梳棉棉结的控制

Study on Control of Nep in Carding Cotton

梳棉棉结一直是困扰纺纱企业的难题。通过刺辊速度、锡林速度、梳棉机出条速度、梳棉机定量、活动盖板速度的正交试验,得出对棉结影响的主次顺序和最优方案,并验证了最优方案是最优工艺。最优工艺为刺辊速度770 r/min、锡林速度560 r/min、盖板速度300 r/min、生条定量4.6 ktex、出条速度140 m/min。研究结果为控制梳棉棉结提供了控制方法。

Carding cotton nep has always been a difficult problem for spinning enterprises.In this paper,through the orthogonal test of the speed of pricking roller,cylinder speed,carding machine stripping speed,carding machine quantity and moving cover plate speed,the primary and secondary order and the optimal scheme of the influence on the nep are obtained,and the optimal scheme is verified to be the optimal process.The optimal process is roller speed 770r/min,cylinder speed 560r/min.cover speed 300r/min,strip quantity 4.6Ktex.strip speed 140m/min.The rescarch results provide a control method for carding nep.
