Abstract
Tire cord fabric is processed by supporting a section of fabric and adjusting the warp cords to hang so that they are evenly distributed in a longitudinal direction. The fabric is then clamped in place and a dilute reactive polyurethane solution is sprayed to wet the cords on both sides of the fabric so that the coating on the cords is extremely thin and acts as a sizing material for the fabric to give it dimensional stability and preserve the interstices of the cords. The fabric is then heated to evaporate the solvent and cause the polyurethane mixture to be at least partially cured and to at least partially cover the cords of the fabric. The treated fabric may be used to reinforce a cast polyurethane tire.
