摘　　要：采用母粒添加注射机及共混熔融方式，在聚己内酰胺（PA 6）切片中加入防霉除味母粒，通过异形及低温纺丝技术制备出长效防霉除味吸湿 PA 6纤维，对其生产工艺进行了探讨。结果表明：在纺丝温度250-252℃，侧吹风速度0．40-0．50 m／min，纺丝速度4000-4200 m／min，采用十字异形喷丝板，组件起始压力13 MPa，加弹速度600-650 m／min，上油率1．4％-1．8％时，生产稳定性较好，生产的78 dtex／24 f PA 6假捻变形丝具有良好的力学性能及防霉、除味、吸湿性能；纤维断裂强度4．12 cN／dtex，断裂伸长率30．1％，防霉等级1级，氨气消除率99％，醋酸消除率95％，水滴扩散面积10．8 cm^2／min，织物芯吸高度12．4cm／h。A long-acting mildewproofing deodorant hygroscopic polycaprolactam （PA 6） fiber was prepared by melt blending a mildewproofing deodorant agent with PA 6 chip on a masterbatch injection machine via low-temperature profile spinning process . The production process was discussed .The results showed that the production proceeded smoothly under the conditions as fol -lowed：spinning temperature 250-252 ℃, cross air speed 0.40-0.50 m/min, spinning speed 4 000-4 200 m/min, cross profiled spinneret, initial pressure of spinning pack 13 MPa, texturing speed 600-650 m/min, oil pick up 1.4%-1.8%;the obtained 78 dtex/24 f PA 6 draw textured yarn exhibited favorable mechanical properties and mildewproofing deodorant hygroscop -ic properties, comprising the breaking strength 4.12 cN/dtex, elongation at break 30.1%, mildewproofing grade 1, ammonia re-moval rate 99%, acetic acid removal rate 95%, droplet diffusion area 10.8 m^2/min, fabric core suction height 12.4 cm/h.
