Abstract
An absorbent article includes at least one liquid-permeable layer material (105) and an absorbent structure (106), the absorbent structure (106) having the ability to expand on wetting, which entails that the absorbent structure (106) 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 (105) encloses the absorbent structure (106) so that the absorbent structure (106) is prevented from reaching complete expansion during wetting.
