HYBRID CORD AND REINFORCED RUBBER ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a hybrid cord which is useful as a cord for reinforcing rubber and has excellent dimensional strength and excellent bending performance, and to provide a reinforced rubber article reinforced with the hybrid cord. SOLUTION: This hybrid cord 1 is prepared by disposing glass fiber strands 2 at the center and disposing aramid fiber strands 3 around the glass fiber strands 2. Preferably, the hybrid cord is prepared by collecting glass fiber filaments to form strands and then primarily twisting the prescribed number of the strands at a twisting rate of 1.0 to 10 twists/25 mm. The prescribed number of RFL-treated aramid fiber filaments are also collected and primarily twisted at a twisting rate of 1.0 to 10 twists/25 mm.
