The present invention is directed to multiple-layer composites suitable for use as floor-coverings in the form of cut tiles or broadloom sheets, providing a durable and highly stable structure that can lay flat and remain flat with variations in temperature and humidity and provide a durable and yet soft textile face. The composite comprises a laterally-compressible fabric face bonded with an adhesive layer to a highly conformable stress-absorbing cushioning layer. The face fabric comprises closely packed looped yarns reciprocating between the top and the bottom of the fabric, protruding into the adhesive layer and emerging from the adhesive layer to the surface forming micro-spring structures. The weight, properties, density and level of penetration of adhesive are controlled to maintain lateral compressibility for the entire composite and avoid warping.
A floorcovering composite comprising a fabric face layer joined to a cushioning layer with adhesive partially penetrating both layers forming an adhesive composite layer (18), wherein the surfaces of the face fabric are formed with yarns reciprocating from one surface to the other surface forming peak loops and trough loops, and wherein the yarns forming peak loops descend from the peaks into adhesive within a lateral distance X,
The floorcovering composite of claim herein the barrier layer comprises a gas permeable, liquid impermeable material.
