摘要:为适应新型纤维及纺纱技术的发展,介绍新型纤维和纱线品种及其对牵伸下罗拉的新要求,分析免校直易装罗拉、集聚纺密齿罗拉、三元色纺罗拉和8锭超长车抗扭罗拉的研发关键、优点及用户使用情况。指出:随着新型纤维及纱线品种的不断涌现,研制适应市场需求的新型罗拉势在必行;免校直易装罗拉配套经纬细纱主机使用,纺纱指标可达2013乌斯特公报5%水平,且纺制混纺、粘胶、天丝等新型纤维时无腐蚀生锈问题;集聚纺密齿罗拉纺特细号纱成纱条干CV值和CVb值同比提高0.2个百分点;三元色纺罗拉可满足个性化纺纱需求;8锭超长车抗扭罗拉适应重定量、大牵伸工艺,安装方便且能减少主机备件数量;新型罗拉为纺企节省用工,提质、降本、增效创造良好条件。

Abstract:In order to cater to the development of new fibers and spinning technology,the varieties of new fibers and yarns and their new requirements for bottom rollers for drafting are introduced together with the analysis of the key points of the research and development,advantages and user feeding-back of the free-straightening easy-to-install rollers,densely-toothed rollers for compact spinning,ternary color spinning rollers and torsion-resistant rollers on 8-spindle long frames.It is pointed out that with the continuous emergence of new fibers and yarn varieties,it is imperative to develop new rollers to meet the market demand;the use of free-straightening and easy-to-install rollers of Jingwei spinning frames can achieve 5% spinning index of the 2013 Uster bulletin,and there is no corrosion and rust problem in spinning new fibers such as blended,viscose and tencel;the CV value and CVb value of yarn evenness of densely-toothed rollers of compact spinning extra-fine yarn increases by 0.2 percentage point over the same period of last year;ternary color spinning rollers can meet individual spinning demand;torsional roller on 8-spindle long frame is applicable in heavy weight and large drafting process,which is easy to install and can reduce the number of spare parts of frames;the new rollers provide good conditions for textile enterprises to save labor,improve quality,reduce cost and increase efficiency.
Key Words:new fiber;blended yarn;roller;compact spinning;densely-toothed;evenness;ternary color spinning;torsional vibration;long frame
