摘要：
Provided herein are fluid-absorbent articles, fluid absorbent cores, and fluid-absorbent mixtures with improved properties, especially rewet performance and liquid acquisition. The fluid-absorbent article includes (A) an upper liquid-pervious sheet, (B) a lower liquid-impervious sheet, (C) a fluid-absorbent core including from 60 to 20% by weight fibrous material and from 40 to 80% by weight of 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, (D) an optional acquisition-distribution layer (D) between (A) and (C), (F) other optional components, 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.
