摘要:为了在涡流纺生产中试验和推广优势重定量纺纱工艺,提高成纱质量、减少前纺机台配置并降低生产成本,以涡流纺生产R 19.7 tex纱为例,详细介绍各工序工艺配置要点并优化相关参数;通过优化前后成纱质量对比,说明:清花工序柔和开松,可减少纤维损伤;梳棉工序实现了生条重定量条件下的“柔性梳理”;并条工序采用低并合、小牵伸、慢速度,实现了“柔性牵伸”并提升了纤维的伸直平行度。指出:采用优势重定量工艺后,纱线指标明显改善,半制品定量增加25%时,VORTEX 870 EX型涡流纺纱机速度达540 m/min,生产效率达99%以上。

Abstract:In order to test and promote the heavy weight per unit process in vortex spinning production, improve the yarn quality, reduce the configuration of the front spinning machine and reduce the production cost,the vortex spinning R 19.7 tex yarn is taken as an example to introduce the key points of the process configuration and optimize the related parameters.Through the comparison of yarn quality before and after optimization,it is shown that the soft opening of the cleaning process can reduce the fiber damage;the carding process realizes the “flexible carding” under the condition of heavy weight per unit of card slive.The drawing process adopts low blending,small drafting and slow speed to achieve “flexible drafting” and improve the fibers’ straight parallelism.It is pointed out that the yarn index can be improved obviously by using the heavy weight per unit technology.When the heavy weight per unit of half product is increased by 25%,the speed of the VORTEX 870 EX spinning machine can reach 540 m/min and the production efficiency is over 99%. 
Key Words:heavy weight per unit;vortex spinning;viscose;dominant spinning process;flexible carding;straight parallelism;temperature and humidity
