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.

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.

Disposable wearing articles having a liquid-absorbent structure which is sufficiently thin to ensure a comfortable wear feeling and adapted to eliminate the possibility that the appearance of the absorbing region after absorption of the bodily fluids might be visually recognized from the outside. A liquid-absorbent structure including absorbent materials is attached to a chassis by means of a liquid-absorbent structure bonding region formed on a skin-facing side. The liquid-absorbent structure bonding region includes opposite end bonding zones serving to fix first and second end segments of the liquid-absorbent structure and opposite lateral bonding zones serving to fix opposite lateral segments of the liquid-absorbent structure and a central non-bonding region is defined by a region surrounded by the opposite end bonding zones and the opposite lateral bonding zones.

An absorbent sanitary pad with side flaps having a higher basis weight of superabsorbent polymer in correspondence with the wings end points which helps reducing side leakage.

An folded absorbent sanitary pad having a lower basis weight of superabsorbent polymer in correspondence with the folding lines which helps reducing the stiffness of the article caused by the folding lines.

An article including: an absorbent body including two liquid-permeable non-woven fabric sheets bonded together at bonded portions in a predetermined pattern, and a plurality of granular particles placed therebetween separately in each of a plurality of placement areas partitioned from one another in the predetermined pattern; and a non-liquid-permeable back sheet placed on a non-skin-contact surface of the absorbent body, wherein: a liquid-permeable sheet is placed so as to cover an entire surface of the non-woven fabric sheet on a skin-contact surface side; and an easily-breakable portion capable of being broken when the granular particles absorb a bodily fluid to swell is formed in placement areas on at least one non-woven fabric sheet.

An absorbent article having an absorbent core having a longitudinally extending channel-forming area and a wetness indicator is presented. The core wrap has a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid a channel is formed along the area substantially free of absorbent material.

An absorbent article includes a front waist edge, a rear waist edge longitudinally opposing the front waist edge, and a longitudinal axis extending from a midpoint of the front waist edge to a midpoint of the rear waist edge. The absorbent article comprises a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed at least partially intermediate the topsheet and the backsheet. The absorbent core comprises a first continuous channel and a second continuous channel, each substantially free of the superabsorbent polymers and at least partially oriented in the longitudinal direction of the absorbent. The first and second channels each have lateral widths parallel to the lateral axis. A profile of the lateral widths of each channel over a longitudinal length of at least 50 mm of the channel taken along the longitudinal axis is substantially constant. The average lateral width of the first channel differs from an average lateral width of the second channel.

An absorbent system including a first absorbent core layer, the first absorbent core layer made up of cellulose and superabsorbent material, a second absorbent core layer disposed above the first absorbent core layer, the second absorbent core layer made up of synthetic material and superabsorbent material, the second absorbent layer having end portions that are folded so that the second absorbent layer has a C-shape, a first acquisition-distribution layer disposed over the second absorbent core layer, a core wrap disposed around the first absorbent core layer, the second absorbent core layer, and the first acquisition-distribution layer, and a second acquisition-distribution layer disposed over the core wrap.

An absorbent core, for use in an absorbent article, including a core wrap enclosing an absorbent material and including superabsorbent polymer particles. The core wrap includes a top side and a bottom side, and the absorbent core includes 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 time to reach an uptake of 20 g/g (T20) of less than 240 s as measured according to the K(t) test method.
