Abstract
An absorbent article includes at least one liquid-permeable layer material () and an absorbent structure (), the absorbent structure () having the ability to expand on wetting, which entails that the absorbent structure () displays a first volume in dry condition and a second volume in completely expanded wet condition, the second volume being greater than the first volume. The liquid-permeable layer material () encloses the absorbent structure () so that the absorbent structure () is prevented from reaching complete expansion during wetting.
