摘要(Abstract)：
研究了聚酯熔体直接纺中熔体端羧基含量、熔体含杂量及熔体特性黏度偏差对生产的影响,提出了可行的对策。结合熔体输送、纺丝温度、纺丝组件、缓冷器应用、冷却、集束及上油工艺条件,在常规熔体直接纺生产线上成功地生产出高质量微细旦POY。
The influence ofcarboxylend group content,meltim purity contentand meltintrinsic viscosity deviation on the production of PET melt direct spinning were discussed. The feasible countermeasure was also introduced. Combined with the melt transfer, spinning temperature, spinning package, quench air blow, cluster and the finish process conditions, high quality of micro-fine denier POY could be successfully produced on convention melt direct spinning production line.
