Abstract

Feinstporieren von Kunststoffolien und anderen Materialien mittels Hochspannungsimpulsen findet ihre Grenze, wenn die materialspezifische Dielektrizitätskonstante oder die Dicke des Materials zu hoch ist. Fine poring of plastic films and others Materials are found using high-voltage pulses Limit if the material specific dielectric constant or the thickness of the material is too high.

Das erfindungsgemäße Verfahren sieht daher vor, die elektrisch nicht porierbaren Materialen (Kunststoffolie 2) in einem Nadelungsprozeß mit einer Vielzahl von Durchstichen (3) zu versehen, anschließend die Oberfläche der Folie (2) durch eine dünne, elektrisch porierbare Auflage oder Schicht (4) wieder zu verschließen, um dann diese Schicht (4) in einem Feintporierprozeß mittels Hochspannungsimpulsen im Bereich der Durchstiche (3) mit wasserdampfdurchlässigen, aber wasserdichten feinsten Poren (5) zu versehen. The method according to the invention therefore provides that electrically non-porous materials (plastic film 2) in a needling process with a large number of punctures (3), then the surface of the film (2) through a thin, electrically porous pad or layer (4) to close again, then this layer (4) in one Fine poring process using high voltage pulses in the Area of the punctures (3) with water vapor permeable, but to provide watertight finest pores (5).
