RAW-EDGE V-BELT

A cord (20) is embedded in a V-belt body (10) of a raw edge V-belt (B) for transmission. The cord (20) is made of a plied yarn obtained by first twisting, in one direction, each of a plurality of filament bundles, each being made of polyester fibers of 2000 dtex or more to 3000 dtex or less, to make...

Zusammenfassung:A cord (20) is embedded in a V-belt body (10) of a raw edge V-belt (B) for transmission. The cord (20) is made of a plied yarn obtained by first twisting, in one direction, each of a plurality of filament bundles, each being made of polyester fibers of 2000 dtex or more to 3000 dtex or less, to make a plurality of first-twist yarns, paralleling the plurality of first-twist yarns, and second twisting the plurality of first-twist yarns in a direction opposite to the first twisting. A shrinkage force per dtex of the polyester fibers forming the cord (20), generated in a belt length of 300 mm when the raw edge V-belt (B) is held in a temperature atmosphere of 120°C for one hour is 0.0015 N or more.
