An absorbent structure having both osmotic and capillary ab- sorbing capabilities. The substrate has a topography comprising two different elevations. The osmotic absorbent structure may include su- perabsorbents and is preferentially applied to the high elevation regions of the substrate. This arrangement provides for better acquisition of liquids without gel blocking. The absorbent structure is suitable for use in the cores of disposable absorbent articles.

Structure absorbante à capacités osmotiques et capillaires dont le substrat présente une topographie à deux niveaux. La partie absorbant par osmose qui peut comprendre des superabsorbants est de préférence localisée dans la région supérieure du substrat. Cette disposition permet un meilleur recueil des liquides en évitant les blocages par des gels. Ladite structure peut constituer le noyau d'articles absorbants à jeter.
