    摘要： 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.

    摘要： A method for forming a composite absorbent member is provided that includes: a) extruding a first fibrous component through a first meltblowing die and intermingling pulp fibers with the first fibrous component to form a first admixture; b) extruding a second fibrous component through a second meltblowing die and intermingling pulp fibers with the second fibrous component to form a second admixture; and c) codepositing the first and second admixtures on a collecting surface so as to form a composite structure having at least a first layer and a second layer. The second layer has a higher weight percentage of pulp fibers than the first layer, and the average diameter of the pores within the second layer is smaller than the average diameter of the pores within the first layer.
