The present invention concerns a textured floor covering composite comprising a highly conformable fibrous outer layer 101 and an optional porous and resilient backing layer 102 that are continually, contiguously, or continuously attached to an activated adhesive layer 103 along a three-dimensional, undulating interface. The undulations correspond to depressed and elevat-ed areas on the surface of the composite. Such a composite can be fabricated if its precursor is subjected to heat and pressure for a finite length time, provided that the applied pressure is relatively low, preferably under about 200 psi. The textured composite can be used as a floor covering that advantageously resists warping and remains insensitive to variations in ambient temperature and humidity, including exposure to water.

La présente invention concerne un revêtement de sol texturé composite comprenant une couche extérieure fibreuse hautement adaptable 101 et une couche de dossier poreuse et élastique optionnelle 102 qui sont attachées de façon continuelle, contiguë ou continue à une couche d'adhésif active 103 le long d'une interface ondulante tridimensionnelle. Les ondulations correspondent à des régions creuses et saillantes sur la surface du composite. Un composite de ce type peut être fabriqué si son précurseur est soumis à une chaleur et une pression pendant une période de temps définie, pourvu que la pression appliquée soit relativement basse, de préférence inférieure à environ 200 psi. Le composite texturé peut être utilisé comme un revêtement de sol qui résiste avantageusement au gauchissement et qui reste insensible aux variations de la température et de l'humidité ambiantes, y compris à l'exposition à l'eau.
