摘　　要：探讨粘胶竹节包缠纱的工艺优化措施。选择粘胶纤维竹节纱作为芯纱,涤纶长丝作为外包纤维,通过原料各组分占比的确定,重点优化后纺工艺的配置。合理定位涤纶长丝和粘胶纤维须条的位置,优选涤纶长丝的张力,设置合理的捻系数,解决了节粗4.0倍的竹节包缠纱生产困难和包缠效果不佳的问题。实践证明:涤纶长丝含量在25%~35%、长丝在粘胶纤维须条右边的1/3处,长丝张力控制在1.02倍~1.03倍,捻系数在350左右时,粘胶纤维/涤纶长丝42.2 tex竹节包缠纱的成纱质量指标、包缠效果和产量均达到用户的要求。认为:细纱工艺改进以及设备改造可以实现粘胶竹节包缠纱的顺利纺制和质量要求。Processing optimization measure of viscose slub wrapped yarn were discussed.Viscose fiber slub yarn was selected as core yarn,polyester filament was selected as outer wrapped fiber.Through determination of each component proportion in the raw material,configuration of post-spinning processing was emphatically optimized.Positions of polyester filament and viscose fiber sliver were reasonably located,tension of the polyester filament was optimized and reasonable twist factor was set,which solved the problems of difficulty in production of slub wrapped yarn with 4.0 times slub and worse wrapping effect.Practice had proved that when the content of polyester filament was 25%~35%,the filament was at the right 1/3 of viscose fiber sliver,filament tension was controlled at 1.02 times to 1.03 times,twist factor was about 350,quality index,wrapping effect and output of viscose fiber/polyester filament 42.2 tex slub wrapped yarn were all reached requirements of users.It is considered that improvement of spinning technology and equipment modification can realize successful spinning and quality requirements of viscose slub wrapped yarn.
