Abstract

Non-slip floor covering and method of producing a non-slip floor covering. The non-slip floor covering includes a plurality of depressions that are regularly or randomly distributed over a floor covering surface such that the depressions provide a suction effect. The method includes directing pulsed laser beams onto a surface of the floor covering, forming micro-craters having suction effect with the directed pulsed laser beams, and distributing the formed micro-craters over the surface of the floor covering.
