摘要:
The present invention relates to an absorbent structure with a sequence of layers comprising at least one liquid absorption layer a subsequent liquid storage layer with superabsorbent polymer SAP preferably SAP particles and/or SAP fibres 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 airlaid material preferably an airlaid ply comprising cellulose fibres as main constituent an area of the airlaid material in the liquid distribution layer being more narrowly pored than an area of the airlaid material in the liquid storage layer and wherein the liquid storage layer has superabsorbent 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 liquid that has passed through the liquid absorption layer and liquid storage layer into the liquid distribution layer.
