This can be a vapor deposition with different media, the use of sol-gel or a plasma treatment.

Zur Erhöhung der Festigkeit des erfindungsgemäßen Wirkstoffkörpers 1 können die der Oberfläche abgewandten Faserenden mittels eines entsprechenden Klebstoffs untereinander verklebt werden. Dabei ist es wichtig, dass möglichst wenig Klebstoff eingesetzt wird, also eine optimale Verteilung vorliegt und dieser nicht oder nur sehr gering die Oberfläche des Saugmaterials benetzt. Dadurch und durch seine eigene Elastizität bleibt vorteilhafterweise die Verformbarkeit des Materials optimal erhalten. Beispielsweise sind zur Verklebung Polyethylenfasern oder -vliese sowie ein entsprechendes Pulvermaterial vorgesehen.To increase the strength of the active ingredient body according to the invention 1 The fiber ends facing away from the surface can be glued together by means of a corresponding adhesive.

The movement phase of the fibers in the knitting process as well as the leadership the flow of air and the arrangement of the entry nozzles determine the optimal Wetting and swirling of the fiber ends.

Erfindungsgemäß besteht auch die Möglichkeit, dass die Oberfläche und der Zwischenraum zwischen oberer und unterer Deckschicht 15 und 25 durch ein Wasserstrahlverfahren verformt werden. Hierbei kann eine Schablone Anwendung finden, wobei eine unterschiedliche Beaufschlagung der Wasserstrahlen auf der Deckschicht aus vermaschten Fasern Anwendung finden kann. Über die Schablone erfolgt eine zusätzliche Beschichtung auf der Deckschicht 15 bzw. 25.According to the invention there is also the possibility that the surface and the space between the upper and lower cover layer 15 and 25 be deformed by a water jet method. In this case, a template can be used, wherein a different application of the water jets on the cover layer of intermeshed fibers can be applied. Over the stencil an additional coating on the cover layer takes place 15 respectively. 25 ,
