Code and a pneumatic tire using the same for carcass or belt layer reinforcement of a pneumatic tire

摘要

PPROBLEM TO BE SOLVED: To provide a cord for reinforcing rubber articles, which is hardly magnetized in a process for producing the rubber articles, during the employment of a tire, and the like, and little generates a magnetic field, and to provide a pneumatic tire using the same. PSOLUTION: The cord for reinforcing the rubber articles, composed of non-magnetic materials, includes at least one non-magnetic metal filament and at least one organic fiber filament. The cord for reinforcing the rubber articles, has an M+N layer twist structure, wherein the M core filaments are composed of preferably organic fiber filaments, and the N sheath filaments are composed of preferably non-magnetic metal filaments, or the M core filaments are composed of preferably non-magnetic filaments, and the N sheath filaments are composed of preferably organic filaments. The pneumatic tire uses the cords for reinforcing the rubber articles for one or both of carcasses and belts. PCOPYRIGHT: (C)2010,JPO&INPIT
