PURPOSE:To enable the bonding of a fiber and a hydrogenated nitrile rubber compound useful for tire, etc., in high adhesivity and peel strength by contacting and vulcanizing a specific hydrogenated nitrile rubber compound and a fiber material treated under specific condition. CONSTITUTION:A hydrogenated nitrile rubber compound having a hydrogenation degree of 80-99% and containing preferably 5-60 pts.wt. (based on 100 pts.wt. of the rubber) of an ethylenic unsaturated carboxylic acid metal salt (e.g. zinc acrylate) and preferably 0.2-10 pts.wt. of an organic peroxide (e.g. dicumyl peroxide) is bonded to a fiber material such as aramid fiber by treating the fiber material with a solution containing an epoxy-modified polyol compound and a polyisocyanate compound such as tetramethylene diisocyanate, treating with a mixture of resorcinol, formalin and a rubber latex, contacting with the above rubber compound and vulcanizing the product. |
