摘　　要：以环吹冷却方式生产聚酯粗旦纤维易出现染色质量问题。采用中纺院柔性化五釜工艺,配合巴马格最先进EVO环吹技术及12头纺WINGS-POY卷绕机,从无风区、风压、导流插板、风筒直径等因素不断优化工艺,最终生产出质量稳定、染色M率高的粗旦纤维,并得到市场认可。The dyeing quality problem of coarse denier polyester fiber produced by ring blowing cooling is easy to occur.Using the flexible five-autoclaves process of China Textile Institute,with the most advanced EVO ring blowing technology and 12 spinning WINGS-POY winding machine of Barmag,the processes are continuously optimized from the factors of windless zone,wind pressure,deflecting plate,duct diameter,and so on,and finally the coarse denier fiber with stable quality and high dyeing M rate is obtained by the market.
