摘　　要：为了提高机采棉制成率,介绍机采棉和手摘棉质量差异以及机采棉纺纱存在的问题,详述在清花工序优化工艺参数、在梳棉工序使用高齿密锡林、刺辊、盖板针布,解决机采棉棉结、带纤维籽屑、短纤维率高等导致用棉成本大、半制品质量差等问题的具体措施。通过纺纱实例测试对比,指出:使用机采棉,清花工序一般采用先开后打、大杂早落、小碎多落、多梳少打的工艺原则,以加强开松、除杂、混和和梳理,防止过度打击而损伤纤维;梳棉工序使用高齿密针布,除杂、开松效果明显改善,落棉率降低且成纱质量改善;用好机采棉,应充分发挥清梳联设备作用,在持续抓好设备、原料、工艺、操作管理的同时,大胆尝试新的梳理器材。In order to improve the production rate of machine-picked cotton,the quality difference between machine-picked cotton and hand-picked cotton,and the problems existing in machine-picked cotton spinning are introduced.The specific measures to optimize the process parameters in the clearing process,the use of high tooth density cylinder,taker-in and flat card clothing in the carding process,and to solve the problems of large cotton cost and poor quality of semi-products caused by high neps,fiber seed and short fiber content in machine-picked cotton are described in detail.Through the test and comparison of the spinning examples,it is pointed out that the process of using machine-picked cotton generally adopts the principles of opening first and beating later,large impurities falling early,small fragments falling more,more combing and less beating,in order to strengthen opening,removing impurities,mixing and carding,and prevent excessive damage to the fiber.When the high tooth density card clothing is used in the carding process,the effect of impurity removal and opening is obviously improved,the waste percentage is reduced and the yarn quality is improved.To use the machine-picked cotton well,we should give full play to the role of blowing-carding unit,and boldly try new carding accessories while continuing to grasp the equipment,raw materials,process and operation management.
