Hybrid cord and rubber product

摘要

There is provided a hybrid cord having excellent dimensional stability and flexing resistance for use in a reinforcement of rubber, and a rubber product reinforced with the hybrid cord. The hybrid cord 1 has glass fiber strands 2 disposed at its center, and aramid fiber strands 3 disposed therearound. Glass fiber filaments applied with RFL treatment are bound to form the strands. A plurality of the strands are primarily twisted at a twisting rate of 1 to 10 turns/25 mm. Aramid fiber filaments applied with RFL treatment are bound to form the strands. A plurality of the strands are primarily twisted at a twisting rate of 1 to 10 turns/25 mm. The glass fiber strands 2 primarily twisted are disposed at a center, and the aramid fiber strands 3 are properly twisted in an opposite direction to the primary twist. The cord is overcoated to form a rubber coat.
