ABSTRACT:
In a V-ribbed belt, cords made of polyester fibers are embedded into an adhesion rubber layer made of chlorosulfonated polyethylene rubber whose polymer ingredient is so compounded that the content of chlorine is 15 to 35 wt. % and the content of sulfur is 0.5 to 2.5 wt. %, thereby reinforcing the adhesion rubber layer. The cords are treated with two kinds of adhesives. A first adhesive for first treatment is an adhesive having at least one of an isocynate compound and an epoxy compound. A second adhesive for second treatment is an adhesive formed of a mixture having at least resorcineformaldehyde resin and 2,3-dichlorobutadiefie-contained polymer. A surfactant is added to the second adhesive so that the cords and the adhesion rubber layer are Securely adhered, thereby enhancing dynamic adhesive strength of the V-ribbed belt.
