Embodiments relate to reusable absorbent inserts, assemblies, and methods for use, the inserts including a configurable pad and pad collection sleeve. The configurable pad includes a first section and a second section, the second section separated from the first section at least partially by a folding guide. The configurable pad has an unfolded pad plan surface area comprising an unfolded pad width when the reusable absorbent insert is in an unfolded, flat-out configuration. The pad collection sleeve has an unfolded sleeve plan surface area including an unfolded sleeve width when the reusable absorbent insert is in an unfolded, flat-out configuration. The unfolded pad width is greater than or substantially equal to the unfolded sleeve width.

Reusable absorbent inserts and assemblies

A disposable absorbent article is provided having an absorbent core located in a chassis and including absorbent particulate polymer material defining at least one cavity. The absorbent core may be substantially cellulose free or comprise a combination of particulate absorbent polymer material and wood pulp. Methods for making such an absorbent core and corresponding disposable absorbent article are also disclosed.

Disposable absorbent article

An absorbent article comprising a liquid permeable topsheet, a backsheet, an absorbent core comprising an absorbent material and a core wrap is provided. The core comprises at least one channel-forming area that is substantially free of absorbent material. The absorbent article comprises a masking layer between the bottom side of the core wrap and the backsheet. The masking layer and the bottom side of the core wrap are only partially bonded to each other at their interface, the interface thus comprising a bonded portion and an unbonded portion, wherein the channel-forming area at least partially corresponds to the unbonded portion of the interface, so that when the absorbent material swells, the masking layer can decouple from the three-dimensional channels.

An absorbent article comprising a liquid permeable topsheet, a backsheet, an absorbent core comprising an absorbent material and a core wrap is provided. The article comprises an intermediate layer between the bottom side of the core wrap and the backsheet. The intermediate layer and the absorbent core are only partially bonded to each other at their interface and the interface comprises a bonded portion and a unbonded portion. The intermediate layer can at least partially decouple from the absorbent core in the unbonded portion, which increases flexibility of the article in the transversal direction.

A disposable absorbent article is provided having an absorbent core located in a chassis and including absorbent particulate polymer material defining at least one cavity for improved isolation of fecal matter or other body exudates. The absorbent core may be substantially cellulose free. Methods for making such an absorbent core and corresponding disposable absorbent article are also disclosed.

This invention is directed to super-absorbent material, which comprises a super absorbent polymer core that is coated with an organic, polar coating agent, and whereby the particulate super-absorbent material has a contact angle and a corresponding cos CA(as defined herein), whereby the cos CAis more than 0.3, and whereby, when said coating agent is in the form of particles, said coating agent particles have a (weight) mean particle size of from 0.001 to 1 micron. The material is useful for absorbent structures and absorbent articles (comprising such structures). The coated super-absorbent material is typically present in said absorbent structure at least at a concentration of 50% by weight of the structure, preferably even 80% or even 90%. The invention also provides a process for making the absorbent material.

The present invention relates to absorbent cores for absorbent articles, which are intended to receive and retain bodily discharges such as urine. Such articles are disposable hygiene articles like baby diapers, training pants, adult incontinence articles, feminine care articles and the like. The improvement essentially is based on the recognition that replacing most or all of the cushioning fibrous absorbent material in an absorbent core by a liquid storage material capable of retaining liquid while maintaining or improving acquisition behavior is desirable as the reduction in cushioning is more than compensated by the gain in comfort. The comfort however can only be achieved if the more fundamental requirements of a diaper in respect to liquid handling are satisfied or improved. Especially if this liquid handling performance is improved beyond the performance of conventional absorbent structures in order to allow creation of thinner and drier absorbent articles, the users of such articles would experience them as providing a more than expected comfort improvement relative to the thinness gain. To provide such absorbent cores and articles made therewith only became possible with the development of new highly absorbent gel materials capable of acquiring, conducting, and storing liquids in here-to-fore unexpected perfection at super absorbent polymer concentrations, which are unknown today. The second aspect allowing this breakthrough development is the ability to maintain the comfort and performance of such high super absorbent polymer concentration articles during the full usage cycle of the article, from dry to fully loaded, especially by improving the ability of the cores to withstand the forces experienced by such articles during use. This ability to remain intact is also often referred to as wet integrity of the core and its improvement is an important objective of the present invention.
