| 摘 要： | 分析了细纱牵伸区附加压力棒的作用原理,通过在V型牵伸形式上使用后区附加单压力棒上销和在后区为平面牵伸的机型上使用前区附加压力棒隔距块来进行CJ14.5 tex纱的纺纱试验。试验结果表明:细纱牵伸区附加压力棒后增强了牵伸区内的摩擦力界,加强了对浮游纤维的控制,成纱质量有明显改善,提高了细纱机的牵伸能力。

| Abstract: | The functionary principle of adjunctive pressure bar in the draft area of ring frame was analyzed.CJ14.5tex yarn was spun by using additional single top pin with press bar in back zone of V shape draft arrangement and press bar spacer in front zone.The test shows that adjunctive press bar in draft zone can strengthen draft zone friction field and control the floating fiber.The yarn quality was improved evidently and the draft ability of ring frame was enhanced. |

| Keywords: | press bar draft friction field yarn evenness |
