"CARPET PRODUCT WITH INTEGRAL BALANCING LAYER" Abstract of the Disclosure An improved carpet product includes a pile fabric layer and a stabilizing layer adhered to the back of the pile fabric layer to provide dimensional stability against concentrated stresses exerted against the upper surface of the carpet. A balancing layer disposed below the stabilizing layer has thermal response and moisture absorption characteristics selected for compatibility with the pile fabric layer. When the carpet product is exposed to temperature extremes or changes in ambient humidity, stresses exerted by the expansion or contraction of the pile fabric layer create a bending moment around the stabilizing layer. However, the balancing layer creates comparable stresses on the lower side of the stabilizing layer and exerts an equal-but-opposite bending moment which balances the moment exerted by the pile fabric layer. The resulting carpet product exhibits enhanced flatness and floor hugging characteristics when subjected to temperature extremes or changes in the ambient humidity.
