METHOD OF PRODUCING A COMPOSITE WITH AN ABSORBENT LAYER
The present invention relates to a multilayer product having at least one first layer, an absorbent intermediate layer and a second layer, whereby at least the first layer contains at least one first material and one second material. The first layer and/or the second layer is at least partially liquid permeable. The first material has a higher melting point than the second material, with the second material creating a bond to the second layer.
1 . A method of producing a multilayer product having at least one first layer, an absorbent intermediate layer and a second layer, whereby at least the first layer has at least one first material and one second material, and the first layer and/or the second layer is at least partially liquid permeable, wherein a first material is used which has a higher melting point than the second material; the second material is heated at least approximately to its melting point, and the first layer and the second layer are bonded by means of the heated second material, and wherein the intermediate layer comprises a powder which is immobilized by the second material.
2 . The method according to claim 1 , wherein a powder is applied to the second material to form the absorbent intermediate layer at least in part before the second material is heated, whereby the powder is glued at least partially to the second material.
3 . The method according to claim 1 wherein the second material seals the intermediate layer at the sides.
4 . The method according to claim 1 , wherein the multilayer product is punched out of a continuously supplied sheet.
5 . The method according to claim 4 , wherein multilayer products are punched out, their contours being arranged with an offset relative to one another.
