The present invention relates to the use of an absorbent expanding material (46) in an absorbent article, such as a sanitary napkin (20) in order to concentrate the absorbed liquid in the central region of the absorbent article. In particular the present invention relates to the use of an absorbent expanding material (46) which upon absorption expands more than the absorbed volume of liquid required in order to provide additional void volume. In addition, the present invention relates to absorbent articles such as baby diapers, adult incontinence products or sanitary articles in which the material of the absorbent core has a better liquid transport capability into the thickness of the article than within the plane of the article.
L'invention concerne l'utilisation d'un matériau absorbant (46) qui se dilate dans un article absorbant, tel qu'une serviette hygiénique (20), afin de concentrer le liquide absorbé dans la zone centrale dudit article. Elle concerne notamment l'utilisation d'un matériau absorbant (46) qui se dilate et qui, après absorption, se dilate davantage que ne l'exige le volume de liquide absorbé, de façon à offrir un volume vide supplémentaire. Elle concerne enfin des articles absorbants tels que couches pour bébés, produits d'incontinence pour adultes et articles hygiéniques, dont le matériau de l'âme absorbante a des capacités de transport des liquides plus importantes dans l'épaisseur de l'article que dans son plan.
