Dryness layer laminate for absorbent articles

The present disclosure relates to absorbent garments having a dryness layer that can comprise one or more laminates and one or more channels to facilitate liquid acquisition and retention. Laminate(s) can include an absorbent lamina disposed between substrate laminae, each comprising tissue and/or a nonwoven. Some dryness layers can have a folded laminate that defines a longitudinally-extending channel. Some dryness layers can have two or more laminate strips that are laterally spaced apart along a width of the dryness layer such that one or more longitudinally-extending channels are defined therebetween.

Provided is an absorbent article capable of fully utilizing absorption capacity of an absorption layer downstream in a liquid supply direction in a structure in which a plurality of absorption layers are laminated. An absorbent article-includes a first absorption layer and a second absorption layer configured to absorb liquid, and a diffusion layer that is interposed between the first absorption layer and the second absorption layer and diffuses the liquid in a direction in which a plane of the second absorption layer spreads. The first absorption layer includes an absorbent resin configured to absorb liquid. The first absorption layer includes an absorption region including the absorbent resin, and a passage region that has a lower density of the absorbent resin than a density of the absorbent resin in the absorption region. The passage region allows the liquid to pass through the diffusion layer.
