摘　　要：利用熔体直纺的工艺路线,采用环吹风冷却,成功研制了111dtex/72f三叶异形涤纶全牵伸丝。结果表明,喷丝孔的单叶长宽比4:1,圆形排布等方式,纺丝温度结合组件压力选择在291℃,油轮上油方式,第一热辊温度在130℃的工艺效果较好。产品品质稳定,异形性能好。By using the melt direct spinning process route and the circular blow cooling, 111 dex/72 f trilobal profiled PET FDY was successfully developed. The results showed that the process results are better when the single leaf length-width ratio of spinneret hole is 4 ： 1, the spinneret hole is circular arrangement, the spinning temperature is 291 ℃ ,the oil roller oiliing method is selected and the first hot roller temperature is 130 ℃. The product quality is steady, the profiled performance is better.
