Abstract
The invention pertains to an absorbent structure for an article of personal hygiene such as a diaper, sanitary napkin or incontinence product or for a medical product such as bandage material, having a top ply (18) facing the body and a bottom ply (22) underneath it. To improve the fluid absorption capacity of the structure so that even after more than one discharge of fluid the absorbent structure remains drier on the side facing the body, the invention proposes that the top ply has an upper layer (26) and, situated between upper layer and bottom ply, a lower layer (28) that contains a superabsorbent material (29). The bottom ply consists essentially of cellulose fibers only. The absorption capacity of the cellulose fibers of the upper layer is markedly lower than that of the cellulose fibers of the layers underneath. Between the two layers of the top ply a transition zone (30) can be formed, containing a mixture of the fibers of the two layers and the superabsorbent material.
