The present invention relates to an absorbent structure and an absorbent article containing said absorbent structure. The absorbent structure, having a sequence of layers connected together, comprises a first outer absorbent layer made from airlaid material, a second outer absorbent layer made from airlaid material, and a fluid storage layer made from airlaid material arranged between the first and second outer absorbent layers, wherein the airlaid material of the first outer absorbent layer comprises first cellulose fibres, the airlaid material of the second outer absorbent layer comprises second cellulose fibres and the airlaid material of the fluid storage layer comprises third cellulose fibres and super-absorbent components, wherein the first and second cellulose fibres have a lower pH value than the third cellulose fibres and the pH value of the first and second cellulose fibres is less than 5.0.

In a particular implementation, an absorbent article includes a chassis having opposing front and rear waist portions and a crotch portion extending longitudinally between the front and rear waist portions. The crotch portion is configured to conform about at least one of a wearer's groin area, perineum, and rear when the chassis is configured in a wearable configuration. The absorbent article also includes an absorbent core extending longitudinally along the crotch portion and including a laminate The laminate is longitudinally folded such that the absorbent core includes a lower layer spanning a portion of a lateral width of the absorbent core. The lower layer includes a first portion and a second portion. The absorbent core also includes a plurality of folded layers of the laminate disposed over the lower layer and configured to define one or more non-overlapping channels.

The present disclosure relates to absorbent garments having a dryness layer that can comprise one or more laminates and one or more channels to facilitate liquid acquisition and retention. Laminate(s) can include an absorbent lamina disposed between substrate laminae, each comprising tissue and/or a nonwoven. Some dryness layers can have a folded laminate that defines a longitudinally-extending channel. Some dryness layers can have two or more laminate strips that are laterally spaced apart along a width of the dryness layer such that one or more longitudinally-extending channels are defined therebetween.

An absorbent article comprising a topsheet, a backsheet, and a layer of absorbent material interposed between the topsheet and the backsheet, wherein the layer of absorbent material (28) comprises superabsorbent polymer. The absorbent article further comprises a lower acquisition and distribution system with at least one nonwoven or woven layer, the lower acquisition and distribution system being interposed between the layer of absorbent material and the backsheet. The absorbent article has a first zone corresponding to 800 μm starting from and including the topsheet and extending towards the backsheet, and a second zone corresponding to 800 μm starting from and including the backsheet and extending towards the topsheet. The amount of liquid in the first and second zone is very small as measured by the NMR test method set out herein.

An absorbent core comprising: a front portion; a back portion; a middle portion positioned between the front portion and the back portion; and a longitudinal axis extending along a length of said core and crossing said front, middle and back portions, the absorbent core having a width extending perpendicular to said length and a perimeter comprising at least two opposing ends and at least two opposing sides positioned between said ends, said core being a multi-layer core comprising at least two distinct core layers, wherein a first core layer comprises a channel having a first shape and a second core layer comprises a further channel having a second shape and wherein the first and second core layers are disposed one on top of the other such that a third channel shape is formed along said core length and width, and wherein said first and second shapes are substantially the same and are different to said third shape.

The present invention relates to a layered absorbent structure in the form of a laminate including liquid storage layers comprising particulate superabsorbent material and adhesive fibers. Notably, the absorbent structure includes a wicking layer positioned between the liquid storage layers, with the wicking layer desirably acting to improve fluid spreading and rewet performance of the absorbent structure. The wicking layer preferably comprises airlaid cellulosic fibrous material such as wood pulp, and may optionally include superabsorbent polymer. A bonding pattern of the wicking layer is oriented to enhance wicking and rewet performance.
