摘　　要：优化控制纺丝工艺条件,生产聚己内酰胺(PA 6)预取向丝(POY);然后以PA 6 POY为原料,在德国Barmag公司FK6V-1000型高速拉伸假捻变型机上,控制假捻变形丝(DTY)的生产工艺,生产具有竹节效果的PA 6 DTY竹节丝。结果表明:较低的加工速度及拉伸倍数、较高的热箱温度及D/Y比、合理的超喂率等是生产具有均匀竹节段结构的PA 6 DTY竹节丝的关键;控制加工速度250~300 m/min,拉伸倍数0.80~0.85,热箱温度170~180℃,D/Y比为1.65~1.70,超喂率4.0%~5.8%,可以生产综合性能良好的88 dtex/48 f PA 6 DTY竹节丝,纤维具有竹节段和蓬松段交替分布,竹节长度可达2.53 cm,织物具有镂空感并且吸湿透气性能好。A polycaprolactam （ PA 6） draw textured yarn （DTY） slub yarn was prepared from PA 6 pre-oriented yarn （POY） by rationally control the production processes of PA 6 POY and PA 6 DTY on an FK6V-1000 high-speed draw texturing machine purchased from German Barmag Co.. The results showed that the key to prepare PA 6 DTY slub yarn with uniform slub length was the relatively low texturing speed and draw ratio, relatively high heater temperature and D/Y ratio and proper overfeed ratio ; the PA 6 DTY slub yam of 88 dtex/48 f could be produced with the fairly good comprehensive properties under the conditions of processing speed 250 - 300 m/min, draw ratio 0. 80 - 0.85, heater temperature 170 - 180 ℃ , D/Yratio 1.65 - 1.70, overfeed ratio 4.0% -5.8% ; the obtained fiber exhibited the alternative distribution of slub section and fuzzy section with the slub length of 2.53 cm ; and the fabric was openwork and had good breathability.
