摘　　要：为了减少毛巾织造过程中毛经纱张力波动,课题组以布动式毛巾织机为对象,运用几何分析方法,定量地分析了布动式毛巾织机布面移动、开口运动和打纬运动对毛经纱路径变化规律的影响;以织造过程中毛巾纱张力恒定为目标,获取了毛经活动后梁的理想位置。结果表明:毛经活动后梁的位置变化可以弥补起毛运动、开口运动和打纬运动对毛经纱张力变化产生的影响。根据研究结果,提出了几种毛经活动后梁的位置控制方式,并分析了相应的优缺点,为工程上设计毛巾织机张力调节和控制系统提供参考。In order to reduce the fluctuation of wool and warp yarn tension during towel weaving,research group took the cloth towel loom as the object and used geometric analysis method to quantitatively analyze the influence of cloth cover movement,opening movement and beating-up movement on the change rule of wool and warp yarn path,aiming at the constant towel yarn tension during weaving to obtain the ideal position of the movable back beam of wool and warp yarn.The results show that several position control methods of the back tension beam of the warp yarn are proposed,and the corresponding advantages and disadvantages provide reference for the design of the towel loom tension adjustment and control system.
