【摘要】 为了纺制出特殊结构和性能的细号竹节纱,将长短复合纺纱技术和竹节纱纺制技术结合起来开发出了长短复合纺细号竹节纱。通过采用三因素三水平的正交试验设计,优化了长丝与须条间距、长丝预加张力和竹节粗度这三个工艺参数,达到了提高成纱强力、伸长及降低成纱毛羽的目的。更多还原

【Abstract】 To spin fine slubby yarn with special structure and property,long-short complex spinning fine slub yarn was developed through combining long-short complex spinning and slub yarn spinning technology.Three processing parameters i.e.space between filament and sliver,filament pre-tension and slubby thickness were optimized by orthogonal test,the aims of improving yarn strength and elongation,reducing yarn hairiness could be achieved.更多还原
