱后区附双根压力棒新型上销牵伸装置与普通上销纺纱质量的差异,对细纱后区中心距、粗纱捻度、后区牵伸倍数三个工艺参数进行了正交优选试验.结果表明:后区附双根压力棒新型上销牵伸装置对后牵伸区须条的控制增强,可以提高细纱机的后区牵伸能力,增大总牵伸倍数,有利于细号纱纺纱质量的提高.

Application of Double Press Bar Top Pin in Back Zone of Spinning

To discuss the influence of double press bar top pin on yam quality, the yam quality difference between using double press bar top pin draft set and normal top pin was tested, orthogonal test of three processing parameters of center-to-center distance in spinning back zone, roving twist, back zone draft multiple were done. The test shows that double press bar top pin in back zone draft set has bigger control of slivers in back zone, and can enhance back zone draft ability of spinning frame, increase draft multiple, and enhance fine count yam quality.
