摘　　要：为了稳定纱条张力,提高成纱质量,降低纺纱断头,分析了细纱机加捻卷绕过程中纱条张力的分布规律,纱条张力与基本卷绕工艺的关系,重点阐述了纺纱张力曲线的变化,纱条张力测试方法、设备、一落纱中典型位置纺纱张力测定示例,及其在细纱变速上的应用。指出:①卷绕过程中纱条张力分布一般规律为TW>T0>TR>TS;②纱条张力与基本卷绕工艺的关系是TR与锭子速度平方(ns2)、钢丝圈重力Gt、钢领半径R(直径DR)成正比;③纺纱张力不是恒值,而是一个不断波动的变量,张力波动和张力脉动是管纱卷装型式客观条件决定的;④由高速摄影记录曲线发现,当纱条转到机台正前方、脱开导纱钩孔眼而悬空时,Tsmax=T0,即在纺纱张力测试时,同时也可测得气圈顶端张力;⑤细纱机上变频调速装置可降低毛羽,调节范围广且节电,纺纱效益好。Aiming for the stable sliver tension, better yarn quality and reduction of yarn breakage, analysis is done to the twisting and winding process of the ring spinning frame regarding the law of the sliver tension distribution,the relationship between the sliver tension and the basic winding. Highlight is given to the curve variation of the tension,the testing method and equipmnt with yarn tension, sampling of the yarn de- termination in the typical location in the process of winding, and the application in the speed regulation of spinning process. Conclusion is made that 1） the law of the sliver tension distribution is as Tw〉T0〉TR〉 Ts in the winding process;2） the relationship between the sliver tension and the basic winding process is as TR in direct proportion to speed square n,2 ,weight of the traveller Gt and the radius of the ring R（diameter Dr） ;3） the yarn tension is a variant instead of a fixed value. The variation and the pulsation of the sliver tension is dependent upon the mode of the bobbin yarn creeling;4） the high speed photographer finds that when the sliver is in the front of the frame, off the hook suspended, Tsmax = To, say, while determination is done to the yarn tension,the top tension of the balloon is gained as well;5） the speed inverter on the frame can lower the hairiness with big range,power economy,and good profit of spinning.
