锡林针布齿深对涤纶纱质量影响的分析

Analysis on the Effect of Tooth-Depth of Cylinder Card Cloth on Polyester Yarn Quality

研究了不同梳棉机产量下锡林齿深对涤纶纱质量的影响问题。分别采用两种齿深的锡林针布,各自在梳棉机两种出条速度条件下进行梳理对比试验,并采用同样的后序工艺纺制成纱,对纱线条干、强力和毛羽指标分别进行检测。结果表明,锡林针布齿深对纱线质量是有影响的,总体上认为0.4 mm齿深更加有利于纱线条干和强力指标的改善,而浅齿(0.3 mm)对毛羽指标比较有利;器材的选配对成纱各方面指标的影响可能会有差异,这时需要结合产量、加工原料及具体的客户需求进行优化选择。

The Effect of cylinder tooth-depth under different carding machine output on polyester yarn quality was studied.Two kinds of cylinder card cloth with different tooth-depth were compared by carding experiment under two output conditions.The yarn was produced with the same subsequent process.The yarn evenness,strength and hairiness index were tested.The results showed that the tooth-depth of cylinder card cloth had some effect on yarn quality.0.4 mm tooth-depth was more conducive to improving yarn quality in evenness and strength generally,and 0.3 mm tooth-depth was beneficial to hairiness index.The selection of appropriate equipment might influence yarn index.It is necessary to optimize and choose equipment according to output,materials and customer demand.
