摘　　要：文章详尽介绍了三通道数码环锭纺纱机传动系统及控制系统的组成及工作原理,分析了在线和离线调控混纺比、线密度及捻度的机理,构建了纺制任意比例混色纱、色彩分段分布的段彩纱、混纺比渐变分布的渐变色纱、混纺比不变的竹节纱以及混纺比和粗细均变化的段彩竹节纱等5类花色纱线的纺纱方法。最后指出,三通道数码纺纱机通过调控3个通道的牵伸比(e_m、e_y、e_c)及锭子速度,达到纱线线密度、混纺比及纱线捻度可调控的目的,进而实现对纱线外观形态及结构的调控,使环锭纺纱机具有纱线成形与色彩调控的双功能,实现了对传统纺纱工艺的重大突破。The paper detailed introduces the components and principle of drive system and control system of ring-spun three-channel digital spinning machine,analyzes the mechanism of on-line and off-line regulation of yarn blending ratio,linear density and twist,and establishes methods of spinning of five fancy yarns,i.e.,mélange,segment colored yarn,gradient colored yarn,slub yarn,and segment colored slub yarn.In the end,the paper points out that the three-channel digital spinning machine can regulate and control yarn linear density,yarn blending ratio,and twist via regulate the draft ratios of three channels,that is,em,ey,ec,and spindle speed,so as to regulate and control the yarn appearance and structure,endow ring-spinning frame with double functions of yarn forming and color control.Three-channel digital spinning technology is a breakthrough of traditional spinning process.
