摘　　要：变捻纱是采用特殊纺纱工艺生产的一种具有独特结构的纱线。文章通过在四罗拉赛络紧密纺细纱机上进行设备改造,断开原有细纱机牵伸机构与加捻卷绕机构之间的传动,加装一台伺服电机,由伺服电机传动牵伸机构,细纱机原电机驱动加捻卷绕机构,由PLC电脑程序控制伺服电机转速按照工艺设定的要求变化,实现了纱支不变、捻度沿轴向发生变化的特殊风格变捻纱生产。由于纱线的捻度对其光泽、染色性能等有较大影响,通过捻度的变化,在织造和染色整理后,面料会产生特殊的色泽变化,适用于加工特殊风格的面料。The variable twisted yarn researched and developed in this paper is a kind of yarn with a unique structure produced by a special spinning process.By transforming the four-roller siro-compact spinning frame,the research disconnected the drafting system of the spinning machine as well as the twisting and winding system.Adding a servomotor to drive the drafting system;the twisting and winding system is driven by the motor of the spinning frame;using the PLC computer program to control the servomotor speed in accordance with the requirements of the process.In doing so,variable twisted yarns with unchanged yarn count and changed twists along the axial direction can be produced.Since the twist of the yarn has a great influence on its luster,dyeing performance,etc.,after weaving and dyeing,the fabric will show a special color change through the change of twist,which is suitable for producing special-style fabrics.
