| Abstract: | Using conventional polyester chip as the raw material, the high shrinkage PET FDY was prepared by spinning drawing heat setting one step process. The adjustment of the temperature and velocity of heat rollers played an important role in the preparation of PET FDY with boiling water shrinkage higher than 50%. The shrinking mechanism and the process conditions in connection with hot shrinkage were discussed in detail. The experimental results showed that the obtained high shrinkage PET FDY had lower crystallinity and higher orientation. |
