摘要
探讨粘胶强捻纱的关键生产工艺。介绍了粘胶强捻纱的特点和质量要求,在实践中对关键工艺进行了优化:清梳联工序采用短流程、低速度、锡林刺辊大速比、柔性分梳;并条工序采用主区强控制、后区大隔距大牵伸倍数;粗纱工序采用中定量、大粗纱捻系数;细纱工序采用前区适度隔距、后区大隔距、小后区牵伸倍数;络筒采用低速度、适度张力等工艺措施,定形采用加热定形或自然回潮定捻,温湿度管理重点控制加湿不匀。通过上述措施,能够达到粘胶强捻纱质量好、纱疵少、织机效率高的要求。
Key production process of viscose hard twist yarn was discussed.Properties and quality requirements of viscose hard twist yarn were introduced.Key process was optimized in practice.Short process,lower speed,larger speed ratio of cylinder & licker-in and softer carding were adoptted in blowing-carding process.Stronger control in main zone,larger gauge and larger drafting factor in back zone were adoptted in drawing process.Medium weight per unit and larger roving twist factor were adoptted in roving process.Moderate gauge in the front zone,larger gauge and smaller drafting factor in back zone were adoptted in spinning process.Lower speed and moderate tension were adoptted in winding process.Heat setting or natural regaining was selected as setting,uneven humidification was controlled by temperature and humidity management.Through adopting the above measures,it is possible to achieve the requirements of better viscose hard twist yarn quality,less yarn defect and higher weaving efficiency.
