Provided is an absorbent article that has an excellent capability of quickly absorbing a large amount of urine and the like, while preventing loss of the absorbing polymers to the outside of the absorbent article where the absorbent article comprises a first nonwoven fabric and a second nonwoven fabric between which a water-absorbing polymer group is placed, in which the surface of the first nonwoven fabric on the side of the water-absorbing polymer group has openings.

The present invention generally relates to a diaper core, specifically a triple leak guard diaper core (1) for infant and adult, comprising: a center core (10) comprising liquid absorbing material (12) and a plurality of hollow sections (14) disposed on the core (10) longitudinally, allowing the core (10) to bend upward or forming a U-channel, and a center core top surface (CCTS) is provided facing a liquid discharge source (16); at least one layer of bottom core wrap (16) encapsulates the center core (10) with a bottom core gap (BCG) disposed on the center core top surface (CCTS); at least one layer of top core wrap (18) is disposed on the bottom core gap (BCG) and the bottom core wrap (16); and at least one layer of acquisition distribution layer (20) is disposed on the top core wrap (18).

An absorbent core for use in an absorbent article is provided and comprises a core wrap enclosing an absorbent material, the absorbent material comprising superabsorbent polymer particles. The core wrap comprises a top side and a bottom side. The absorbent core comprises one or more area(s) substantially free of absorbent material through which the top side of the core wrap is attached to the bottom side of the core wrap (i.e. core wrap bond(s)), so that when the absorbent material swells, the core wrap forms one or more channel(s) along the area(s) substantially free of absorbent material. The superabsorbent polymer particles have a value of Effective Capacity (EFFC) of at least 27 g/g. The Effective Capacity (EFFC) is calculated via the formula below: EFFC=(CRC+AAP)/2. The Centrifuge Retention Capacity (CRC) is measured according to the Centrifuge Retention Capacity (CRC) test method and the Absorption Against Pressure (AAP) is measured according to the Absorption Against Pressure (AAP) test method. The superabsorbent polymer particles have a bulk density of at least 0.5 g/ml according to the Bulk Density Test Method.

An absorbent core for use in an absorbent article is provided and comprises a core wrap enclosing an absorbent material, the absorbent material comprising superabsorbent polymer particles. The superabsorbent polymer particles represent less than 85% by weight based on the total weight of the absorbent material. The core wrap comprises a top side and a bottom side, the absorbent core comprises one or more area(s) substantially free of absorbent material through which the top side of the core wrap is attached to the bottom side of the core wrap, so that when the absorbent material swells the core wrap forms one or more channel(s) along the area(s) substantially free of absorbent material. The superabsorbent polymer particles have a value of Absorption Against Pressure (AAP) of at least 22 g/g according to the Absorption Against Pressure Test Method and a bulk density of at least 0.5 g/ml according to the Bulk Density Test Method.

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.
