Abstract:
Disclosed are a hybrid cord produced by plying and twisting high modulus yarns and polyamide monofilaments, and a tire including the same. More specifically, disclosed is a method of producing a hybrid cord having a clear core-covering structure including a core comprising a polyamide monofilament and a covering spirally twisted around the core and comprising a high modulus yarn. The hybrid cord can clearly control the modulus ratio in each area, improving production efficiency of the cord and processability of the tire and reducing deviations of uniformity and driving performance. In addition, the tire using the hybrid cord reduces tire deformation during driving, thus satisfying both driving performance and comfort.
