An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.

An apparatus for manufacturing an absorbent body according to the present invention includes a conveying unit (2) that conveys an aggregate (101) of absorbent fibers and a water-absorbent resin (102), a mixing unit (3) that accepts the aggregate of the absorbent fibers and the water-absorbent resin that were conveyed by the conveying unit and mixes the absorbent fibers and the water-absorbent resin, a chamber portion (4) that has an internal space (40) through which the absorbent fibers and the water-absorbent resin that were mixed in the mixing unit fall, a stacking portion (5) that is disposed below the chamber portion and has a recessed portion (531) in which the absorbent fibers and the water-absorbent resin that fall through the chamber portion are stacked, and a suction unit (6) that causes a negative pressure in the chamber portion.

To provide an absorbent pad, the absorbent pad being formed of an inner absorbent pad which is positioned on the body-side and an outer absorbent pad positioned on the non-body side, wherein when the inner absorbent pad absorbs liquid excretions and swells, openings are provided at the side which is indented furthest towards the non-body side, improving the passage of liquid, and improving the dispersion of sites facing the openings in the outside absorbent pad, preventing leakage of liquid excretions to the exterior.

An absorbent structure for an absorbent article, comprising a first substrate and an absorbent layer supported thereon, said absorbent layer comprising an absorbent material comprising a superabsorbent polymer material; wherein said absorbent structure comprises a fiberized net structure to at least partially immobilize said absorbent layer onto said first substrate, and whereby said fiberized net structure has a storage modulus (G) at 21 C. of greater than about 1.210.sup.6 Pa.

An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.

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 wherein the absorbent core comprises one or more channels having a first shape when the absorbent core is in dry state and a second shape when the absorbent core is in wet state and wherein said first and second shapes are different.

An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.

The present invention discloses a absorbent article configured for attachment to the interior of an 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 comprises an material capable of converting an liquid substance to an gel-like substance. Specifically, regions of the absorbent core first absorbent channel layer and intermediate channel layer may comprise an super absorbent polymer (SAP) material such as hydrogel, sodium polyacrylate, polyacrylate absorbents, or an biodegradable material such as an powder corn starch or wheat mixture or an combination of super absorbent polymer (SAP) and an biodegradable material.

Absorbent articles and absorbent core structures with improved core strength and stability with long core end seal and channel hang times.

A thin absorbent composite is provided wherein a nonwoven support sheet is hydro-entangled with a carded fiber web to provide a nonwoven substrate. The nonwoven substrate is coated with an absorbent layer comprising microfibrillated cellulose-coated superabsorbent polymer particles. A cover layer is placed above the absorbent layer to provide the absorbent composite. A process for manufacturing the absorbent composite and an absorbent article containing the absorbent composite are also provided.
