Verfahren zur Mikrostrukturierung von Oberflaechen oder polymeren Substraten mit Laserstrahlung

The description relates to a process for the microstructuring of surfaces, in particular surfaces of textile products, using laser radiation which is absorbed by the surface. The process is characterized by the fact that the surface is applied with a spatial power-density-modulated laser radiation. During the microstructuring of the surfaces of textile products, the surface of filaments or the surface of fibres, yarns, fabrics or textiles manufactured from said filaments are applied with the spatial power-density-modulated laser radiation. Preferably, the spatial power-density modulation is formed as the interference field of two or more laser beams capable of producing interference.
