US 2017/0030014 A1 · Coated non-woven fabrics from inorganic fibers and functional, decorative layers for floor coverings, ceiling coverings and wall coverings manufactured therefrom

Abstract

The present invention relates to a non-woven fabric made of inorganic fibers, which has a coating of at least two layers on one of both surfaces, wherein (i) the non-woven fabric made of inorganic fibers has a thickness of at least 0.2 mm, (ii) the first layer of the coating comprises particles, whose particle size is between 50 and 100 μm, (iii) the second layer of the coating, which is applied onto the first layer, comprises particles, wherein more than 90% of the particles have a particle size of less than 20 μm. The non-woven fabric made of inorganic fibers according to the invention, in particular glass non-woven fabrics, are in particular suitable for producing decorative coatings for floor coverings, ceiling coverings and wall coverings.
