并粗工序工艺优选试验

Technology Optimizing Test of Drawing and Roving Process

在FA311A型并条机、TJFA458A型粗纱机上进行了牵伸工艺配置对成纱质量影响的试验。并条质量与成纱质量呈正相关关系,粗纱的主要作用除牵伸、加捻外,还有改善须条内部纤维伸直度及纱条结构的作用。提高半制品条干均匀度和纤维伸直度,对改善成纱质量效果显著。

Test of influence of drafting technology circulation on yarn quality was done in FA311 drawing frame and TJFA458 roving frame. The relation between drawing quality and yarn quality is positive correlation, Except main function of drafting and twist, roving process has the function of improving fiber straightness and yarn structure. The enhancing of semi-finished goods evenness and fiber straightness has significant effect to improve yarn quality.
