苎麻纯落麻转杯纺分梳元件的研究 第三报 粗号纯落麻纱的实用性分析及其产品开发

苎麻纯落麻转杯纺的系列研究已经得出目前纺制纯落麻转杯纱的最优工艺组合。鉴于目前尚未制订出此类纱线的质量标准,本文借助假想的“纯落麻环锭纱”概念,从成纱质量角度分析,得出最优工艺组合下纺制的粗号纯落麻转杯纱具有一定的实用性;在此基础上,利用所纺制的纯落麻转杯纱,成功地开发试织出5种纯落麻机织物及3种落麻针织物面料。

转杯纺复合纱的结构与性能

在经过改装的转杯纺纱机上，通过调整涤纶长丝的超喂率生产不同结构和性能的转杯纺复合纱。长丝超喂率对复合纱的外观、结构和性能均有较显著的影响。当长丝张力随长丝超喂率减小而增加时，长丝从复合纱表面逐渐趋向于分布在纱线内层。复合纱的拉伸性质、条干、毛羽等性能与长丝超喂率有密切联系。与纯棉转杯纱相比，复合纱的外观和性能均有较大程度的改善。     

SOME END-USES OF PURE RAMIE NOIL ROTOR YARNS

In the previous studies, the optimum technological combination has been obtained for producing coarse pure ramie noil yarns on rotor spinning system currently. Because of no yarn properties standard available at present for suchlike yarns, it is considered necessary to analyse the acceptability of coarse pure ramie noil rotor-spun yarns in terms of yarn properties before their products being developed. By the aid of a hypothetical concept "pure ramie noil ring-spun yarn", this paper draws the conclusion that the coarse pure ramie noil rotor-spun yarns are condsidered acceptable to a great extent; furthermore, it introduces 5 kinds of woven fabrics and 3 kinds of knitted fabrics successfully designed and developed from those yarns.
