This invention relates to a process for producing water-absorbing composites comprising the steps of foaming an aqueous mixture comprising at least one monoethylenically unsaturated monomer bearing acid groups, at least one crosslinker, at least one initiator and at least one surfactant, contacting the foam obtained with at least one web of synthetic fibers and polymerizing, to the composites themselves and to their use for absorbing aqueous fluids.

Water-absorbing composites

A hydrogel having a floatability where from 40% to 90% of a solution and/or suspension to be thickened are thickened starting from the surface of the liquid and the rest of the solution and/or suspension to be thickened is thickened starting from the bottom of the container, a process for preparing the hydrogel and also its use for absorbing blood and/or body fluids, especially in hygiene articles, or for thickening aqueous solutions and/or suspensions, especially for thickening medical wastes.
