Abstract
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/cm.sup.3. 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/m.sup.2, and the article will therefore exhibit good comfort properties to the wearer and requires only a small amount of material for its manufacture.
