  • Publication number: 20180008487
    Abstract: Absorbent cores comprising a core wrap which comprises a liquid permeable substrate layer, the core containing from about 87% to about 100% of superabsorbent polymer and having a funnel-shaped swelling chamber. The area of the core is at least twice the area of the swelling chamber, and the core contains a water responsive immobilizing agent to immobilize the superabsorbent polymer prior to water insult. The funnel-shaped swelling chamber is a portion of the absorbent core containing superabsorbent polymer and delimited by continuous permanent seals. Two permanent continuous seals form first opposing funnel wall segments, wherein first opposing funnel wall segments collectively comprise a first chamber angle about 20° to about 120°, the first chamber angle being the sum of angles formed by each first opposing wall segment with respect to the longitudinal axis.

  • Publication number: 20180008486
    Abstract: An absorbent cores includes absorbent material enclosed a core wrap which comprises a liquid permeable substrate layer. The core contains from about 87% to about 100% of superabsorbent polymer and a tube-shaped swelling chamber having a length to width aspect ratio of less than or equal to about 5:1. The area of the core is at least twice the area of the swelling chamber, and the core contains a water responsive immobilizing agent to immobilize the superabsorbent polymer prior to water insult. The tube-shaped swelling chamber is a portion of the absorbent core containing superabsorbent polymer that is delimited by a plurality of continuous permanent seals that each join together overlapping portions of the core wrap and prevent superabsorbent polymer from moving across the seals.

  • Publication number: 20170312147
    Abstract: An absorbent core for absorbent articles such as diapers comprising a core wrap comprising a top side and a bottom side, an absorbent material between the top side and the bottom side of the core wrap, a first and second longitudinally-extending channel-forming areas substantially free of absorbent material preferably through which the top side of the core wrap is attached to the bottom side of the core wrap disposed on opposite sides of the longitudinal axis. The core has a central absorbent zone between the first and the second channel-forming areas and a first and second lateral absorbent zones disposed laterally outwardly. The absorbent core comprises at least one transversal folding line, preferably at least two transversal folding lines, in the region where the longitudinally-extending channel-forming areas are present.
