The present invention relates to a polyester yarn for a tire cord excellent in shape stability and improved in adhesion, and to a dip cord using the polyester yarn. The polyester yarn for tire cord has a strength of 6.0 g / d or more, ES (@ 6.8 kg) 8.0% or less, the strength of the dipped cord is 19.0 kg or more, the ES (@ 6.8 kg) index is 5.2% or less, the initial adhesive strength is 17.0 kg or more, and the heat resistant adhesive strength is 11.0 kg or more. The polyester yarn for a tire cord of the present invention and the dip cord using the polyester cord of the present invention have an effect of improving the initial adhesive force and the heat-resistant adhesive force by 10% or more as compared with the conventional dip cord, excellent in shape stability, There are advantages. |
