Abstract
Polyamide fiber cords for rubber reinforcement are produced by subjecting cords having a denier per filament of 1.5-10 to RFL adhesive solution having a swelling ratio in DMSO of 122-340% at an impregnated state in cord, embedding the thus treated cords in rubber and vulcanizing them, and have a cord strength in rubber of not less than 8.0 g/d. They provide excellent fatigue resistance under repetitive compressive strain without lowering strength in the dipping and vulcanization.
