An absorbent article such as a diaper or an incontinence protector, comprising at least one liquid storage region ( ) with high absorption capacity and at least one wicking layer ( ) which overlaps at least a substantial part of the liquid storage region and which has greater liquid dispersion ability than the storage region. The wicking layer ( ) is intended to disperse liquid collected locally in the article over the liquid storage region ( ). The aim of the invention is to improve liquid dispersion in absorbent articles. The invention is characterized in that liquid-impermeable portions ( ) are arranged at separate places in the article along sections of overlapping parts of the wicking layer ( ) and the liquid storage region ( ) in order to prevent the transfer of liquid over said parts from the wicking layer to the storage region. The liquid impermeable portions ( ) are placed in such a way that liquid from at least one initial accumulation place in connection with wetting of the article is first dispersed in the wicking layer ( ) along said portions separated from the liquid storage region ( ) and thereafter is dispersed further in the liquid storage region at a distance from said accumulation place.

Absorbent article with improved liquid dispersion

An absorbent article, such as a sanitary napkin, a panty liner or a female incontinence napkin, is intended to be carried in the crotch part of the wearer inside her underwear, has a generally elongate shape and includes two long sides, two short sides, two end-portions, a center portion located between the end-portions, a liquid-permeable casing sheet that is intended to lie proximal to the wearer's body in use, a liquid-impermeable casing sheet that is intended to lie distal form the wearer's body in use, and further includes between the layers, as seen in a direction from the liquid-permeable casing sheet towards the liquid-impermeable casing sheet, a drainage layer, an absorption layer, and a hump-forming element which forms together with the drainage layer and the absorption layer a hump that projects out from the plane of the napkin on that side of the napkin which is intended to lie proximal to the wearer in the use. In one embodiment, at least one cut is made through the drainage sheet and the absorption layer, and the hump-forming element is pushed up through these layers.
