10813799 · 2020-10-27 · ·

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.

An absorbent article comprising a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core comprising an absorbent material between a top core wrap sheet and a back core wrap sheet, said absorbent core being positioned in between said topsheet and said backsheet, said absorbent core having a first and second longitudinal edge and a first and second transverse edge, said absorbent core having a first portion (130a), (130b) and a second portion (130b), (130a) on either side of a transverse crotch line (L), wherein the absorbent core is provided with a plurality of attachment zones where the top core wrap sheet is attached to the back core wrap sheet, wherein, measured in a transverse direction, a first maximum distance between a first and a second attachment zone is bigger than a second maximum distance between a third and a fourth attachment zone.

ABSORBENT ARTICLE WITH CORE-TO-BACKSHEET GLUE PATTERN COMPRISING TWO GLUES

An absorbent article comprises a topsheet on the wearer-facing side, a backsheet on the garment-facing side, and an absorbent core positioned between the topsheet and the backsheet. The absorbent core comprises an absorbent material comprising a superabsorbent polymer, a core wrap enclosing the absorbent material, and a first channel disposed on one side of the longitudinal axis and a second channel disposed on the other side of the longitudinal axis.

Flexible absorbent pad

A flexible absorbent pad has a dry thickness of between 2 mm and 10 mm and a difference in flexural-resistance between the dry state and the wet state of an absorbent center zone of the absorbent pad of less than 100 grams-force. The absorbent core of the pad may include an airlaid, a foam, or a fibrous staple filament. The absorbent core of the absorbent pad may be corrugated, such as with flexure hinges, in which case adhesive is applied to the backsheet of the absorbent pad in a pattern that leaves the flexure hinges devoid of adhesive so that the backsheet is attached to the absorbent core in a manner that does not impede the flexing of the flexure hinges.
