棉Formotex木棉混纺纱的生产实践

为顺利纺制棉Formotex木棉混纺纱,针对混纺纤维的性能特点,采用包混工艺,并对木棉纤维进行纺前预处理;开清棉工序重点减少纤维损伤;并条工序合理设置罗拉隔距和后区牵伸倍数;粗纱工序适当增大捻系数,以减少意外牵伸;细纱工序优选钢领、钢丝圈型号,以减少成纱毛羽;络筒工序合理设定清纱器参数,清除有害纱疵,最终成功纺制出棉/Formotex/木棉60/30/10 14.5 tex纱,其质量满足了使用要求。

Production of Cotton Formotex Kapok Blended Yarn

To spin cotton Formotex kapok blended yarn,according to blended fiber properties,processing of fiber multi-bale blending was adopted,kapok fiber was pre-treated.In picking process,fiber injury should be reduced as a key point.In drawing process,roller guages and draft in back zone should be set rationally.In roving process,twist factor was increased properly to reduce accident draft.In spinning process,ring and ring traveler were optimized to reduce yarn hairiness.In winding process,parameter of electronic yarn clearer were selected rationally to reduce harmful defects.Finally cotton/Formotex/kapok 60/30/10 14.5 tex yarn can be spun successfully,the quality can reach use demands.
