Abstract
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.关键词
