An absorbent article can have a topsheet layer, a liquid impermeable layer, and an absorbent core positioned between the topsheet layer and the liquid impermeable layer. The absorbent article can further include an exudate management layer in fluid communication with the topsheet layer. In various embodiments, the exudate management layer can be positioned on a body facing surface of the topsheet layer. In various embodiments, the exudate management layer can be positioned between the topsheet layer and the absorbent core. The exudate management layer has a first component which defines an opening for direct passage of body exudates into the absorbent core. The exudate management layer has a second component which at least partially overlaps the first component of the exudate management layer and further extends in the longitudinal direction of the absorbent article in a direction towards the posterior region of the absorbent article.

An absorbent core for absorbent articles such as diapers comprising a core wrap comprising a top side and a bottom side, an absorbent material between the top side and the bottom side of the core wrap, a first and second longitudinally-extending channel-forming areas disposed on opposite sides of the longitudinal axis and substantially free of absorbent material preferably through which the top side of the core wrap is preferably attached to the bottom side of the core wrap. The core has a central absorbent zone between the first and the second channel-forming areas and a first and second lateral absorbent zones disposed laterally outwardly. The basis weight of the absorbent material in the central absorbent zone is higher than the basis weight of the absorbent material in each of the lateral absorbent zones for at least a first transversal section (S1). This relation is inverted along a second transversal section (S2) of the core. The first and second sections have each a length in the longitudinal direction of at least 10 mm.

A signal layer for an absorbent article provided to absorb menstrual fluid includes a pattern of capillary channels allowing capillary action such that discharged menstrual fluid that comes across one of the openings in the capillary channels enters into the capillary channels and is retained therein due to the capillary force. The color of the retained menstrual discharge dyes or colors the pattern for signaling purpose, and the pattern is directly or indirectly visible to an observer.

The present invention relates to an absorbent core of an absorbent product including a liquid-permeable top sheet, an absorbent dispersion layer disposed at a lower portion of the top sheet, an absorbent core disposed at a lower portion of the absorbent dispersion layer and absorbing and retaining liquids, and a liquid-impermeable back sheet disposed at a lower portion of the absorbent core, and the absorbent core has effects of having the convenience of storage and the activity when an absorbent product prepared therefrom is worn by a user and improving liquid permeability compared to an existing absorbent core.

The present invention relates to an absorbing and distributing layer for a liquid to be absorbed, to a sheet material at least including a corresponding absorbing and distributing layer, to a hygiene article at least including a corresponding absorbing and distributing layer, to a method for producing a corresponding sheet material, and to the use of the corresponding absorbing and distributing layer.

An absorbent article includes a liquid permeable, apertured topsheet, a liquid impermeable backsheet, an absorbent core disposed at least partially intermediate the topsheet and the backsheet, and an acquisition material disposed at least partially intermediate the topsheet and the absorbent core. The acquisition material has a caliper in the range of about 2.5 mm to about 10 mm, according to the Caliper Test, and an Air Permeability in the range of about 5,000 l/m.sup.2/s to about 11,000 l/m.sup.2/s, according to the Air Permeability Test. The acquisition material has a first surface, a second surface, and a plurality of three-dimensional features extending outwardly from the first surface or the second surface.

A disposable absorbent article may include a chassis that includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet; and a leg gasketing system. The leg gasketing system may include an inner cuff and an outer cuff; the inner cuff may include an inner cuff folded edge and an inner cuff material edge and the outer cuff may include an outer cuff folded edge and an outer cuff material edge such that the web of material is folded laterally inward to form the outer cuff folded edge and folded laterally outward to form the inner cuff folded edge, and the leg gasketing system further including a leg gasketing system pocket with an opening on an inboard longitudinal edge of the leg gasketing system pocket. The disposable absorbent article also includes at least one channel in the absorbent core.

An absorbent article includes a liquid-permeable topsheet, a liquid impermeable backsheet and an absorbent core positioned intermediate the liquid permeable topsheet and the liquid impermeable backsheet, each layer having a skin-facing side, the absorbent article being arranged along a longitudinal axis and a transversal axis extending in a perpendicular direction in relation to the longitudinal axis, and the absorbent article defining a front portion having a front edge, a back portion having a back edge and a crotch portion intermediate the front portion and the back portion, wherein the back portion of the absorbent article further includes a transversally extending capture layer, wherein the capture layer includes an outboard transversal edge facing the back edge and two longitudinal edges being sealed to any part of the absorbent article, wherein the capture layer further includes an inboard transversal edge facing the front edge, the inboard transversal edge being unsealed for gathering of feces, wherein the capture layer is positioned to at least partially cover the skin-facing side of the topsheet, wherein the absorbent core includes at least one thickness, wherein at least the back portion of the absorbent article further includes at least one centrally oriented zone in the absorbent core, the zone being at least partially recessed, resulting in the zone having a generally lower thickness in relation to the thickness of surrounding parts of the absorbent core.

Embodiments disclosed herein are directed to negative pressure treatment systems and wound dressing systems, apparatuses, and methods that may be used for the treatment of wounds. In particular, some embodiments are directed to improved wound dressings comprising an obscuring layer that may hide fluid contained therein. Some embodiments may further comprise one or more viewing windows disposed therethrough so as to enable monitoring or examination of fluids contained therein.

A fluid distribution material for use in an absorbent article includes a formed film layer having a user-facing side and a garment-facing side opposite the user-facing side.
