To provide a composite fiber cord for reinforcing rubber, which simultaneously satisfies the moldability of a rubber composition owing to elongation upon molding, required during molding processing of a rubber product, and stiffness desired in the cord when a rubber molded article is finally used.SOLUTION: A composite fiber cord for reinforcing rubber is a composite fiber cord which comprises a fiber bundle A comprising high-elastic-modulus fibers and a fiber bundle B comprising low-elastic-modulus fibers. The fiber bundle A is a plied fiber bundle which comprises two or more fiber bundles, and in which first twisting and second twisting are performed in opposite directions. The fiber bundle A and the fiber bundle B are both further subjected to second twisting in a direction opposite to the second twisting direction of the fiber bundle A. The composite fiber cord for reinforcing rubber contains a rubber component. Further, it is preferable that: the fiber bundle B is preliminarily subjected, before the second twisting, to first twisting in an opposite direction; and the high-elastic-modulus fiber is one fiber selected from the group of a glass fiber, aromatic polyamide fiber, carbon fiber, polyparaphenylene benzoxazole fiber, and aromatic polyester fiber.SELECTED DRAWING: None

    【課題】ゴム製品の成型加工時に求められる成型時の伸張によるゴム組成物成形性と、最終的にゴム成形物を使用する際にコードに期待される剛性とを同時に満たすゴム補強用の複合繊維コードの提供。【解決手段】高弾性率繊維からなる繊維束Aと、低弾性率繊維からなる繊維束Bから構成される複合繊維コードであって、繊維束Aが2本以上の繊維束からなる下撚りと上撚りが逆方向の諸撚り繊維束であり、繊維束Aと繊維束Bとが共に、繊維束Aの上撚り方向と逆方向にさらに上撚りされており、ゴム成分を含有するゴム補強用の複合繊維コード。さらには、繊維束Bが上撚り前に、あらかじめ逆方向に下撚りされたものであることや、高弾性率繊維が、ガラス繊維、芳香族ポリアミド繊維、カーボン繊維、ポリパラフェニレンベンゾオキザール繊維、芳香族ポリエステル繊維の群から選ばれたいずれか一つの繊維であることが好ましい。【選択図】なし
