摘要
采用92.6 dtex/72 f聚对苯二甲酸丙二醇酯(PTT)POY为原料,在AFK-1000型加弹机上生产83dtex/72 f PTT DTY,讨论了DTY的生产工艺。结果表明:选择加工速度450 m/min,第一热箱温度150℃,关闭第二热箱,拉伸倍数1 20,D/Y比1 50～1.51,网络压力0.04 MPa,摩擦盘为聚氨酯摩擦盘,生产的PTTDTY后加工性能好。
The polytrimethylene terephthalate （PTr） DTY of 83 dtex/72 f was produced from 92.6 dtex/72 f PTr POY on an AFK-1000 texturing machine. The production process of PTT DTY was discussed. The results showed that the PTT DTY with fairly good after-processing performance can be obtained under the conditions as followed ： processing speed 450 m/min, the first heater temperature 150℃, the shut-down second heater, draw ratio 1.20, D/Yratio 1.50 - 1.51, interlace pressure 0.04 MPa, polyurethane friction disc.
