This absorbent core is useful for providing an absorbent article of increased wearing comfort. Specifically disclosed is an absorbent core useful for an absorbent article comprising a substrate layer and absorbent material, the absorbent material comprising an absorbent polymer material, the absorbent material optionally comprising absorbent fibrous material, the absorbent fibrous material not representing more than 20% of the weight of absorbent polymer material, wherein the absorbent material is immobilized by a thermoplastic fibrous material.

Absorbent structure for absorbent articles

Absorbent structures for diapers are provided, comprising, immobilized onto a supporting sheet, an absorbent layer with absorbent material containing superabsorbent polymer particles and therein, in the front region, a first and a second substantially longitudinal channel, each being free of said superabsorbent polymeric particles, for improved fit and/or performance throughout the use thereof.

Disposable absorbent article with profiled absorbent core

A disposable absorbent article has a central body defining a first waist end region including a first end edge, a second waist end region spaced longitudinally from the first waist end region and including a second end edge, and a crotch region positioned therebetween. An absorbent core is situated between the end edges, and includes a plurality of elastics incorporated therewith such that the core is substantially laterally contracted in a narrowed region about the elastics. The absorbent core includes at least one end region that is substantially non-elasticized and has a lateral width substantially wider than that of the narrowed region.

Absorbent core comprising a high loft central layer and channels

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.

An absorbent body having elasticity in a plurality of directions is provided. The absorbent body according to an embodiment of the present invention includes a first elastic member, a second elastic member, and an absorbing member laminated between the first elastic member and the second elastic member, wherein the first elastic member forms, together with the second elastic member, a plurality of housing parts, and the plurality of housing parts are delimited from each other by a first delimiting part along a first direction and a second delimiting part along a second direction intersecting the first direction, and house the absorbing member.

Absorbent composite, an absorbent article employing the same, and methods, systems, and apparatus for making the absorbent composite and/or article

An absorbent core composite is disclosed for incorporation into a disposable absorbent article. The composite includes a first material layer and a second material layer (preferably nonwoven) partially secured to the first material layer to define at least one pocket therebetween. Preferably, multiple pockets are defined, except in the case of where a generally uniform layer or bed of absorbent is preferred or better suited for the application. The pocket is said have a fixed initial volume. Further, an aggregate of absorbent particles is provided in the pocket(s) to occupy a portion of the fixed initial volume. The absorbent particles are preferably SAP particles and is characterized by a dry volume associated with a dry state and a swell volume associated with a liquid saturation state. In respect to or for the pocket, the aggregate is characterized by a collective dry volume and a collective swell volume, wherein the pocket has an initial configuration that retains the aggregate therein.

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.

ABSORBENT ARTICLE WITH HIGH ABSORBENT MATERIAL CONTENT

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.

ABSORBENT ARTICLE AND METHOD FOR MANUFACTURING AN ABSORBENT ARTICLE

An absorbent article comprises an absorbent core sandwiched between a liquid-permeable topsheet and a liquid-impermeable backsheet, wherein the absorbent core includes an absorbent component enclosed by a core cover including an upper side and a lower side, each side having a body facing surface and a garment facing surface, and a sealing arrangement for joining the upper and lower sides and including two channel sealings in the crotch portion defining a first channel sealing width and a second channel sealing width. The channel sealings are formed by an ultrasonic welding pattern including a plurality of welding spots and the garment facing surface of the upper core cover side and the body facing surface of the lower core cover side are coated with adhesive, provided that the areas of the channel sealings are free from adhesive.
