The present disclosure is directed, in part, to an absorbent article comprising a liquid management system (LMS) and an absorbent core disposed at least partially intermediate a topsheet and a backsheet. The LMS defines one or more channels therein. The one or more channels of the LMS may at least partially overlap or not overlap with channels defined in the absorbent core.

An absorbent body forming satisfactory connections while webs are conveyed at a high speed includes at least two sheets of nonwoven fabric overlapping each other; connections at which the nonwoven fabric sheets are connected together; and an absorbent material disposed between the nonwoven fabric sheets at a small region encircled by the connections. When seen in a direction perpendicular to a main surface of the nonwoven fabric sheets, a plurality of the connections is formed with spaces therebetween on each side of imaginary polygons compartmentalizing the nonwoven fabric sheets and neighboring each other, and the connection is formed at least on a middle part of the sides common to the imaginary polygons neighboring each other. The connections are formed sequentially, and simultaneously arranged in a row parallel to each other, and the minimum number of connections per row is at least 45% of the maximum number of connections per row.

A disposable undergarment is disclosed. The undergarment includes a chassis and an absorbent core assembly. The chassis includes a front section, a crotch section and a rear section and elastic threads in those sections. The absorbent core is located in the crotch section, with portions of it extending into the front and rear sections. The core assembly includes a first or upper section of including plural pockets of a free slow acting but high absorbency SAP, and a second or underlying second section including plural pockets of a free fast acting by lower absorbency SAP. The SAP of the upper and lower sections exhibits various characteristics to facilitate to effective and efficient absorption of a fluid insult into the core assembly.

An absorbent article comprising an absorbent core having at least two longitudinally extending channel-forming areas and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid the core wrap forms channels along these areas substantially free of absorbent material. The wetness indicator is placed between the channel-forming areas or between at least one channel-forming area and at least one longitudinally extending side edge of the article, as seen for the exterior of the article.

An absorbent core assembly for use in a product for absorbing a liquid is disclosed. The core assembly has a first section and a second section. The first section is a quilted porous material that contains a slow acting but high absorption capacity SAP therein. The, second section is a quilted porous material that contains a fast acting but lower absorption capacity SAP therein. The first and second sections are in fluid communication with each other, whereupon a liquid which is exposed to the core assembly flows through the first section to the fast acting SAP in the second section to be absorbed quickly and rapidly by the fast acting SAP therein, while the slow acting SAP desorbs or takes liquid away from the fast acting SAP as well as absorbing the liquid itself to thereby trap the liquid in the core assembly.

An absorbent article includes a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core being disposed between the topsheet and the backsheet, wherein the absorbent core includes an absorbent material disposed in an absorbent deposition area and enclosed in a core wrap. The core further includes a first swelling chamber, a second swelling chamber, and an external zone. The absorbent material comprises superabsorbent polymer. One or more permanent seals separate the first swelling chamber and the second swelling chamber from the external zone. The swelling chambers consist of absorbent material immobilized by water-responsive bonds, wherein the water-responsive bonds deteriorate upon exposure to water such that the absorbent material is flowable in the wet state; and the external zone comprises absorbent material that is immobilized by thermoplastic adhesive, such that the absorbent material is immobilized in the wet state.

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.

An absorbent article comprising an absorbent core having a longitudinally extending channel-forming area and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid a channel is formed along the area substantially free of absorbent material.

Absorbent articles herein may provide a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet. The absorbent core may comprise at least one channel having a shape. The backsheet graphics may substantially match the shape.

The present disclosure provides articles having an absorbent core with a plurality of segmented volumes defined by a network of filaments, with an absorbent material therein. Suitable articles which may be formed with this absorbent core include, for example, diapers such as infant diapers, juvenile diapers and training pants, feminine hygiene products such as menstrual pads, adult incontinence products such as adult briefs, protective underwear, pads and bladder control pads, pet training pads, and other disposable products utilized to absorb fluids.
