ABSTRACT:
A process of bonding aromatic polyamide fibers to rubber compounds is disclosed, which comprises:
the first step of treating fibers with an aqueous mixture comprising a resorcinol/formalin resin and a latex of a polymer containing halogens in amounts of not less than 45% by weight based on the polymer;
the second step of treating the fibers with an aqueous adhesive composition comprising a resorcinol/formalin resin and a latex of an adhesive rubber which is compatible with the rubber in the rubber compound; and
the third step of placing the fibers in close contact with the rubber compound and vulcanizing the rubber together with the fibers.
A second process is further disclosed wherein in the second step, the fibers are treated with an adhesive solution comprising at least one activating agent selected from the group consisting of polyisocyanates and polyepoxy compounds in organic solvents.
