R 19.7 tex转杯纱生产实践

摘要

To develop R 19.7 tex rotor yarn,according to viscose fiber characteristics,necessary technology measures were adopted in each process.Processing parameter was tested and optimized including raw material blending ratio,doubling number,draw sliver weight per unit,rotor speed and combing roller speed.Finally R 19.7 tex rotor yarn can be spun successfully,the quality can reach use demands.It is considered that the key rings of spinning fine viscose yarn are adopting larger ratio fine fiber,using three-times doubling,selecting lighter draw sliver weight per unit,optimizing rotor speed and combing roller speed,controlling temperature and humidity well.%为了开发R 19.7 tex转杯纱,针对粘胶纤维特点,在各工序采取必要工艺技术措施,并对原料混配比例、并合道数、熟条定量、转杯速度、分梳辊速度等工艺参数进行了试验优选,顺利纺制出R 19.7 tex转杯纱,较好地满足了使用要求.认为:选用较大比例细特纤维、采用三道并合、较轻熟条定量,优选转杯速度和分梳辊速度,控制好温湿度是纺好细号粘胶转杯纱的几个关键环节.
