The present disclosure generally relates to disposable diapers having absorbent cores comprising superabsorbent polymer particles which are immobilized by adhesive. The absorbent cores are attached to the backsheets of the disposable diapers in certain attachment zones to reduce see-through and the formation of tension lines on the backsheets.

An absorbent article including a wearer-facing topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet, characterized in that the absorbent core includes: a first absorbent layer comprising a first substrate, a layer of first superabsorbent polymer particles deposited on the first substrate, and a fibrous layer of thermoplastic adhesive material covering the layer of first superabsorbent polymer particles; a second absorbent layer, the second absorbent layer comprising a second substrate and a mixed layer deposited on the second substrate, the mixed layer comprising a mixture of second superabsorbent particles and cellulosic fibers, the first absorbent layer and the second absorbent layer being combined together such that at least a portion of the fibrous layer of thermoplastic adhesive material of the first absorbent layer contacts at least a portion of the mixed layer of the second absorbent layer, and wherein the first absorbent layer is placed closer to the topsheet than the second layer.

An absorbent article includes a three-dimensional material on the wearer-facing side and an absorbent core with a material-free channel. The three-dimensional material comprises a fibrous support layer, a fibrous projection layer and a plurality of hollow projections formed from a first plurality of fibers in the projection layer.

An absorbent article that is toxin-free and made from plant-based, biobased, all natural, clean ingredients. In one embodiment, the absorbent article is a diaper made from plant-based resin, comprising: (i) a first layer, wherein the first layer is a cotton top sheet with a wax-based coating deposited on an exterior surface of the first layer (adjacent to the wearer's skin, or user-facing); and (ii) a second layer, wherein the second layer is an acquisition/distribution layer (ADL), and wherein the ADL is comprised of two sub-layers of different materials, a first sublayer comprising an apertured film acquisition sub-layer disposed on top of, and laminated to, a second sub-layer comprising a non-woven acquisition layer.

An absorbent article that can be a sanitary napkin. The absorbent article comprises a topsheet joined to a backsheet and has an absorbent core material disposed therebetween, the absorbent core material being a fibrous absorbent material exhibiting on one side thereof discrete raised portions. The raised portions define a continuous network of channels, the channels defining a void region adjacent the topsheet of the sanitary napkin.

An absorbent article comprising a wearer-facing topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet, characterized in that the absorbent core comprises: a first absorbent layer comprising a first substrate, a layer of first superabsorbent polymer particles deposited on the first substrate, and a fibrous layer of thermoplastic adhesive material covering the layer of first superabsorbent polymer particles; a second absorbent layer, the second absorbent layer comprising a second substrate and a mixed layer deposited on the second substrate, the mixed layer comprising a mixture of second superabsorbent particles and cellulosic fibers, the first absorbent layer and the second absorbent layer being combined together such that at least a portion of the fibrous layer of thermoplastic adhesive material of the first absorbent layer contacts at least a portion of the mixed layer of the second absorbent layer, and wherein the first absorbent layer is placed closer to the topsheet than the second layer.

Absorbent articles, such as channeled core diapers, including (i) a topsheet; (ii) an acquisition distribution layer (ADL) comprising a first spunbond nonwoven comprising a first plurality of hydrophilic polyolefin fibers, wherein the ADL has a basis weight from about 5 to about 20 grams-per-meter-squared (gsm), such as at least about any of the following: 5, 6, 7, 8, 9, 10, 11, and 12 gsm, and/or at most about any of the following: 20, 19, 18, 17, 16, 15, 14, 13, and 12 gsm; and (iii) an absorbent core including (a) a core warp layer and (b) one or more channels defining one or more troughs, wherein the ADL is located directly or indirectly between the topsheet and the core wrap layer of the absorbent core.

An absorbent article comprising a liquid permeable topsheet, a backsheet, an absorbent core comprising an absorbent material and a core wrap is provided. The core comprises at least one channel-forming area that is substantially free of absorbent material. The absorbent article comprises a masking layer between the bottom side of the core wrap and the backsheet. The masking layer and the bottom side of the core wrap are only partially bonded to each other at their interface, the interface thus comprising a bonded portion and an unbonded portion, wherein the channel-forming area at least partially corresponds to the unbonded portion of the interface, so that when the absorbent material swells, the masking layer can decouple from the three-dimensional channels.

An absorbent article that is toxin-free and made from plant-based, biobased, all natural, clean ingredients. In one embodiment, the absorbent article is a diaper made from plant-based resin, comprising: (i) a first layer, wherein the first layer is a cotton top sheet with a wax-based coating deposited on an exterior surface of the first layer (adjacent to the wearer's skin, or user-facing); and (ii) a second layer, wherein the second layer is an acquisition/distribution layer (ADL), and wherein the ADL is comprised of two sub-layers of different materials, a first sublayer comprising an apertured film acquisition sub-layer disposed on top of, and laminated to, a second sub-layer comprising a non-woven acquisition layer.

An absorbent core having a length in a longitudinal direction and a width in a transverse direction, including upper and lower core cover layers and absorbent material sandwiched therebetween, and a pair of channels extending in the longitudinal direction in the absorbent material, each of the channels being free or substantially free from absorbent material and having a channel seal extending therein and joining the core cover layers. For at least one transversal segment of the absorbent core including the channel seals, one core cover layer has a first width between the channel seals, and the other core cover layer has a second width between the channel seals, wherein the first and second widths of the core cover layers are the widths of the core cover layers between the channel seals in an unfolded, flat-out state and wherein the first width is no less than 120% of the second width.
