摘　　要：讨论了聚酯熔体中杂质颗粒、熔体温度、纺丝组件、侧吹风速度、上油方式、拉伸倍数与热辊温度等因素对涤纶细旦丝的影响。结果表明:降低聚酯熔体中的杂质颗粒直径,选择熔体温度280-282℃,纺丝温度290-292℃,侧吹风速度约4．5 m／s,纺丝组件压力13．0-14．0 MPa,采用油嘴上油,拉伸倍数2．3-2．5, 拉伸温度90-94℃,定型温度128-130℃,可生产出性能优良的110 dtex／144 f涤纶FDY细旦丝。The effects of impurity particles in polyester melt, melt temperature, spin pack, cross air blow speed, oiling method, draw ratio and heat roll temperature on the quality of fine denier PET fiber were discussed. The results showed that the 110 dtex/144 f fine denier PET FDY with splendid properties can be produced by decreasing impurity particle size, using nipple oiling method and selecting melt temperature 280 -282℃, spinning temperature 290 -292℃, cross air blow speed about 4.5 m/s, spin pack pressure 13.0 - 14.0 MPa, draw ratio 2.3 -2.5 ,drawing temperature 90 -94℃, setting temperature 128 - 130℃.
