Abstract: An absorbent core for use in an absorbent article, the absorbent core extending in a transversal direction and a longitudinal direction. The absorbent core includes a fluid-permeable top layer, a bottom layer, and a middle layer between the top layer and the bottom layer. The middle layer may be a high loft fibrous nonwoven layer, in particular having a density of less than about 0.200 g/cc, measured at a pressure of 4.14 kPa. Superabsorbent polymer particles may be blended with the fibers of the middle layer, except for one or more longitudinally-extending channels substantially free of superabsorbent polymer particles.

Abstract: 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.

Abstract: An absorbent article includes a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core being disposed between the topsheet and the backsheet, wherein the absorbent core include san absorbent material disposed in an absorbent deposition area and enclosed in a core wrap. The core further includes a swelling chamber disposed in between two external zones. The absorbent material comprises superabsorbent polymer. One or more permanent seals separate the chamber from each of the two external zones. The swelling chamber consists of absorbent material immobilized by water-responsive bonds, wherein said water-responsive bonds deteriorate upon exposure to water such that the absorbent material is flowable in the wet state; and the two external zones comprise absorbent material that is immobilized by thermoplastic adhesive, such that the absorbent material is immobilized in the wet state.

Abstract: A sanitary napkin is disclosed having a body-facing surface and a garment-facing surface. The sanitary napkin also has a first end, a second end, and a pair of sides. The sanitary napkin has a longitudinal central axis, a transverse central axis, a main absorbent, and first and second 3-dimensional absorbent members. The main absorbent, and the first and second 3-dimensional absorbent members are joined together between a liquid pervious top sheet and a liquid-impervious back sheet. All three absorbents contain superabsorbent. The sanitary napkin also has a pair of wings extending outward from the sides of the sanitary napkin and has garment adhesive on the garment facing surfaces to secure the sanitary napkin and the pair of wings to the crotch portion of an undergarment. This sanitary napkin is designed to absorb heavy to excessive menstrual fluid flow.
