Effect of the novel taker-in on the quality of card slivers and yarns of polyester was studied. The content of short fibers and neps of the card slivers processed at different operation speeds of the taker-in and saw-tooth taker-in was examined by type Y111 roller fiber length tester and visual evaluation. YG ( B)021DX table type electronic single yarn strength tester and Premier yarn evenness tester were used to test the strength and yam evenness of the yarns processed by the taker-in and saw-tooth taker-in. Test results showed that the card slivers processed by the taker-in exhibited less neps and short fiebrs than those by saw-tooth taker-in; the quality of yarns produced by using the taker-in, such as parameters of yarn evenness, yarn defects, breaking elongation, and so on, was better than that by saw-tooth taker-in, especially the parameters of yarn strength and strength CV value. It is concluded that the novel taker-in leads to less fiber damage and lower nep content, this may be attributed to its smooth surface without edge, and smaller tooth-top area.%研究新型梳针刺辊对涤纶生条和纱线质量的影响.用Y111型罗拉式纤维长度分析仪和棉条目检法检测了梳针刺锯和锯齿刺辊在不同速度条件下所加工生条中的短绒和棉结,用YG(B)021DX台式电子单纱强力仪和Premier条干仪对梳针和锯齿刺辊所加工的纱线进行强力和条干检测.结果发现,梳针刺辊加工的生条其棉结和短绒要比锯齿刺辊少,梳针刺辊所加工的纱线其条干、常发性纱疵、伸长等质量指标要好于锯齿刺辊,在强力及强力CV值的质量指标上梳针刺辊明显优于锯齿刺辊.分析认为梳针表面光滑、没有棱角、齿顶面积小是梳针刺辊对纤维损伤小、去除棉结效果好的主要原因.
