摘　　要：为探究旋流喷嘴气道配置不同对减少环锭细纱毛羽效果的影响,设计和使用了2组不同气道直径和气道位置的旋流喷嘴进行纺纱实验,并对采用普通环锭纺、集聚纺和旋流纺的纱线综合性能进行了比较。结果表明:当旋流喷嘴的气道直径为1.4 mm时,其减少毛羽的效果比1.2 mm和1.6 mm时好,当气道位置为1∶2时,其减少毛羽的效果优于位置为1∶1和2∶1的旋流喷嘴。得出旋流喷嘴最佳气道配置:直径为1.4 mm,位置为1∶2,最佳加工气压为0.15 MPa,在此条件下,旋流纺比普通环锭纺纱线的毛羽指数降低了76.5%,断裂强度增加了5.4%;比集聚纺纱线的毛羽指数降低了64.4%,断裂强度降低了4.0%,减少毛羽效果显著。In order to research the effect of different airway structures of a swirl nozzle on reducing yarn hairiness,two groups of swirl nozzles with different airway diameters and airway positions were designed in this paper.The comprehensive performance indexes of yarn were tested and conducted for comparison with the conventional ring spinning and compact spinning.The results showed that the swirl nozzle with1.4 mm airway diameter was superior to the other two swirl nozzles with airway diameter of 1.2 mm and1.6 mm,respectively.Airway position of 1∶ 2 is better than 1∶ 1 and 2∶ 1.Thus the optimum conditions to reduce yarn hairiness include swirl nozzle with 1.4 mm airway diameter,1 ∶ 2 airway position,and pressure of 0.15 MPa.Under this condition,compared with that conventional ring spun yarn,the hairiness index was reduced by 76.5%,and breaking strength was increased by 5.4%.Compared with that of compact spun yarn,the hairiness index was reduced by 64.4%,and breaking strength was decreased by 4.0%.As a result,the effect on reducing hairiness was remarkable.
