PROCESS FOR PRODUCING FIBER-RUBBER COMPOSITE

摘要

A process for producing a fiber-rubber composite comprising: a polyester fiber treated with (1) an adhesive composition (AR) consisting mainly of a latex (A) of a vinylpyridine-conjugated diene type copolymer containing a vinylpyridine unit in an amount of not less than 20 % by weight but not more than 70 % by weight and a resorcinol-formaldehyde resin and then with (2) an adhesive composition (BR) consisting mainly of a latex (B) of a nitrile group-containing highly saturated copolymer rubber having an iodine value of 120 or less obtained by emulsion polymerization or by emulsion polymerization followed by hydrogenation in the emulsion state and a resorcinol-formaldehyde resin, and a nitrile group-containing highly saturated copolymer rubber having an iodine value of 20 or less, which process comprises bonding said polyester fiber and said nitrile group-containing highly saturated copolymer rubber having an iodine value of 20 or less, by vulcanizing by a peroxide vulcanizing system.
