Abstract
A process for producing a tubular rubber product such as a rubber hose and a rubber coupling in which a polyamide resin and/or polyester resin layer is formed to the main body of a tubular rubber product. The resin layer is formed either by coating an organic solvent-soluble nylon to the surface of the main body of the tubular rubber product applied with the surface treatment of a halogenoid compound, or by polyamide resin or by polyester resin film having a softening point in the vulcanization temperature region and treated with an adhesive mainly comprising a resorcine-formaldehyde resin and a rubber latex or treated with an adhesive rubber mainly comprising a resorcine, a formaldehyde-forming substance and a vinylpyridine-butadiene-styrene copolymer rubber and then bonding under vulcanization onto the main body of the non-vulcanized tubular rubber product.
