Abstract:
A method for manufacturing a fabric containing superabsorbers, comprising the steps ofa) mixing a cross-linkable superabsorber polymer with a solvent to form a superabsorber polymer solution which can be separated into phases, and impregnating the polymer fibers with this solution,b) inducing a phase separation of the superabsorber polymer solution into a phase containing fibers and enriched with polymer, and a phase depleted of polymer,c) during the phase separation, cross-linking the superabsorber polymer in the polymer-enriched phase containing fibers, to form a microporous, open-celled foam on the fibers, andd) drying the resulting body containing superabsorber polymer while maintaining the microporous, open-celled structure in the superabsorber polymer.
