摘要：为纺好新疆机采棉，分析新疆机采棉的特点及加工难点，通过原料配比优化、清花流程控制和梳理工艺优化措施，重点分析清梳联参数优化、针布包卷、各梳理部件隔距配置、针布配置和出条速度的选择。生产实践表明：将机采棉与手采棉合理混用，能有效地解决纺纱中存在的各种问题；清花减少打击，利用清花线打手速度和各落杂区的隔距配置使清花管道气流和棉流通畅；梳理工艺通过提高锡林转速、采用新型大齿密针布、抬高锡林的措施进行参数优化，通过包卷安装针布、检查中曲轨隔距、校验锡林—盖板隔距做好设备状态的维护；同时增加前、后固定盖板配置根数，提高梳棉机的梳理力度；针对不同品种，选用合理的转速。

Abstract:In order to have a smooth production of Xinjiang machine-picked cotton,the characteristics and processing difficulties of Xinjiang machine-picked cotton are analyzed.Through the optimization of raw material ratio,the control of blowing process and the optimization measures of carding process,highlight is given to the optimization of parameters of carding and blowing unit,the binding of card clothing, the configuration of partition of each carding component,the configuration of card clothing and the speed selection of sliver throughput. Production practice shows that proper mixing of Xinjiang machine-picked cotton with hand-picked cotton can effectively solve various problems existing in spinning:beating action can be reduced in blowing process,the air flow and cotton flow can be clear by the adjustment of line speed of the beater and the spacing of each part in the miscellaneous areas. Carding process can be optimized through parameters adjustment such as increasing the speed of cylinder,adopting new clothing with large teeth of heavy setting,and increase the height of the cylinder base.The maintenance of equipments is done by installing card clothing,checking the medium curvature gauge and checking the gauge of cylinder flat,and more,increasing the number of stationary front and rear top flats for height carding strength,and selecting reasonable speed for varieties of products are also necessary.
