The present disclosure relates to a tire cord fabric, a method of manufacturing the same, a sheet including the same, and a tire including the sheet, and the tire cord fabric includes a plurality of tire cords which are arranged in parallel to each other, a weft yarn which weaves the tire cords to conduct a weaving operation, and a conductive fiber which comes into contact with the surface of thetire cord and is extended in a longitudinal direction of the tire cord. The tire cord fabric can effectively discharge static electricity aggregated in a tire by mixing a tire cord with a conductive fiber, thereby weaving a mixture of the tire cord and the conductive fiber. Particularly, the tire cord fabric can secure an effective conductive passage since the conductive fiber is extended in a radial direction from bead parts to a tread part as in a carcass cord.Therefore, the tire cord fabric can simultaneously accomplish solving of a static electricity problem and obtaining of a fuel efficiency improving effect through low rolling resistance as a result by decreasing a demand associated with electrical conductivity of a rubber composition for sidewall and a rubber composition for topping, thereby enabling a rubber composition having a low loss modulus (E'') for improving rolling resistance to be applied.
本发明涉及一种轮胎帘布、其制备方法、包括其的片材及包括该片材的轮胎,上述轮胎帘布包括:多个轮胎帘线(tire cords),彼此平行排列;纬纱,用上述轮胎帘线编织来织造;及导电纤维,与上述轮胎帘线表面接触,沿上述轮胎帘线的长度方向延伸。在通过将导电纤维混入轮胎帘线中来纺织上述轮胎帘布时,可以有效地释放聚集在轮胎上的静电,尤其,如同胎体帘线,上述导电纤维在径向方向上从胎圈部分延伸到胎面部分,从而可以确保有效的导电通道。由此,由于对胎侧用橡胶组合物和贴合用橡胶组合物的导电性的要求降低,因此可以应用具有用于改善滚动阻力的低损耗模量(Loss Modulus,E″)的橡胶组合物,结果,能够解决静电问题且通过低滚动阻力实现油耗改善效果。
