摘　　要：探讨了远红外细旦丙纶高速纺丝工艺对其可纺性、纤维结构性能的影响 ,研究了远红外 PP-POY的变形工艺。结果表明 ,研制远红外细旦丙纶长丝最佳的纺丝工艺条件为 :纺丝温度 2 5 8℃ ,纺丝速度小于或等于 2 5 0 0 m /min,侧吹风温度 18℃ ,速度 0 .4m/s,集束上油位置距喷丝板 92 0 m m ;最佳的变形工艺条件为 :第一热箱温度 14 5～ 14 8℃ ,第二热箱温度 12 5～ 130℃ ,拉伸比 1.5 6～ 1.5 8,D /Y比1.66～ 1.69,变形速度 42 0～ 45 0 m/m in。The effects of spinning conditions on the spinnability, fiber structure and properties of fine far\|infrared high\|speed spun PP fibers were discussed. The texturizing process for far\|infrared PP\|POY was also studied. The spinning conditions were optimized as follows: spinning temperature 258℃, spinning speed not more than 2 500 m/min, quenching temperature 18℃, quenching speed 0.4 m/s, the distance of 920 mm between collection finish position and spinnerette. The optimal texturizing process parameters were the first heater temperature 145~148 ℃, the second heater temperature 125~130℃, draw ratio 1.56~1.58, D/Y ratio 1.66~1.69, texturizing speed 420~450 m/min.
