tire fabric

A loose fabric woven to facilitate large-scale dipping, treating, and calendering of tire cords. Usually, 15 to 35 tire cords per inch of warp are woven into a tire fabric by 2 to 5 light filling yarns per inch. In these fabrics, the strength is in the warp and the filling only holds cords in position for processing. The filling yarns are normally broken during tire molding. The warp cords are polyester, rayon, nylon, aramid, glass, or steel and range in strength from 30 pounds to over 100 pounds per cord. A 60-inch fabric would normally have a warp strength of about 7,000 pounds. Such fabrics are used for tire carcasses and tire belts. More conventional square woven fabrics are used in certain parts of a tire such as the bead, chafer, and wrapping.
