Abstract: A system is provided for bifolding disposable absorbent articles on a high speed production line on which the disposable absorbent articles are moved along a predetermined path. The system includes the use of one or more vacuum conveyor assemblies to engage and transfer the leading end portion of the article from the surface of a peel-roll to a folding drum, thereby potentially reducing the occurrence of undesirable misalignment between opposing edges of an article during a bifolding process.

Abstract: An absorbent structure formed from a process of providing water-swellable material that includes water-swellable polymer particles, which are coated with a coating agent. The coating agent is a phase-separating elastomeric material that has a first and second glass transition temperature. The coated water-swellable polymer particles are able to swell without breakage of the coating.

Abstract: An SBS based construction adhesive that includes an amount of SIS adhesive to make an SBS/SIS adhesive that shows excellent shear hang time values when used to manufacture disposable absorbent articles. The SBS/SIS adhesive is applied in a spiral pattern having a particular width and frequency to form an endflap seal that may reduce the likelihood of a gel on skin occurrence.
Abstract: A method of surface treating particulate materials with electromagnetic radiation that is carried out with a so-called roll reactor comprising a rotating roll and an irradiation source. Radical former molecules can be applied on the surface of superabsorbent polymer particles, which are fed onto the surface of the roll and irradiated while moved with the rotating roll. The irradiation source is provided such that the radiation is able to reach at least part of the particulate material that has been fed onto the surface of the roll.

Abstract: An absorbent article includes a barrier cuff strip extending in a longitudinal direction from the front waist region to the back waist region along the topsheet. The barrier cuff strip has a distal edge attached to the topsheet at a cuff end bond region. The barrier cuff has an outer bond edge spaced longitudinally from an inner bond edge. The disposable absorbent article includes a side panel that extends laterally beyond a side of the chassis and is joined to the chassis at a panel joint region extending between an outer panel joint edge and an inner panel joint edge. The longitudinal distance from the lateral axis to the inner panel joint edge is at least about ¼ of a longitudinal distance from the lateral axis to the inner bond edge of the cuff end bond region.

Abstract: An absorbent article may comprise a topsheet, a backsheet joined with the topsheet, an absorbent core interposed between the topsheet and backsheet; and one or more article elements selected from the group consisting of an anal cuff, an elasticized topsheet, a fastening system, a leg cuff, a waist elastic feature, a side panel, an ear, and combinations thereof. The article elements may comprise a slow recovery stretch laminate exhibiting an unload force at 37° C. of about 0.16 N/(g/m) or greater and a percent of initial strain after 15 seconds of recovery at 22° C. of about 10% or greater.

Abstract: An absorbent member and a method for making such an absorbent member. The absorbent member includes a modified water absorbent resin having good production efficiency, absorbency against pressure, absorption speed, gel strength, and liquid permeability. The modified water absorbent resin may be made by mixing a water absorbent resin, water, and a water-soluble radical polymerization initiator without addition of an ethylenically unsaturated monomer to obtain a water absorbent resin composition, and irradiating the water absorbent resin composition with active energy rays. During irradiation, the surface water content of the water absorbent resin is at least 3.0 wt %.
Abstract: Superabsorbent polymer particles with improved surface cross-linking and their use in absorbent articles. The superabsorbent polymer particles comprise polymer chain segments, wherein at least a part of the polymer chain segments are covalently cross-linked to each other and wherein at least a part of the cross-links include the reaction product of cross-linking molecules having at least two C?C double bonds and further include the reaction product of radical former molecules. These cross-links are present at surfaces of the superabsorbent polymer particles.
Abstract: A method for designing an absorbent article and evaluating its absorption behaviour is disclosed. A system using the method, is also disclosed. The method may be used 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. The method includes 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 evaluating the virtual model of the absorbent article to determine the performance of the feature.

Abstract: A cleaning wipes container having one or more panels and a lid that covers an opening. The opening provides access to an interior storage space defined by the one or more panels. The interior storage space is configured to receive a wipes cartridge. The container also has a viewing area on at least a portion of one panel. The viewing area provides a target surface to join a transferable label. The transferable label includes indicia that relate to a characteristic of a type of cleaning wipes in the wipes cartridge. The indicia are viewable from outside the container.

Abstract: A process for simultaneously activating two or more portions of a web in different directions. The process involves feeding a web into an apparatus that includes a pair of intermeshing activation rolls having three dimensional surface features configured to simultaneously activate different portions a web in different directions. The three dimensional surface features are arranged in discrete regions on the rolls such that at least two of the regions provide different directions of activation. The rolls include one or more buffer regions positioned between the discrete regions on the roll that provide different directions of activation.
Abstract: Absorbent article, wherein a liquid acquisition/distribution region comprises an evaporation barrier, such as an apertured film and thus exhibits reduced evaporation away from the article in the direction towards the wearer.
