Abstract:
1. An absorbent article comprising a liquid-permeable surface layer and a liquid-impermeable surface layer and an absorption body arranged between the surface layers, the absorption body comprising a liquid-permeable material layer and an absorbent structure, the absorbent structure having the ability to expand on wetting and having a first volume in a dry condition and a second volume in a completely expanded wet condition, the second volume being greater than the first volume, wherein the liquid-permeable material layer constitutes a volume-limiting device for the absorbent structure so that the absorbent structure is prevented from reaching the completely expanded wet condition on wetting in an excess of 0.9% NaCl solution for 5 minutes and so that the absorbent structure after wetting in an excess of 0.9% NaCl solution for 5 minutes has a greater stiffness than in the dry condition and thus forms a forming element in the absorbent article, wherein the absorbent structure expands to a mean value of 70% or less of the completely expanded wet condition on wetting in an excess of 0.9% NaCl solution for 5 minutes, based on g/g increase.
