Patent ID: 8796174

Claim:
A process for preparing a fluid-absorbent core, comprising (i) mixing of a fibrous material and 10 to 95% by weight of fluid-absorbent polymer particles having a particle size of less than 1000 μm, a median particle size of 200 to 600 μm, a moisture content of at least 8% by weight and less than 20% by weight, a mean sphericity of at least 0.84 and a floating particle fraction (FPF) of at least 10%, and (ii) pressing the obtained mixture, wherein the pressing (ii) is performed that the core (C) has a density of 1 ·D<β× 0.14 g/cm 3 +0.18 g/cm 3 wherein D is the density of the core (C) and β is the weight fraction of fluid-absorbent polymer particles in the core (C).
