ABSORBENT ARTICLES WITH BIOCOMPOSTABLE PROPERTIES

Disclosed is an absorbent article with biocompostable properties, such as a baby diaper or adult incontinence product. Particularly, the present invention is directed to a biocompostable absorbent sanitary article including a blend of synthetic and bio-based superabsorbent polymers with a high degree of biocompostability. The sanitary article comprises, in one embodiment, at least a top layer, a back layer, and absorbent core, wherein the absorbent core includes a superabsorbent polymer, and wherein at least the superabsorbent polymer is biocompostable.

Unitary storage layer for disposable absorbent articles

A unitary storage layer for an absorbent article, being formed by at least two sub-layers in which a first outermost sub-layer forms said first surface and includes cellulose pulp fibers and cross linked cellulose fibers and includes less than 5% of SAP by weight of the sub-layer, and a second sub layer which includes cellulose pulp fibers and SAP and is immediately adjacent to said first sub-layer.

ABSORBENT CORE WITH PROFILED DISTRIBUTION OF ABSORBENT MATERIAL

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 disposed on opposite sides of the longitudinal axis and substantially free of absorbent material preferably through which the top side of the core wrap is preferably attached to the bottom side of the core wrap. 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 basis weight of the absorbent material in the central absorbent zone is higher than the basis weight of the absorbent material in each of the lateral absorbent zones for at least a first transversal section (S1). This relation is inverted along a second transversal section (S2) of the core. The first and second sections have each a length in the longitudinal direction of at least 10 mm.

COMPOSITE HAVING IMPROVED IN-PLANE PERMEABILITY AND ABSORBENT ARTICLE HAVING IMPROVED FLUID MANAGEMENT

The present disclosure features a composite fabric, including a nonwoven layer including polymeric fibers and/or filaments; a crosslinked cellulose layer including crosslinked cellulose fibers; wherein the crosslinked cellulose layer is positioned opposed to the nonwoven layer (e.g., without an intervening layer different from the crosslinked cellulose layer and the nonwoven layer; in some embodiments, the crosslinked cellulose layer is immediately adjacent to the nonwoven layer); and an interfacial region between the nonwoven layer and the crosslinked cellulose layer, the interfacial region including physically entangled polymeric fibers and/or filaments from the nonwoven layer and crosslinked cellulose fibers from the crosslinked cellulose layer. The nonwoven layer and the crosslinked cellulose layer of the composite fabric are mechanically inseparable in a dry state.

Absorbent articles with channels

The present disclosure is directed, in part, to an absorbent article comprising a topsheet, a backsheet and absorbent core positioned at least partially intermediate the topsheet and the backsheet. The absorbent core comprises an absorbent material positioned within a core wrap. The absorbent core defines a first channel therein. A material is positioned at least partially intermediate the topsheet and the core wrap. The material defines a second channel therein.

Disclosed is an absorbent article including: a laminate that has an absorbent containing water-absorbent resin particles and a fibrous material, and a core wrap sandwiching the absorbent from upper and lower sides of the absorbent; a liquid-permeable sheet disposed on an upper surface of the laminate; and a liquid-impermeable sheet disposed on a surface on a side opposite to the liquid-permeable sheet of the laminate. The water-absorbent resin particles satisfy the following requirements (a) and (b). (a) A surface drying index of the absorbent article represented by the following formula is 45 or lower.


Surface drying index=(moisture content index 1.5 minutes after liquid injection/moisture content index 1 minute after liquid injection)×100

(b) A water retention capacity of the water-absorbent resin particles for a physiological saline solution is 30 g/g or more.

Absorbent article with strong and weak bonded portions

An absorbent article includes an absorber including cells, each of which is surrounded by bonded portions of a front surface side sheet and a back surface side sheet and in each of which the front surface side sheet and the back surface side seat are not bonded, and including superabsorbent polymer particles contained in each of the cells. The bonded portions are arranged in dotted line shapes according to a pattern in which same-sized octagonal portions having all interior angles of 135°, and having two pairs of opposite sides whose facing directions are mutually orthogonal are equal in length, and diamond-shaped portions each having equal length of all sides and being formed in portions among the octagonal portions, are arranged without any space in the front-back direction (LD) or the width direction (WD).
