Modal纤维紧密纺纱的开发

探讨紧密纺技术在Modal纤维纺纱过程中的应用,通过优化试验确定纺纱过程中梳理、并条、粗纱、细纱及络筒的工艺参数。在对成纱原理分析的基础上,优选出紧密纺中最优的集聚张力和负压值,并确定出钢领、钢丝圈及网格圈。通过与紧密纺和普通纺成纱质量进行对比发现,采用紧密纺技术生产的纱线质量较好,毛羽少,条干不匀率仅为10.75%,且断裂强度达到20.73 cN/tex,此外纱线的断头率、纱疵率均降低,生产效率相对提高,体现出紧密纺纱的优越性。

Development of the Modal fiber yarn by compact spinning

The application of compact spinning technology to Modal fibers has been discussed.The parameters in carding,drawing,roving,spinning and winding processes are optimized.And on the basis of the theory of spinning,the assembled tension and the value of the press can be optimized,and proper rings,ring travelers and net loops are determined.After making comparison with compact spinning and common spinning,we find that compact spun yarn has the besty quality,less hairiness,better unevenness(only 10.75%) and tensile strength(20.73 cN/dtex).In addition,the compact spinning is characterized by low end-breakage rate and yarn defects,high production efficiency.
