摘　　要：在EJM128K型环锭细纱机上加装PLC控制的伺服电动机进行机械改造,生产高精度竹节纱。通过分析竹节纱生产控制系统的传递函数,确定该闭环控制系统在控制竹节长度参数上具有稳定性、精确性和快速性的特征。用USTERTESTER5测量该系统纺制的竹节纱,获得竹节长度和竹节间距分布图。分析了竹节长度设定值、竹节纱捻系数、原料种类等对竹节长度偏差的影响。研究结果对生产实践中有效控制竹节纱长度和纺制高精度的竹节纱具有参考作用。High-precision slub yarns were produced by EJM128K type ring spinning frame which had been equipped with PLC controlled servomotor.By analyzing the transfer function of the control system of slub yarn production,it was asserted that this close loop control system possess the characteristics of stability,precision and rapidity in controlling the parameters of slub length.USTER TESTER5 was used to test the slub yarns produced on the system and the distribution curve of slub length and slub space was attained.The influence of the preset slub length,twist factor,and material types on the deflection of slub length was investigated.These findings offer reference for effective control of slub length and production of high quality slub yarns.
