Abstract
Spinning processing of siro spinning installing pressure bar spacer was discussed. According to the problem of siro spinning roving lighter weight per unit and supply ability shortage, in condition of increasing siro spinning roving weight per unit, profiled pressure bar spacer was adopted, roving twist factor was reduced properly, spinning gauge,pressure,rubber-covered roll position et al were adjusted,yarn draft problem caused by installing pressure bar spacer was solved. Yarn quality could be improved,supply capacity could be improved and production cost could be reduced. But bobbin yarn 3 mm hairiness and A3 grade yarn defects were increased and need to be improved.关键词
