Title: PRODUCTION METHOD FOR RUBBER-REINFORCING CORD, RUBBER-REINFORCING CORD, AND RUBBER PRODUCT
Abstract:
A method for producing a rubber-reinforcing cord that is for reinforcing a rubber product. The method includes: a step for mixing a phenolic aromatic compound-formaldehyde resin and a chlorosulfonated polyethylene rubber latex that has a pH of more than 4.0 but less than 7.0 to prepare a treating agent that contains the phenolic aromatic compound-formaldehyde resin and the chlorosulfonated polyethylene rubber latex; and a step for applying the treating agent to at least one portion of the surface of rubber-reinforcing fibers and drying to obtain a rubber-reinforcing cord in which a coating film has been formed on at least one portion of the surface of the rubber-reinforcing fibers. The chlorine content of the coating film is 1–30 mass%.
