S向强捻纱的生产技术要点

Key Points of Producing S Hard Twist Yarn

探讨S向强捻纱的生产工艺。通过在不同细纱机型实施捻向改动的技术措施,正确设定细纱速度、捻度等工艺参数,合理选配钢领、钢丝圈及使用周期,自动络筒机更换S捻捻接器专用件,正确设定捻接气压、接头长度,采用二次蒸纱工艺,加强锭子清洁及S捻操作,成功生产出T/R 80/20 19.7 tex、CJ 7.29 tex S向强捻纱,满足了使用要求。

Production processing of S hard twist yarn was discussed. Technology measures of changing twist direction were used in different model spinning frames, processing parameter of spinning speed and twist were set correctly, ring, ring traveler and their using periods were selected rationally, S twist splicer was used in automatic winder, splicer air pressure and joint length were set correctly,twice steaming yarn processing was used,spindle cleaning and S twist operation were strengthened, finally T/R 80/20 19.7 tex and CJ 7.29 tex S hard twist yarn could be produced successfully, the yarn qualities could reach use demands.
