(57) [Abstract] [Purpose] To provide a rubber / cord composite in which the properties of organic fibers such as polyester fibers are retained and the adhesion between rubber and polyester fibers is improved. [Structure] An organic fiber such as a polyester fiber is treated with a first epoxy resin, an SBR latex having a specific styrene / butadiene monomer ratio and a specific heat-reactive water-soluble polyurethane resin, and then resorcinol. A method for producing a rubber / cord composite, which is treated with a second treatment liquid composed of a formalin condensate and a rubber latex and then integrally vulcanized with unvulcanized rubber. |
