ABSTRACT:
An absorbent body for hygiene articles, particularly sanitary napkins or panty liners, includes a liquid absorbing and distributing layer facing the body and made of a first fibrous material with a first pore size, and a liquid storage layer facing away from the body and including at least 20 to 98 wt. % cellulose fibers, with a second pore size smaller than the first pore size. The first fibrous material is made of interlinked cellulose fibers, and the layers are interconnected, without adhesives by a multitude of embossing points provided in grid-like manner which results in the formation of a funnel-shaped pore gradient in the liquid absorbing and distributing layer around the embossing points. This pore gradient assists in the introduction of liquid into the underlying storage layer.
