Mechanical embossing texture differentiation between chemically foamed areas and non-foamed areas

摘要

Disclosed is a method of manufacturing a mechanically and chemically embossed surface covering having selectively textured surfaces. The method includes forming a web (19) coated with a wear layer (18). The coated web is heated to a temperature at which the wear layer is cured, the foam layer (14) expands, and the pattern is chemically embossed to form a surface covering having foamed regions and nonfoamed regions. The temperature gradient of the surface covering is adjusted such that there is a temperature gradient difference between the foamed and nonfoamed regions. A surface texture is then mechanically embossed into the wear layer (18) and selectively set onto the wear layer substantially overlying the non-foamed regions.
