Claim 0:
1. A fluid absorbent article, comprising
(A) an upper liquid-pervious sheet;
(B) a lower liquid-impervious sheet;
(C) a fluid-absorbent core comprising from 60 to 20% by weight fibrous material and from 40 to 80% by weight of water-absorbent polymer particles comprising at least a first type of water-absorbent polymer particles (G) and at least a second type of water-absorbent polymer particles (H) based on the sum of water-absorbent polymer particles and fibrous material; and
(D) an optional acquisition-distribution layer (D) between (A) and (C),
wherein the first type of water absorbent polymer particles (G) of the fluid-absorbent core (C) have a SFC of at least 20×10−7 cm3·s/g, and wherein the at least second type of water-absorbent polymer particles (H) of the fluid-absorbent core have a sphericity of at least 0.80,
wherein the first type of water-absorbent polymer particles (G) is present of at least 30% by weight within the fluid-absorbent core (C) and is present of at maximum 70% by weight within the fluid-absorbent core (C) based on the sum of water-absorbent polymer particles (G, H), and
wherein the second type of water-absorbent polymer particles (H) is present of at least 30% by weight within the fluid-absorbent core (C) and is present of at maximum 70% by weight within the fluid-absorbent core (C) based on the sum of water-absorbent polymer particles (G, H).
