Method of manufacturing liquid flow guiding structures to porous substrates

    Research output: PatentPatent


    The invention relates to a method for manufacturing liquid- guiding structural layers by flexo or gravure printing on a substrate sheet, using a printing solution, which alters the properties of the substrate sheet in such a way that liquid flow is prevented in the area of the structural layers. The penetrability of the printing layer into the substrate sheet can be regulated by the printing-cylinder pressure and the composition of the printing solution. In the method it is possible to use printing solutions consisting of economical polymers and a solvent. In terms of printing technology, the invention is compatible with existing printing machines and is thus highly suitable for mass production.
