An embodiment of the present invention provides a water-absorbing sheet which, with respect to urine having a wide range of salt concentrations (mass %) including 0, has a favorable liquid absorption speed and favorable re-wet, and which has good comfortability for users, including infants, whose urine tends to change in salt concentration due to a change in the user's physical condition. In a water-absorbing sheet (10), a first particulate water-absorbing agent (12a) and a second particulate water-absorbing agent (12b) are localized, the first particulate water-absorbing agent (12a) has a gel permeation rate (GPR) which differs by 10 or more from that of the second particulate water-absorbing agent (12b), and the gel permeation rate of the second particulate water-absorbing agent (12b) is 50 or less.

A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.

The present invention generally relates to absorbent sanitary articles for absorption of body fluids and in particular to a sanitary article of this type including a buffer composition adapted to adjust the natural pH of the absorbed body fluid to a pH that is compatible with the pH of skin.

A disposable absorbent article may include a chassis that includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet; and a leg gasketing system. The leg gasketing system may include an inner cuff and an outer cuff; the inner cuff may include an inner cuff folded edge and an inner cuff material edge and the outer cuff may include an outer cuff folded edge and an outer cuff material edge such that the web of material is folded laterally inward to form the outer cuff folded edge and folded laterally outward to form the inner cuff folded edge. The leg gasketing system may also include a leg gasketing system pocket with an opening on an inboard longitudinal edge of the pocket.

Absorbent structure (13)s for absorbent articles are provided, comprising an absorbent layer (17) with absorbent material (50) containing superabsorbent polymer particles supported by a supporting sheet (16), and having first and a second substantially longitudinal channel (26) that are free of said superabsorbent polymeric particles, and that comprises one or more adhesive material to immobilize said absorbent material (50). The channels can provide improved fit and/or liquid acquisition/transportation, and/or improved performance.

A method for making a disposable absorbent core comprises depositing absorbent particulate polymer material from a plurality of reservoirs in a printing roll onto a substrate disposed on a grid of a support which includes a plurality of cross bars extending substantially parallel to and spaced from one another so as to form channels extending between the plurality of cross bars. The plurality of reservoirs in the first peripheral surface are arranged in an array comprising rows extending substantially parallel to and spaced from one another. A disposable absorbent article and apparatus for making an absorbent article are also disclosed.

Absorbent structures for absorbent articles are provided. The absorbent structure includes an absorbent layer with absorbent material supported by a supporting sheet, and a channel that is free of the absorbent material. The channel has a wet integrity of at least 20%.

The present invention relates generally to a system of producing a disposable absorbent article comprising a top sheet, a back sheet, an absorbent core positioned between said top sheet and said back sheet wherein said absorbent core having a core wrap that fully envelopes said absorbent core; said absorbent core comprises a mixture of fluff pulp and superabsorbent polymer (SAP) wherein said absorbent core having composition of SAP higher than composition of fluff pulp, and said SAP is having an Absorbency Under Load (AUL) above 17 g/g at 0.7 psi.

A diaper (10) includes an absorbent assembly (20) including a topsheet (21), a backsheet (22), and an absorbent core (24), and has an article longitudinal direction (X) and an article lateral direction (Y). The absorbent core (24) is formed of a sheet-like article (1) including a plurality of absorbent units (4), each including a long base portion (2) and water-absorbent polymer particles (3). The sheet-like article (1) includes a plurality of unit portions arranged in the longitudinal direction (x1 direction), each unit portion including a plurality of the absorbent units (4) arranged side by side in the lateral direction (y1 direction). The sheet-like article (1) includes a pair of longitudinal joined regions (41, 41), a pair of lateral joined regions (42, 42), and intermediate lateral joined regions (43, 43). The sheet-like article (1) is joined to a constituent member adjacent thereto in the thickness direction (Z) at the pair of longitudinal joined regions (41, 41), the pair of lateral joined regions (42, 42), and the intermediate lateral joined regions (43, 43). Each unit portion includes a section in which neither the upper side nor the lower side thereof in the thickness direction (Z) is joined to the constituent member.
