摘　　要：以聚己内酰胺(PA6)为皮层材料,聚对苯二甲酸乙二醇酯(PET)为芯层材料,纺制156dtex/48 f的皮芯型涤锦复合纤维。经过试验,选择皮芯复合比例为40/60,PA6螺杆温度255~265℃,PET螺杆温度285~295℃,侧吹风风速0.4~0.5 m/s,风温21~23℃,拉伸温度75~85℃,热定型温度115~130℃,牵伸比2.5~2.8,纺丝速度4 245 m/min,通过试验能得到性能与常规纯PA6纤维接近的复合纤维。Used polycaprolactam （PA6） as skin phase, polyethylene terephthalate （PET） as core phase, spun PA6/PET core-sheath composite fiber. Results show that, when the ratio of skin to core is 40/60, PA6 extruder’s temperature is between 255 -265 ℃, PET extruder’s temperature is between 285 -295 ℃, cross-air blasting temperature is between 21-23 ℃, drawing temperature is between 75 -85 ℃, heat setting temperature is between 115 -130 ℃, drawing ratio is between 2. 5-2. 8, spinning speed is 4 245 m/min, PET/ PA6 core -sheath composite fiber is got, which has properties approach to general polyamide fiber.
