Cotton sliver quality monitor and modification in USG assistance were discussed. According to characteristic of spinning enterprises relying on relative small finisher drawframes to process fiber, key parts of finisher draw-frames to modify sliver quality ami control qulaity were put forward, lister Sliver Guard was used. Importance of the system in finisher drawframe to realize auto leveler and quality monitor were discussed. Through the test it is proved that the system can reduce sliver long-term mass variation and thick places obviously,better quality control can be realized.%探讨USG辅助下的棉条质量监控与改进.针对纺纱企业依靠数量相对较少的末道并条机集中加工纤维的特点,提出末道并条是改进棉条质量变异和进行质量控制的关键部位.通过引入Uster Sliver Guard,论述了该系统在末并工序进行自调匀整和棉条质量监控的重要性,并试验性地证明了使用该系统可以显著减少棉条长片段不匀及粗节,实现更可靠的纺纱质量控制.
