An absorbent structure in an absorbent article, such as a sanitary napkin, tampon, panty protector, incontinence guard, diaper and the like, which is produced by including in the absorbent structure a polymeric foam having cells which were initially essentially closed and which has been worked so as to open said cells, and the structure has obtained liquid take up properties. The foam has a density between 0.01-0.5 g/cm3. The material has porperties which are effective in achieving the function for which the product is intended. The foam may be formed as a sheet and the sheet can be made very thin and light, with a surface weight of between 10-500 g/m2, and the article will therefore exhibit good comfort properties to the wearer and requires only a small amount of material for its manufacture.
Structure absorbante utilisée dans un article absorbant, tel qu'une serviette hygiénique, un tampon, un protège-slip, un élément de protection contre l'incontinence, une couche et autre, que l'on produit en incorporant dans ladite structue une mousse polymère dont les alvéoles étaient initialement essentiellement fermées, mais qui a été travaillée de façon à ouvrir ces alvéoles, de sorte que la structure acquiert des caractéristiques absorbantes par rapport aux liquides. La mousse présente une masse volumique comprise entre 0,01 et 0,5 g/cm<3>. Le matériau présente des caractéristiques propices aux fonctions auxquelles le produit est destiné. La mousse peut se présenter sous forme d'une feuille qui peut être très mince et légère, avec un poids de surface compris entre 10 et 500g/m<2>. L'article sera ainsi très confortable à porter pour l'utilisateur, sa fabrication ne nécessitant qu'une faible quantité de matériau.
