Abstract
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.
