摘　　要：为了解决转杯纺涤棉混纺纱断头率高、纱线强力低、长毛羽多、纤维缠绕分梳辊针布等问题,介绍其纺纱特点、存在问题,及假捻盘、转杯、分梳辊等关键器材的作用与要求;对比分析不同转杯纺涤棉混纺纱关键器材选配和工艺优化前后的成纱质量,详细阐述其选配原则和要点。指出:采用大直径T型槽转杯、螺旋陶瓷钢支架假捻盘,转杯低速度配置,分梳辊中速度配置,转杯大负压设置,排杂小负压设置等措施,可使用低级棉纺制转杯纺涤棉混纺纱,条干均匀、疵点少、强力好,成纱质量稳定,成本降低且绿色环保,生产效率提高。In order to solve the problems such as high break rate,low strength of yarn,excessive long hairiness,fiber winding carding roller and so on of polyester cotton blended yarn,the spinning characteristics,existing problems,and the functions and requirements of key accessories such as false twister navel,rotor and carding roller are introduced.The yarn quality before and after the key accessories selection and process optimization of different rotors spun polyester cotton blended yarn are compared and analyzed,and its selection principle and key points are described in detail.It is pointed out that the low grade cotton can be used to spin polyester cotton blended yarn in rotor spinning with the measures of large diameter T-groove rotor,spiral ceramic steel bracket false twister navel,low speed of rotor,middle speed of carding roller,large negative pressure of rotor and small negative pressure of discharging impurities.The blended yarn is evenness and has less defects,good strength.The yarn quality is stable,the cost is reduced and green environmental protection,the production efficiency is improved.
