An absorbent article. The absorbent article includes a topsheet having a body contacting surface, a backsheet joined to said topsheet, and an absorbent core disposed between the topsheet and the backsheet, wherein the absorbent core has an upper layer and a lower layer.

A medical device including a plasma-treated porous substrate that is functionalized to provide a hydrophilic surface, and a process for preparing such a medical device, are disclosed. The method includes plasma treating at least a portion of a surface of a porous substrate with a gas species selected from oxygen, nitrogen, argon, and combination thereof. The gas species is configured to functionalize the surface of the medical device and form a hydrophilic surface.

As absorbent article for absorbing urine includes a topsheet which is a nonwoven fabric that has a skin-side surface having projections formed thereon. The content by percentage of fibers oriented in the thickness direction in each projection of the nonwoven fabric is greater than the content by percentage of fibers oriented in the thickness direction in sections of the nonwoven fabric other than the projections. The thickness of the nonwoven fabric when wet is greater than or equal to 85% the thickness of the nonwoven fabric when dry. The nonwoven fabric includes a first fiber layer and a second fiber layer. The first fiber layer is constituted by durable hydrophilic fibers, and the second fiber layer is constituted by durable hydrophilic fibers and non-durable hydrophilic fibers.

An absorbent product includes a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core enclosed between the topsheet and the backsheet. The absorbent core includes an absorbent fibrous layer, a liquid inlet layer, and a carrier layer, in which a transversally central region is arranged in the liquid inlet layer. The central region extends along the entire longitudinal length of the absorbent core, and includes a plurality of slits arranged in a pattern. The slits are in the form of dilated slit openings in a part of said central region, which is comprised in an intermediate portion of the absorbent core, and the slits are in the form of non-dilated slits in parts of said central region, which are comprised in one or both of front and rear portions of the absorbent core.

An absorbent article comprising an absorbent core comprising an absorbent material between a top core wrap and a back core wrap, said absorbent core having a first and second longitudinal edge and a first and second transverse edge; the absorbent core comprising at least a front and a rear attachment zone, and a bridging zone extending at least partially between said front and rear attachment zone, wherein the bridging zone extends from a first longitudinal portion of the absorbent core to a second longitudinal portion of the absorbent core, such that upon wetting of the absorbent material, a front and rear channel are created at said front and rear attachment zone, respectively, wherein the bridging zone allows a liquid flow between the first longitudinal portion and the second longitudinal portion.
