摘要：
The present invention relates to a drawn PET fiber which has good dimensional stability and can be applied to a cap ply cord for a pneumatic 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 the shrinkage rate under the conditions of the load of 226g/1000d and the temperature of 180 °C is 25% or more of the shrinkage rate under the conditions of the load of 20g/1000d and the same temperature. Furthermore, the PET tire cord may be a cord of which the shrinkage behavior index under the conditions of the load of 0.0565g/d and the temperature of 180 'C is 0.1(g/d)/% or more, or a cord of which the shrinkage rate under the conditions of the load of 226g/cord and the temperature of 180 °C is 50% or more of the shrinkage rate under the conditions of the load of 20g/cord and the same temperature.
