摘要:
The present invention relates to an absorbent structure with a sequence of two layers comprising at least one liquid absorption layer, a subsequent liquid storage layer with super absorbent polymer SAP, preferably SAP particles and/or SAP fibers and a subsequent liquid distribution layer, wherein the layers are connected and form a sheet structure, wherein at least the liquid storage layer and the liquid distribution layer each at least have an air laid material, preferably an air laid ply comprising cellulose fibers as main constituent, an area of the air laid material in the liquid distribution layer being more narrowly pored than an area of the air laid material in the liquid storage layer, and wherein the liquid storage layer has super absorbent polymer, in particular SAP particles, extending from the liquid storage layer into the liquid distribution layer in order to generate a return suction effect for the liquid that has passed through the liquid absorbent layer and liquid storage layer into the liquid distribution layer.
