Abstract: 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.

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: The present invention relates to agglomerated superabsorbent polymer particles which have been agglomerated by using a multivalent salt having a valence of three or higher. Due to agglomeration, the mean average particle size increase by at least 25% compared to the mean average particle size of the non-agglomerates superabsorbent polymer particles.
