ARAMID-POLYAMIDE 66 HYBRID CORD AND RADIAL TIRE WITH IMPROVED FUEL EFFICIENCY COMPRISING SAME

摘要

The present invention relates to an aramid-polyamide 66 hybrid cord that is obtained by doubling and twisting an aramid code of the low fineness of 200-600 denier and the polyamide 66 code of the low fineness of 200-500 denier, and an environmentally friendly radial tire comprising the same. The hybrid cord of the present invention maintains the initial modulus, which has a major influence on the noise and ride comfort at the level of the existing polyamide cord, and maintains the high modulus under the high load bringing out the properties of the aramid cord, and thus, the radial tire applying the hybrid cord of the present invention has an advantage of improving the high speed driving properties, the control stability, and the mileage performance.;COPYRIGHT KIPO 2014
