Abstract
The present invention is directed to a method wherein fibers are treated with a first, second, and third treatment solution. The third treatment solution includes a chlorinated rubber and a rubber-containing composition having acrylonitrile-butadiene rubber or hydrogenated acrylonitrile-butadiene rubber. The treated fibers are positioned contiguous, and adhered, to an unvulcanized hydrogenated acrylonitrile-butadiene rubber composition which is then vulcanized. The resulting rubber-fiber composite exhibits improved adhesion between the hydrogenated acrylonitrile-butadiene rubber composition and the fibers. Adhesion is maintained in a hot environment even if subjected to what would conventionally be considered conditions that would result in thermal deterioration under high temperature. Thus, the rubber-fiber composite exhibits enhanced durability under the severe service conditions experienced by rubber-fiber composites.
