  • Publication number: 20200130432
    Abstract: 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 the tire 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.
