新型梳棉针布的选型实践

Selection of the New Card Clothing

为了提高纺J 5.83 tex纱和R9.8 tex纱的梳棉质量,分析两种纱线的原料性能、纺纱质量要求及生产难点,确定梳理用针布的选型原则,并对不同纺纯棉、化纤针布型号做了半成品质量试验。通过对比分析,表明应根据纤维性能、纺纱质量要求合理配置针布;纺J 5.83 tex纱应选择浅齿、大工作角、齿密大的锡林针布齿条;纺纯粘胶纤维应比纺化纤针布总高小、工作角大;针布选型时,应重视配套工艺参数并保持针布状态良好。

In order to improve carding quality of yarn J 5.83 tex and R 9.8 tex,analysis is done to the characteristics of the two kinds of yarn, quality requirement and production nodus. The guidance is confirmed for card clothing selection. Semi-production test is done with the varieties of card clothing including pure cotton and synthetic fiber. Comparative analysis proves that proper configuration of card clothing is necessary in conform with fiber performance and yarn quality requirement. Spinning yarn J 5.3 tex requires cylinder wire with superficial wire setting, big work angle, and big wire density while spinning viscose fiber requires card clothing with higher over height and bigger work angle. Process specifications should be taken into serious consideration in card clothing selection for better perform- ance of the card clothing.
