Preparing molded article, comprises exposing a foam layer in a first region at 0-200[deg] C and a pressure of 0-150 bar; compressing the foam layer in pressure effect to 12.5-100% of its original volume; exposing a foam layer in a second region at 100-200[deg] C and a pressure of 50-150 bar; compressing the foam layer in pressure effect to 0-12.5% of its original volume, where the foam layer in the first area and the second area contains polyurethane. Preparing molded article, comprises exposing a foam layer in a first region at 0-200[deg] C and a pressure of 0-150 bar; compressing the foam layer in pressure effect to 12.5-100% of its original volume; exposing a foam layer in a second region at 100-200[deg] C and a pressure of 50-150 bar; compressing the foam layer in pressure effect to 0-12.5% of its original volume, where the foam layer: in the first area and the second area contains polyurethane and is obtained by foaming a composition comprising an aqueous, anionic hydrophilic polyurethane dispersion and drying. An independent claim is included for the molded article obtained by the above method, comprising a foamed region (10) and compressed region (20), where the compressed region is obtained by compressing the foam layer. |
