摘　　要：研究循环再生棉纱原料的工艺优化措施,并制定产品质量控制标准。简述了再生棉原料的来源和分类,确定加工再生棉的标准,依据纤维损伤最少的原则,利用纺纱、织布、服装加工生产过程中产生的边角料或废纱经再加工制得的再生纤维为再生原料,优化原料工艺流程,优选关键设备,制定原料退色、烘干工艺,进行再生棉纱生产试验,从而确定产品适应性范围,制定出再生棉纱品质控制标准。认为:生产28.1 tex^59.1 tex转杯纱,再生棉配比控制在30%~80%较适宜;生产18.5 tex^28.1 tex环锭纱,再生棉配比控制在20%~50%较合适;生产11.8 tex^14.8 tex精梳集聚纱,再生棉配比控制在30%内可以达到生产标准。Process optimization measures of recycled regenerated cotton yarn raw materials were studied and product quality control standards were formulated.Source and classification of regenerated cotton raw materials were briefly described,standard for processing regenerated cotton was determined.According to the principle of minimum fiber damage,regenerated fibers made from reprocessing of scraps or waste yarns produced during spinning,weaving and garment processing were used as regenerated raw material.Raw material process and key equipment were opti⁃mized.Processes of fading and drying of raw materials were formulated.Production test of regenerated cotton yarn was carried out,so as to determine product adaptability range and formulate quality control standards for regenerated cotton yarn.It is considered that ratio of regenerated cotton is suitably controlled in 30%~80%when producing 28.1 tex^59.1 tex rotor yarn.Ratio of regenerated cotton is suitably controlled in 20%~50%when producing 18.5 tex^28.1 tex ring yarn.Ratio of regenerated cotton is suitably controlled below 30%when producing 11.8 tex^14.8 tex combed condensed yarn.
