Abstract
A reinforcement fibrous cord having excellent adhesive strength produced by impregnating a meshed cord fabric formed from warp yarns for reinforcement cords and weft yarns having a softening temperature or a melting temperature lower than any of the softening temperature, the melting temperature and the thermal decomposition-initiating temperature of the warp yarns, with adhesive agent, and heat-treating the fabric at the temperature equal to or higher than the softening or melting temperature of the weft yarn and lower than any of the softening temperature, the melting temperature and the thermal decomposition-initiating temperature of the warp yarns so that the weft yarns are self-broken while being fuse-adhered to the adhesive agent-impregnated warp yarns whereby projections caused by the broken residues of the weft yarns are formed on the warp yarns.
