ABSTRACT:
An aesthetically pleasing texture is imparted to wet-laid fibrous mats by distributing a layer of solid expanded particles of synthetic thermoplastic resinous foamed material on the upper surface of the mat. The particles are then pressed into the wet lap to embed the particles in the fibrous material and the wet lap is subsequently heated to reduce the volume of the particles and leave depressions in the surface which result in a unique random surface texture.
