摘　　要：在纺纱过程中,带籽屑棉结(SCN)尽管占棉结比例不大,但对成纱质量却有着重要的影响。用AFIS单纤维测试仪对清梳过程带籽屑棉结的数量和尺寸变化情况进行实验研究,着重研究了梳棉机采用不同道夫与刺辊速度、不同种类的刺辊,梳棉机后罩板采用固定盖板和棉网清洁器不同组合及不同种类的刺辊下固定分梳板对带籽屑棉结去除的影响。结果表明,梳棉机对带籽屑棉结去除是比较有效的,在梳棉过程中可清除60.5%～81.4%的SCN。刺辊的速度、种类、产量对SCN去除有一定的影响,而后罩板和刺辊下固定分梳板及各种吸风装置对SCN去除影响不大。In the course of spinning,SCN(seed coat neps) whose proportion in nep is not large has a great effect on spinning quality.SCN quantity and size in the carding process were tested by using AFIS tester under following conditions, carding machine used different doffer,taker-in, speed and different types of taker-in, carding machine back sheet used stationary flat, web cleaner and carding segment. The experiment results show that carding machine can effectively get rid of SCN by 60 5%～81 4% in the carding process.The speed, type and production of taker-in have a little effect on SCN removal,while back stationary flat,carding segment and all kinds of suction units have little.
