Abstract:
The present invention relates to a drawn PET fiber which has good dimensional stability, thereby increases the high speed driving performance of a tire, a PET tire cord, their preparation methods, and a tire including the same. The drawn PET fiber may includes 90 mol % or more of PET and may be a fiber of which a creep rate is 5.5% or less when the drawn PET fiber is fixed under the initial load of 0.01 g/d and is kept for 24 hours under the load of 0.791 g/d and the temperature of 100° C. Furthermore, the PET tire cord may be a cord of which a creep rate is 4.0% or less when the PET tire cord is fixed under the initial load of 0.01 g/d and is kept for 24 hours under the load of 0.791 g/d and the temperature of 100° C.
