粗纱包芯纱棉涤针织纱的研究与开发

Study and Development of Cotton Polyester Roving Cor e Spun Yar n

采用染色棉纤维和涤纶纤维进行包芯纱纺纱,通过粗纱设备改造开发短纤包短纤的粗纱包芯纱棉涤针织纱线。介绍了两种开发方案,即棉条包涤纶条和棉条包涤纶粗纱条纺纱工艺,包括工艺流程、粗纱机改造,并介绍了粗纱、细纱、络筒3个关键的纺纱工序,总结了粗纱包芯纱工艺的操作方法、注意事项及创新点。结果表明,粗纱包芯纱棉涤针织纱的纺纱工序可操作性好,其面料手感蓬松、穿着舒适。

The dyed cotton fiber and polyester fiber were used to spin core spun yarn. Cottton polyester roving core spun yarn with staple fiber covering staple fiber for knitting were developed through roving frame reformation. Based on technologieal process and roving frame modification, two developed methods that cotton sliver clads polyester sliver and cotton sliver covers polyester coarse sliver spinning process were introduced. Three key spinning processes including roving, spinning and winding processes were introduced, and the operation methods, matters needing attentions and innovation points of the roving core yarn process were sunnnarized. The resuhs show that the spinning process of cotton polyster roving core spun yarn for knitting is feasible and the fabric feels fluffy and comfortable.
