  • Absorbent article with improved liquid dispersion
    Patent number: 6835192
    Abstract: An absorbent article such as a diaper or an incontinence protector, comprising at least one liquid storage region (2, 3) with high absorption capacity and at least one wicking layer (4) 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 (4) is intended to disperse liquid collected locally in the article over the liquid storage region (2, 3). The aim of the invention is to improve liquid dispersion in absorbent articles. The invention is characterized in that liquid-impermeable portions (5, 6) are arranged at separate places in the article along sections of overlapping parts of the wicking layer (4) and the liquid storage region (2, 3) in order to prevent the transfer of liquid over said parts from the wicking layer to the storage region.
