An absorbent structure having both osmotic and capillary absorbing capabilities. The absorbent structure comprises a capillary absorbent substrate, such as paper. The substrate has regions of relatively high and relatively low densities. The osmotic absorbent structure may include superabsorbents and is preferentially applied to the low density regions of the substrate. Preferably the low density regions are discrete, so that an essentially continuous high density network is present between the low density regions. This arrangement provides for better absorption of liquids without gel blocking. The absorbent structure is suitable for use in the cores of disposable absorbent articles.

L'invention concerne une structure absorbante capable d'absorber aussi bien par osmose que par capillarité. La structure absorbante comprend un substrat absorbant par capillarité, tel que le papier. Le substrat a des régions ayant une densité relative haute et d'autres régions ayant une densité relative basse. La structure absorbant par osmose peut comporter des superabsorbants et elle est, de préférence, appliquée aux régions à densité basse du substrat. De préférence, les régions à densité basse sont discrètes, de sorte qu'un réseau à densité haute essentiellement continu est présent entre les régions à densité basse. Cet agencement permet une meilleure absorption des liquides, sans blocages par suite de formation d'un gel. La structure absorbante convient comme noyau pour des articles absorbants à usage unique.
