Abstract
Rubber-reinforcing polyamide fiber cords are disclosed which are each obtained by primarily twisting an aromatic polyamide filament yarn, doubling a plurality of thus primarily twisted yarns and finally twisting doubled yarns in a twisting direction opposite to that of the primary twist yarn to obtain a plied yarn, and applying a rubber adhesive to the thus obtained plied yarn. N and M satisfy the following relation: 1.05.ltoreq.M/N.ltoreq.1.6 in which N and M are the number of primary twists and the number of the twists in the cord, respectively.
