摘　　要：为了开发天然彩棉/细绒棉混纺纱,依据原料性能确定CJ 14.6 tex混纺针织纱配棉比例、工艺流程,对其清梳联、并粗、精梳、细纱、络筒工序的工艺参数进行优化。通过对比优化前后的成纱质量指标,表明:使用30%天然彩棉(棕色)和70%普通细绒棉纺CJ 14.6 tex混纺针织纱,须遵循减少纤维损伤的工艺原则;梳棉工艺对纱线质量影响较大,应采用锋利度好、耐磨性佳的优质针布以增强分梳、减少纤维损伤;优化各工序工艺参数,合理控制车间温湿度以及加强管理后,成纱条干CV值明显改善,100 km纱疵减少,生产效率提高。In order to develop natural colored cotton/medium cotton blended yarn,the blended ratio and process flow of CJ 14.6 tex blended knitted yarn are determined according to the properties of raw materials,and the process parameters of blowing-carding unit,drawing and roving,combing,spinning and winding are optimized.By comparing the yarn quality indexes before and after optimization,it is shown that the process principle of reducing fiber damage should be followed when 30%natural colored cotton(brown)and 70%ordinary medium cotton are used to spin CJ 14.6 tex blended knitting yarn.Carding process has a great influence on yarn quality,and high quality card clothing with good sharpness and wear resistance should be used to enhance carding and reduce fiber damage.After optimizing the process parameters of each process,rationally controlling the temperature and humidity of the workshop and strengthening the management,the CV value of the finished yarn is obviously improved,the 100 km yarn defects are reduced and the production efficiency is increased.
