Absorbent article with microencapsulated phase change material
An absorbent article is provided with microencapsulated phase change material (microPCM) particles that are embedded in and/or coated onto a layer of the absorbent article that includes a resilient sheet of an open-cell foam. The foam layer is disposed such that it is in contact with or is in proximity to the user. The microPCM particles absorb heat generated during use of the absorbent article to reduce the contact temperature on the inside of the absorbent article and improve the comfort of the user. To maximize comfort, the phase change temperature of the microPCM particles may be an average normal body temperature.
Absorbent products comprising foam material
An absorbent product includes a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core enclosed between the topsheet and the backsheet. The absorbent core includes an absorbent fibrous layer and a liquid inlet foam layer and the absorbent core includes a transversally central liquid inlet region extending in the longitudinal direction of the absorbent core. Within the liquid inlet region, the liquid inlet foam layer is covered by a plurality of inlet openings and has a transversal width, which is equal to, or up to 9 mm smaller than, the minimum transversal width of the absorbent fibrous layer. The liquid inlet foam layer also has side edge regions arranged in front and rear portions of the absorbent core transversally outside of the liquid inlet region, and within which the liquid inlet foam layer is free from liquid inlet openings.

ABSORBENT ARTICLES WITH DIFFERENT TYPES OF CHANNELS
An absorbent article has a front side, a back side, a longitudinal axis, a liquid permeable topsheet, a liquid impermeable backsheet and an absorbent core between the topsheet and the backsheet. The absorbent core includes a first type of channels, wherein the top side and the bottom side of the core wrap are bonded to another, and a second type of channels, wherein the top side and the bottom side of the core wrap are not bonded or are less bonded to one another in this second type of channels than in the first type of channels. The absorbent material may also include cellulose and superabsorbent particles.
ABSORBENT ARTICLE WITH FUNCTION-FORMED TOPSHEET, AND METHOD FOR MANUFACTURING
An absorbent article is disclosed. The article includes a topsheet formed of a section of formed nonwoven web material having an ordered arrangement of zones, each zone comprising one or more attenuated regions adjacent to one or more built-up regions, wherein the attenuated regions have a first average basis weight and the built-up regions have a second average basis weight, wherein the first average basis weight is less than the second average basis weight, the difference in basis weights corresponding to disposition of the filaments according to the ordered arrangement. The attenuated region(s) may include a plurality of discrete low bulk portions arranged in a pattern disposed along a longitudinal axis of the article, which facilitate z-direction movement of fluid through the topsheet and inhibit spreading of a fluid stain along the topsheet in the x and y directions.

The present disclosure generally relates to an absorbent pad for use in a garment and a garment having the absorbent pad. The absorbent pad includes a liquid impermeable barrier layer; a functional assembly attached to the barrier layer; and a peripheral assembly attached to a periphery of the functional assembly, at least part of the peripheral assembly being liquid impermeable. The functional assembly includes an absorbent layer attached to the barrier layer, the absorbent layer for absorbing liquid; and a wicking layer attached to the absorbent layer. The wicking layer is arranged to face towards a skin of a user when in use. The wicking layer transfers liquid to the absorbent layer. The wicking layer and the absorbent layer are attached at a plurality of discrete points between them to facilitate liquid transfer from the wicking layer to the absorbent layer via areas around the discrete points.
ABSORBENT ARTICLES WITH CHANNELS
The present disclosure is directed, in part, to an absorbent article that comprises 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 substantially free of superabsorbent polymers. The one or more channels of the LMS may at least partially overlap channels defined by the absorbent core. The absorbent article may comprises a liquid distribution system (LDS) that defines one or more channels.
Absorbent articles with channels
The present disclosure is directed, in part, to an absorbent article that comprises 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 substantially free of superabsorbent polymers. The one or more channels of the LMS may at least partially overlap channels defined by the absorbent core. The absorbent article may comprises a liquid distribution system (LDS) that defines one or more channels.
ABSORBENT ARTICLES WITH DIFFERENT TYPES OF CHANNELS
An absorbent article has a front side, a back side, a longitudinal axis, a liquid permeable topsheet, a liquid impermeable backsheet and an absorbent core between the topsheet and the backsheet. The absorbent core includes a first type of channels and a second type of channels. The first type of channels have bonds with a Static Peel Force Time which is higher than the Static Peel Force Time of the second type of channels.
ABSORBENT ARTICLES WITH DIFFERENT TYPES OF CHANNELS
An absorbent article has a front side, a back side, a longitudinal axis and includes a liquid permeable topsheet on the wearer-facing side, a liquid impermeable backsheet on the garment-facing side, and an absorbent core between the topsheet and the backsheet. The absorbent core includes a core wrap having a top side and a bottom side, an absorbent material having a deposition area between the top side and the bottom side of the core wrap, and at least two channels substantially free of absorbent material within the deposition area. In a first type of channels, the top side and the bottom side of the core wrap are bonded to each other. In a second type of channels, the top side and the bottom side of the core wrap are not bonded or are less bonded to each other than in the first type of channels.
