Absorbent structure

Abstract

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.

1 . An absorbent structure with a sequence of layers, comprising:
 at least one liquid absorbent 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 layer structure,   wherein at least the liquid storage layer and the liquid distribution layer at least respectively include an air laid material as a main component, preferably an air laid layer which includes cellulose fibers,   wherein a portion of the air laid material in the liquid distribution layer has smaller pores then a portion of the air laid material in the liquid distribution layer,   wherein the liquid storage layer includes super absorbent polymer, in particular as a key particles,   wherein the super absorbent polymer extends from the liquid storage layer into liquid distribution layer for generating a reverse suction effect for liquid which has entered through the liquid absorption layer and the liquid storage layer into the liquid distribution layer.
