Abstract: Described herein is a fluid-absorbent core including at least two layers, an upper layer and a lower layer, each layer including from 0 to 10% by weight fibrous material and from 90 to 100% by weight water-absorbent polymer particles, based on the sum of water-absorbent polymer particles and fibrous material, where within the upper layer (91) is a water absorbent mixture including at least 10% by weight of a first type of water-absorbent polymer particles, water-absorbent polymer particles G, with a vortex of less than 30 s and at least 50% by weight of a second type of water-absorbent polymer particles, water-absorbent polymer particles H, with a CRC of at least 25 g/g. Also described herein is a fluid-absorbent article including the fluid-absorbent core.

Abstract: A fluid-absorbent article having an upper liquid-pervious layer, a lower liquid-impervious layer, a fluid-absorbent core between the layer and the layer, containing from 0 to 20% by weight fibrous material and from 80 to 100% by weight of a water-absorbent polymer material, based on the sum of water-absorbent polymer material and fibrous material. The fluid absorbent article has a first intake time of 15 seconds or less by the hanging U-shape test (HUS).

Abstract: Described herein is a feminine hygiene absorbent article, including: (A) an upper liquid-pervious layer, (B) a lower liquid-impervious layer, (C) a fluid-absorbent core between the layer (A) and the layer (B), including 5% to 50% by weight of water-absorbent polymer particles G and not more than 95% by weight of fibrous material, based on the sum of water-absorbent polymer particles G and fibrous material; (D) an optional acquisition-distribution layer between (A) and (C), (E) an optional tissue layer disposed immediately above and/or below (C); and (F) other optional components, where the water-absorbent polymer particles G are obtainable by agglomerating a blend of non-surface post-crosslinked fine water-absorbent polymer particles and surface post-crosslinked fine water-absorbent polymer particles, and drying, grinding, sieving and classifying the agglomerated water-absorbent polymer particles.
