摘　　要：喷气纺是一项旨在提高纺纱速度和灵活性的工艺技术,也称简易纺纱技术。J 20型喷气纺纱机(瑞士立达公司)包含一个由3上3下拉罗组成的高速运转的牵伸装置。纺纱喷嘴中央有一个圆柱形通道(纺纱通道),纱线经牵伸区后需穿过该通道。在倾斜于通道轴线但与其周向相切的方向装有4个喷嘴,压缩空气通过这些喷嘴被注入通道中,形成气体涡流。研究了J 20型喷气纺纱机工艺参数变化对纱线质量的影响。在不同的纺纱工艺参数下,对单纱强度、纱线摩擦因数、纱线不匀率U(%)、纱线疵点和分级试验等质量指标进行了测试。研究表明,经4倍牵伸的纱线具有良好的性能。Air-jet spinning is a technology development intended to increase production speed and flexibility.This technique is also known as fasciated yarn spinning.The air-jet spinning system J 20(Rieter Machine Works Ltd.,Winterthur/Switzerland)consists of a 3-over-3 high-speed roller drafting unit.The air-jet spinning nozzle has a central cylindrical channel(the spinning channel)through which the fiber ribbon from the drafting unit passes.In the air-jet nozzle inclined to the channel axis but tangential to its circumference there are 4 nozzles through which compressed air is injected into the channel,creating vortex airflow.An attempt has been made for the investigation of yarn quality parameters influenced by the variation in the process parameters of the air-jet J 20 spinning machine.The break draft of 4 is found to be optimum.The quality parameters like single yarn strength,yarn friction,yarn U(%),yarn imperfections and Classimat testing has been tested for different machine process parameters.
