Abstract:
A method of manufacturing a mechanically and chemically embossed surface covering comprising:a) forming a chemically embossed surface covering comprising a wear layer overlying a chemically embossed foam layer, said foam layer having a foamed region and a non-foamed region, said chemically embossed surface covering having a back-side opposite the wear layer; b) adjusting the temperature gradient of the surface covering such that there is a temperature gradient difference between the foamed region and the non-foamed region wherein the surface temperature of the back-side of the chemically embossed surface covering is higher than the surface temperature of the wear layer; and c) thereafter, mechanically embossing the wear layer of the surface covering whereby a surface texture is set predominantly into the wear layer substantially overlying the non-foamed region.
