摘　　要：采用稀土化合物与PA6切片共混制备稀土化合物母粒,再与PA6切片共混纺丝,开发了超细旦PA6 FDY,探讨了其生产工艺。结果表明:选择纤维中稀土化合物质量分数0.04%,喷丝板孔径0.25 mm,长径比3.0,纺丝温度270℃,纺丝速度4 200 m/min,侧吹风温度30～40℃,湿度40%～60%,生产40 dtex/72 f超细旦PA6 FDY,生产过程稳定,满卷率达90%,纤维断裂强度4.5 cN/dtex,断裂伸长率30%。A rare earth compound was blended with PA6 chips to produce a rare earth compound masterbatch which was blended with PA6 chips and spun into a superfine PA6 FDY.The production process was discussed.The results showed that a superfine PA6 FDY can be produced steadily with the full package rate of 90%,breaking strength 4.5 cN/dtex and elongation at break 30%under the conditions as followed：0.04%rare earth compound by mass fraction in fiber,spinneret diameter 0.25 mm, length-and-diameter ratio 3.0,spinning temperature 270℃,spinning velocity 4 200 m/min,cross air blow temperature 30-40℃,humidity 40%-60%.
