Abstract: An absorbent article comprises a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core positioned at least partially intermediate the topsheet and the backsheet, and a distribution material comprising a wet-laid, three-dimensional fibrous substrate comprising at least 80% pulp fibers by weight of the wet-laid, three-dimensional fibrous substrate. The wet-laid, three-dimensional fibrous substrate comprises a continuous network region and a plurality of discrete zones. The discrete zones are dispersed throughout the continuous network region. The continuous network region and the plurality of discrete zones have a common intensive property. The common intensive property of the continuous network region has a first value. The common intensive property of the plurality of discrete zones has a second value. The first value is different than the second value.

Abstract: A method for determining the time dependent effective permeability and the uptake kinetics of hydrogel-forming superabsorbent polymer particles under pressure.

Abstract: 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.

Abstract: An folded absorbent sanitary pad having a higher basis weight of superabsorbent polymer in correspondence with the folding lines which helps reducing the risk of side leakage.

Abstract: 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.

Abstract: An absorbent core structure for disposable absorbent articles, having improved fluid handling properties

Abstract: An absorbent article such as disposable diaper, training pant, and adult incontinence undergarment comprising an absorbent structure comprising superabsorbent polymer particles, the article being able to absorb and contain body exudates and having improved absorption properties and therefore being able to reduce leakage, especially at the first gush, i.e. when the article starts to be wetted.

Abstract: An absorbent core (28), for use in an absorbent article, comprising a core wrap (16, 16?) enclosing an absorbent material (60) comprising superabsorbent polymer particles. The core wrap comprises a top side (16) and a bottom side (16?), and the absorbent core comprises one or more area(s) (26) 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) (26?) along the area(s) (26) 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.

Abstract: Process for the biological treatment of organic wastes, includes a first anaerobic digestion phase and a second aerobic digestion phase in succession, a respective filtration phase of the solid substance being provided between the two digestion phases, a separation phase of the biogas released in the anaerobic digestion phase and a nitrogen recovery phase from the exhaust gases rich in ammoniac substances separated from the aerobic digestion phase. The solid substance coming from each of the filtration phases is separately returned to the respective digestion phase, while the liquid phase coming from the filtration phase downstream of the anaerobic digestion phase is sent to aerobic phase. In the nitrogen recovery phase the gaseous current consisting of exhaust gases rich in ammoniac substances is treated with a solution of carbonic acid supplied in countercurrent in a first gas/liquid contactor to obtain a mixture of nitrogen salts (ammonium bicarbonate, ammonium carbonate, etc.).

Abstract: A method for designing an absorbent article and evaluating its absorption behaviour is disclosed. A system using the method, is also disclosed. The method may be used for analyzing movement of a fluid in an absorbent article that comprises fluid-swellable composite material, to determine the performance of at least one feature of the absorbent article. The method includes inputting one or more properties for said fluid-swellable composite material into a virtual model of the absorbent article to produce a representation of at least one feature of the absorbent article and evaluating the virtual model of the absorbent article to determine the performance of the feature.
