(57) [Summary] [Problem] It has good adhesion to halogenated butyl rubber, A method for producing a fiber for reinforcing rubber with less trouble in a hose production process is provided. SOLUTION: A polyester fiber or an aramid fiber previously treated with a treating agent containing a polyepoxide compound, a resorcinol-formaldehyde initial condensate (A), vinylpyridine 13 to 20% by weight, styrene 25 to 45% by weight and butadiene 40 to 40%. A rubber characterized in that an adhesive agent containing 60% by weight of vinylpyridine / styrene / butadiene terpolymer latex (B) and parachlorophenol / resorcin / formaldehyde cocondensate (C) is applied and heat treated. A method for producing a reinforcing fiber. |
