摘　　要：探讨喷气涡流纺纱机涡流管结构的优化设计。对涡流管的内部结构和喷气孔射流空间形状进行了优化设计,以粘胶纤维为原料在喷气涡流纺纱小样机上进行了几种纺纱试验,对成纱质量指标进行了对比分析。认为:涡流管结构应选用三段式内部结构,封闭或者交叉封闭形式的涡流管喷气孔射流形状可以改善成纱质量。Design and optimization of vortex tube in air jet vortex spinning frame were discussed. Inner structure of vortex tube and air jet flow shape was optimized. Taking viscose fiber as raw material, several spinning tests were carried out in air jet vortex sample spinning frame, the yarn quality was contrasted and analyzed. It is considered that three-stage inner structure should be adopted for vortex tube. Yarn quality can be improved when air jet flow shape of vortex tube is closed style or cross-closed style.
