PURPOSE: A method of manufacturing hybrid dip cord and a hybrid dip cord manufactured by the same are provided to give appropriate twists to polyethyleneterephthalate yarn and polyketone yarn, and to manufacture a hybrid dip cord for a vehicle radial pneumatic tire. CONSTITUTION: The manufacture of hybrid dip cord has following steps. A pre twisted yarn is manufactured by applying a S direction of 30 - 90 TPM to one layer of polyethyleneterephthalate yarn. A post twisted yarn is manufactured by applying a Z direction of 300 - 500 TPM to one layer of polyethyleneterephthalate pre twisted yarn and one layer of untwisted polyketone yarn, respectively. The raw cord is manufactured by plaiting the post twisted yarn into two layers and applying a S direction of 300 - 500 TPM. The raw cord is processed by being dipped into a dipping liquid.
