To provide a rubber reinforcement fiber cord which contains a raw material derived from renewable resource, is easily molded into a tire and the like, maintains initial elongation, and on the other hand, exhibits high elastic modulus specific to a high elastic modulus fiber in subsequent elongation regions.SOLUTION: A rubber reinforcement cord, in which a surface of an organic fiber cord is coated with a rubber adhesive containing at least one layer of latex, is characterized in that the organic fiber cord is a twisted yarn cord in which a nylon fiber containing a raw material derived from renewable resource and an aramid fiber are twisted.SELECTED DRAWING: None
【課題】再生可能資源に由来する原材料を含み、タイヤ等に成形加工し易く、初期伸びを維持しつつ、一方で以降の伸度領域では高弾性率繊維特有の高弾性率を発揮する、ゴム補強用繊維コードを提供する。【解決手段】有機繊維コードの表面を、少なくとも1層のラテックスを含むゴム用接着剤で被覆してなるゴム補強用コードであって、前記有機繊維コードが、再生可能資源に由来する原材料を含むナイロン繊維と、アラミド繊維を撚り合わせた撚糸コードであることを特徴とするゴム補強用コード。【選択図】なし
