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.

The presently disclosed subject matter relates to multi-layer nonwoven materials and their use in absorbent articles. More particularly, the presently disclosed subject matter relates to layered structures that have high absorbency performance while having less absorbent mass than other commercially available materials.

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.

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.

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. The absorbent core is located in the crotch section, with portions of it extending into the front and rear sections. A large plurality of closely spaced elastic threads extends across the full width of the undergarment in the front and rear sections. A large plurality of closely spaced elastic threads extends across the full width of the undergarment in portions of the crotch section adjacent the front and rear sections. The elastic threads are broken in the areas of the core assembly. The core assembly includes a first section of a slow acting but high absorbency SAP in pockets thereof and an underlying second section of a fast acting by lower absorbency SAP in pockets thereof.

The present disclosure describes absorbent articles that include an absorbent core. The absorbent core extends longitudinally along a crotch portion of the absorbent article. The absorbent core includes a channel having one or more pathways extending longitudinally along the absorbent core. The channel is substantially free of absorbent material. In some implementations, the channel includes a single pathway. In other implementations, the channel includes multiple pathways.

An absorbent article is worn to receive discharged urine of the wearer. The article includes a liquid-permeable top sheet, an intermediate liquid-absorbent layer, a bottom sheet including at least one indicator and a liquid-impermeable backing layer. Each of the at least one externally visible indicator is coated or impregnated with at least one chemical reagent facing the liquid-absorbent layer. Each of the at least one chemical reagent is configured to undergo a change in color or shade from a plurality of different possible color or shade changes of the reagent upon contact with the discharged urine. Each color or shade is associated with a corresponding level of an analyzed component or with the presence or absence of the analyzed component and the change in color or shade of the at least one chemical reagent is externally visible on the indicator through the bottom sheet and the backing layer.

Disposable absorbent articles having color effects and materials thereof are disclosed. Disposable absorbent articles include a topsheet; a backsheet; an absorbent core between the topsheet and the backsheet; and a layer between the absorbent core and the topsheet. The topsheet has a generally planar first surface having a plurality of out-of-plane features and a first color. The layer has a second color. And, the plurality of out-of-plane features have a feature color different than the first color and the second color.
