Application and Discussion of PET High Shrinkage FDY
Hong Cheng-ping · Synthetic Fiber in China · 2005
The process of PET high shrinkage FDY by one step of spin-drawing was introduced. The influence of key parameters on fiber shrinkage was described. The top quality of high shrinkage fiber was produced at the spinning temperature 280~288 ℃, spinning speed 3900~4500 m/min, velocity of quench air 0.3~0.5 m/s, take-up overfeed 0.7 %~1.4 % and suitable drawing temperature and thermal setting temperature.
