摘　　要：为分析喷气织机引纬过程中纬纱进入筘槽段内的运动状态,减少纬纱飞行过程中卷曲、飘动等不利运动情况,通过优化引纬工艺参数,搭建纬纱运动特性观测实验平台,利用高速摄影技术对纬纱飞入筘槽部分进行拍摄研究,获得气流特性与纬纱运动速度、加速度等参数之间的关系。实验结果表明,当主喷压力为0.3 MPa、主喷嘴出口距筘槽长度为20 mm,主喷嘴出口距第一辅喷嘴距离为50 mm时,织造能耗小,纬纱波动小,引纬效率高。研究结果为实际生产提供了参考。To further learn the motion state of weft yarn insertion of the air-jet loom, the adverse movements of reducing weft crimp, and fluttering ete in the process of weft flying, the weft yarn insertion process parameters were optimized. The weft insertion motion experimental platform was adopted, and the characteristics of the weft yarn motion were filmed by using the high-speed photography technology, and then the relationships of parameters between the airflow characteristics and the weft yarn velocity, acceleration and efficiency etc were given. Experiment results show that when the main injection pressure is 0. 3 MPa, the distance between the main nozzle outlet and the profiled reed is 20 ram, and the distance between the main nozzle outlet and the first relay nozzle is 50 ram. The energy consumption and weft yarn fluctuation are small, and the production efficiency is high. The production. above research results provide reference to the actual
