Abstract
An absorbent element for a disposable absorbent hygiene article for absorbing and storing body fluids, notably urine. The element includes an absorbent and distributing layer which, during use, is situated in proximity to the body and contains internally cross-linked cellulose fibers, and a storage layer which, during use, is situated away from the body and contains natural, non-cross-linked cellulose fibers and superabsorbant materials. The horizontal expansion of the absorbent and distributing layer situated close to the body is less than that of the storage layer and in all directions does not extend beyond the edges of the storage layer. The absorbent and distributing layer consists of internally cross-linked cellulose fibers having a first retention value of between 0.6 and 0.9 g / and between 8 and 15% by weight superabsorbant polymer materials and the storage layer consists of non-cross-linked cellulose fibers having a second retention value of between 1.0 and 1.4 g / and of at least 20% by weight superabsorbant polymer materials.
