Abstract:
Disclosed are a hybrid tire cord, which can be easily manufactured and has more uniform physical properties, and improved strength and fatigue resistance, and a method for manufacturing the same. The hybrid tire cord includes a nylon primarily twisted yarn and an aramid primarily twisted yarn, wherein the nylon primarily twisted yarn and the aramid primarily twisted yarn are secondarily twisted together, and after untwisting of the secondary twisting of the hybrid tire cord having a predetermined length, a length of the aramid primarily twisted yarn is 1.005 to 1.025 times a length of the nylon primarily twisted yarn.
