摘　　要：利用稀土化合物母粒添加技术生产尼龙6超细旦多孔预取向丝(POY)以及拉伸变形丝(DTY),探讨了稀土化合物母粒含量以及后加工工艺参数对超细旦尼龙6 DTY性能的影响。结果表明:制备46 dtex/72 f多孔尼龙6 POY长丝最佳工艺为纺丝温度255～265℃,纤维中稀土质量分数0.08%,纺丝速度3 800m/min;加弹最佳工艺为拉伸比为1.21,张力为15～16 cN。Porous super-fine nylon 6 preoriented yarn （POY） and draw textured yarn （DTY） were produced by adding rare earth compound masterbatch. The effects of rare earth compound masterbateh content and after-processing parameters on the properties of super-fine nylon 6 DTY were studied. The result showed that the process conditions for preparing 46 dtex/72 f porous nylon 6 POY were optimized as followed： spinning temperature 255 -265 ℃, 0.08% rare earth in fiber by mass fraction, spinning speed 3 800 m/min; and the optimal texturing process was draw ratio 1.21 and tension 15 - 16 cN.
