An absorbent article includes an absorber having a front surface side sheet, a back surface side sheet disposed on the back surface side of the front surface side sheet, cells each of which is surrounded by bonded portions of the front surface side sheet and the back surface side sheet and inside each of which the front surface side sheet and the back surface side sheet are not bonded, and particulate materials which include superabsorbent polymer particles and which are contained in each of the cells. The bonded portions are arranged in continuous line shapes or dotted line shapes so as to form same-sized regular hexagons, which connect each other as unit shapes to be a honeycomb shape. All the cells are the same-sized regular hexagonal cells each of which is surrounded by the bonded portions.

An absorbent core (28) for use in an absorbent article, the absorbent core extending in a transversal direction (x) and a longitudinal direction (y), the absorbent core comprising: a fluid-permeable top layer (41), a bottom layer (42), and a central layer (43) sandwiched between the top layer and the bottom layer. the central layer is a high loft fibrous nonwoven layer, in particular having a density of less than 0.200 g/cc, measured at a pressure of 4.14 kPa. Superabsorbent polymer particles (60) are blended with the fibers of the central layer, except for one, two or more longitudinally-extending channels (26) substantially free of superabsorbent polymer particles. The superabsorbent polymer particles may have a UPM of below 30×10.sup.−7 cm.sup.3.Math.s/g, wherein the UPM is measured by the Urine Permeability Measurement Test described herein.

The present invention discloses an absorbent article for attachment to the interior of a child potty/bed pan or to be worn on an user. The absorbent article composes an absorbent core, first absorbent channel layer, intermediate channel layer and top permeable layer composes made up of permeable materials and further includes a material capable of converting a liquid substance to a gel-like substance. Specifically, regions of the absorbent core first absorbent channel layer and intermediate channel layer may include a super absorbent polymer (SAP) material such as hydrogel, sodium polyacrylate, polyacrylate absorbents, or a biodegradable material such as a powder corn starch or wheat mixture or a combination of super absorbent polymer (SAP) and a biodegradable material.

A folded absorbent article includes an absorbent core sandwiched between a liquid-permeable topsheet and a liquid-impermeable backsheet. The absorbent article defines, in an unfolded and planar state, a longitudinal center line and a transverse center line. Each transverse side of the absorbent article is folded along a respective longitudinal fold line, such that each of first and second transversely opposed side edges are folded onto a topsheet surface of the absorbent article thereby forming a firstly folded absorbent article. The firstly folded absorbent article is thereafter folded along a first transverse fold line located in the region of the transverse center line thereby forming a secondly folded absorbent article. Finally, the secondly folded absorbent article is folded along a second transverse fold line located approximately in the middle between the transverse center line and a waist edge thereby forming a thirdly folded absorbent article.

An absorbent core (28) for use in an absorbent article (20) having a high loft central layer (43) between a top layer and a bottom layer and superabsorbent particles (SAP) at least partially distributed within the high loft layer. The superabsorbent polymer particles have a time to reach an uptake of 20 g/g (SAP T20) of less than 220 s, and/or the absorbent core has a time to reach an uptake of 15 g/g (Core T15) of less than 200 s, and/or the absorbent core has a permeability (core K20) of more than 6.0×10.sup.−8 cm.sup.2. These properties are measured according to the K(t) Test Method as described in the application.

An absorbent article includes a longitudinal axis extending in a longitudinal direction of the article, a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between the topsheet and backsheet. The absorbent core includes a combination of superabsorbent polymer and cellulose fibers. The article further includes an acquisition-distribution layer; and at least one channel positioned within a layer located between the topsheet and the backsheet, the at least one channel being substantially free of fibers and superabsorbent polymer. An indentation occurs in at least one of the topsheet and the backsheet that correspond to the at least one channels when the article is loaded with fluid.

A fluff pulp is provided, which comprises softwood fibers; and 3 to 35% by weight of hardwood fibers. A fluff is also provided, which comprises the fiberized or shredded fluff pulp. A core is also provided, which comprises the fluff and at least an SAP. Processes for making and using the fluff pulp, fluff, and core are provided, and products made thereby.

A disposable absorbent hygiene product is provided, including a main part having a body facing surface intended to face the body of a user and a garment facing surface intended to face away from the body of a user. The main part includes a liquid permeable topsheet at the body facing surface, a liquid impermeable backsheet at the garment facing surface, and an absorbent assembly arranged between the topsheet and the backsheet. The liquid permeable topsheet material includes a hydrophilically treated polypropylene spunbond nonwoven or spunbond/meltblown composite nonwoven, having a basis weight of from 8 to 20 g/m.sup.2. An acquisition layer material is provided sandwiched between said topsheet and said absorbent assembly, being an through air bonded nonwoven.

An absorbent article comprising a pair of leg cuffs with an raised section and an absorbent core comprising at least one channel at least partially oriented in the longitudinal direction of the article. The article may have a crotch width before use as measured between the proximal edges of the leg cuffs at the level of the crotch point of from to 70 mm to 200 mm, and a Relative Crotch Width Reduction (RCWR) of 32 mm/kg to 150 mm/kg.

A process of making an absorbent article is disclosed. A liquid permeable topsheet web extending substantially continuously in a machine direction a backsheet web, and an intermediate layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The intermediate layer has a first and second surface. The topsheet and intermediate layer are aligned in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the intermediate layer and simultaneously mechanically deformed which combines the topsheet with the intermediate layer. The topsheet web and intermediate layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the intermediate layer to provide a topsheet/intermediate layer laminate web having three-dimensional protrusions.
