Abstract:
The invention relates to the use of a urease inhibitor in an absorbent article to maintain the pH of the wearer's skin in a range of 4.0 to 6.0, wherein the urease inhibitor is provided between the topsheet and the absorbent core and/or is provided in the absorbent core. The invention also relates to absorbent articles comprising a urease inhibitor.
Abstract:
Superabsorbent fiber (SAF) in a feed stream is converted into soluble polymers in an extensional flow device. The total energy used to degrade the SAF into soluble polymers is less than about 50 MJ/kg SAF.
Abstract:
An absorbent core (28) for absorbent articles (20) such as diapers. The core comprises a core wrap (16, 16') comprising a top side (288) and a bottom side (290), an absorbent material (60) between the top side and the bottom side, a first and second longitudinally-extending channel-forming areas (26a, b) disposed on opposite sides of the longitudinal axis (80) and 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. The core has a central absorbent zone (62) between the first and the second channel-forming areas and a first and second lateral absorbent zones (61, 63) disposed laterally outwardly. The average basis weight of the absorbent material in the central absorbent zone is lower than the average basis weight of the absorbent material in the lateral absorbent zones.
Abstract:
An absorbent article (20) such as a diaper comprises a topsheet (24), a backsheet (25) and an absorbent core (28). The absorbent layer comprises at least a longitudinally-extending central portion (60), and a first and second side portions (61, 62) disposed transversally outward of the central portion. The absorbent core further comprises first and second folding guides (261, 262) between the central portion and the side portions. Each side portion comprises a plurality of winglets (610-613, 620-623), each winglet having a proximal side (6200, 6210, 6220) relative to a folding guide and extending outward from this proximal side, and wherein neighboring winglets are separated by a gap between their neighboring sides (6202-6211, 6213-6221). The central portion and the side portions form a three-dimensional basin when the absorbent core is folded along the folding guides. The article further may comprise at least one liquid management layer (52, 54) substantially free of superabsorbent polymer between the topsheet and the absorbent core. The absorbent core may be substantially free of cellulose fibers.

Abstract:
he present invention relates to a substrate which comprises oligogalacturonides. More particularly, the present invention provides a disposable absorbent article which comprises the substrate having the oligogalacturonides. The present invention also provides a process for manufacturing a disposable absorbent article comprising the substrate.
Abstract:
The present invention relates to a method, and a system using the method, for designing an absorbent article, and in particular evaluating its absorption behaviour. In particular, the invention provides a method for analyzing movement of a fluid in an absorbent article that comprises fluid- swellable composite material, to determine the performance of at least one feature of the absorbent article, said method comprising: a) inputting one or more properties for said fluid- swellable composite material into a virtual model of the absorbent article to produce a representation of at least one feature of the absorbent article; and b) evaluating the virtual model of the absorbent article to determine the performance of the at least one feature of the absorbent article. It also relates to a system using a computer that sues the method and model said out herein.
Abstract:
A disposable absorbent article having a chassis defining a front waist region, a rear waist region, and a crotch region disposed between the front waist region and rear waist region. The article includes a topsheet, an outer cover, and a core assembly disposed therebetween. The article further includes an anchoring system that includes an anchoring band, which may assume the form of a circumferential anchoring member that is configured to engage the wearer's body. The anchoring system further includes a load distribution element connected between the core assembly and the anchoring band to transfer load forces from the core to the wearer's body through the anchoring band.

Abstract:
This invention is directed to a process for making surface treated absorbent gelling material by treating partially swollen absorbent gelling polymers, which have a specific water content with a treatment agent, such as a coating agent, and subsequently removing at least part of the water. The treatment agent thus typically forms a shell on the polymers or part thereof, which can extend when the polymers swell in water; thus, the treatment shell or coating does not rupture when the polymers swell in a liquid, e.g. water or saline water, the coating being extensible in wet state. The treatment agent comprises preferably an elastomeric polymeric material. The invention also relates to surface-treated absorbent gelling material obtainable by the process of the invention, and to products, e.g. disposable absorbent articles, comprising such material.
