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.
