摘要
采用锦纶6一步纺丝法生产锦纶预取向丝(POY),并通过加捻拉伸变形工艺,重点控制热箱温度、拉伸倍数以及加弹速度,制备具有竹节效果的锦纶拉伸变形丝(DTY)。对加弹后的纱线进行织袜及性能测试,结果表明:控制热箱温度为205℃,加弹速度为350 m/min,牵伸倍数为1.05,并合理控制假捻盘片组合、D/Y比及超喂率,可以制备出具有竹节效果的78 dtex/48 PA6 DTY竹节丝,织物镂空效果明显。
The polyamide 6 pre-oriented yarn(POY) was produced by one-step spinning. The draw textured yarn(DTY) with bamboo effect was prepared by the twisting and stretching deformation technology, with emphasis on controlling the heater temperature, the drawing ratio and the stretching speed. The results show that 78 dtex/48 f DTY slub yarn can be prepared by controlling the conditions of heater temperature 205 ℃,heater speed 350 m/min, drawing ratio 1.05, and the combination of false twist discs, the D/Y ratio and overfeed rate at a reasonable level, and the knitted fabric hollow effect is obvious.
