(57) [Summary]nThe present invention relates to such fibers that have been treated to enhance the permeability of absorbent structures prepared from the fibers. Furthermore, the present invention relates to a fiber treated with a polyvalent metal ion-containing compound for use in an absorbent structure composed of such fibers, and an absorbent product comprising such an absorbent structure. In particular, the present invention provides an absorbent structure comprising fibers combined with a polyvalent cation-containing compound exhibiting an ion extraction factor of at least 5% and superabsorbent polymer particles, said fibers comprising at least 25 Wherein the polyvalent cation is present in an amount of more than 0.25% to 5% by weight of the fiber and consists of transition metal ions, in particular aluminum, iron, tin and mixtures thereof Selected from. |
