摘　　要：分析探讨了纺制PET/PA6米字型POY复合纤维的生产工艺,组分质量比PET∶PA6为82∶18,结果表明,当纺丝温度PET为285~295℃,PA6为260~270℃,箱体温度为265~292℃,纺丝速度为2 900~3 200 m/min,侧吹风速为0.40~0.65 m/min,风温为18~22℃时,可纺制出性能较好的POY用于后道加工,所得纤维的规格为285 dtex/72 f,断裂强度(2.3±0.2)c N/dtex,断裂伸长率(135±5)%。Discussed the producing technology of PET/PA6 splitable composite fiber. Results showed that, mass ratio PET ： PA6 was 82 ： 18, when PET PA6 melt spinning temperature were 285 - 295 ℃ and 260 270 %, spinning head temperature was 265 - 292 ℃, spinning speed was 2 900 - 3 200 ndmin, side blowing wind speed was 0. 40 - 0. 65 m/min, wind temperature was 18 - 22 ℃, good performance splitable composite fiber was got, product specification was 285 dtex/72 f, breaking strength was （2. 3±0. 2） cN/dtex, breaking elongation was （135±5） %.
