摘　　要：探讨了纺制聚酯/聚丙烯皮芯型复合纤维的生产工艺技术,分析了皮芯型复合纤维的物理指标。结果表明,采用48孔皮芯结构喷丝组件,纺丝速度2 600-3 700 m/min,生产169 dtex/48 f聚酯/聚丙烯皮芯型复合纤维DTY时,侧吹风风速为（0.4-0.6）土0.02 m/s,风温为12-20℃,湿度为60%-80%;加弹纺速400-500 m/min,B/Y比1.3-1.5,变形温度120-135℃,定型温度125-140℃,牵伸比1.3-1.5,可纺制出性能优良的复合型地毯纤维。Di scussed the producing technology of PET/PP core-sheath compound fiber, analyzed the corresponding products performance testing items. Results show that, when using 48 holes spinning pack,spinning speed 2 600 - 3 700 m/min, cross-air blasting speed（ 0. 4 - 0. 6） ± 0. 02 m/s, cross-air blasting temperature 12 - 20 ℃, humidity 60 - 80%, draw texturing speed 400 - 500 m/min, B/Y ratio 1. 3 -1. 5, texturing temperature 120 - 135 ℃, setting temperature 125 - 140 ℃, draw ratio 1. 3 - 1. 5, 169dtex/48 f PET/PP core-sheath DTY fiber was got. Product has fine properties, could be used as composite carpet fiber.
