Abstract: A method of producing a reinforced fabric including producing by a knitting or weaving process a ground fabric using ground yarns and incorporating into the ground fabric during the knitting or weaving process reinforcement yarns in a predetermined pattern to form predetermined areas of reinforcement, the reinforcement yarn being a stretch resistive yarn coated with a weldable material, and subsequently exposing the fabric to a weldable condition in order to cause said weldable material to weld to itself and to ground yarns with which it is in contact.
