Abstract
Elastomer-coated fabric products having predetermined potential extension in the fabric's machine direction and processes for producing the same. The fabric product of the invention preferably includes an elastomer-coated warp-knit, weft-insert fabric whereby the warp knit yarns provide a first potential elongation (as by selection of the type and/or denier of yarns employed). The fabric is compressed in the machine direction (as by overfeeding the fabric to a tenter frame during production) so as to provide a second potential elongation, and is maintained in its compressed state by virtue of the elastomer coating thereon. The first and second elongation potentials thus collectively establish the total potential elongation for the fabric in the machine direction. The cross-machine yarns, however, are chosen for their inextensible properties so that the fabric product of this invention will provide lateral support to end use products employing the same as a reinforcing medium, such as tires, power transmission belts, conveyor belts, and the like.
