PROBLEM TO BE SOLVED: To provide a compounded material for absorptive articles, in which a substrate material is compounded with a water absorptive material without depending on an adhesive, without being heated and without immersing the water absorptive material in the substrate material.SOLUTION: The compounded material for absorptive articles is obtained by attracting the water absorptive material, the surface of which is electrified to have the charge opposite to that of the surface of the substrate material in a predetermined solvent selected from nonpolar organic solvents, polar organic solvents and mixed solvents of polar organic solvents with water, to the substrate material, the surface of which is electrified to have the positive or negative charge in the predetermined solvent, by electrostatic interaction. The substrate material has a fiber substrate or a resin substrate and a polymer electrolyte layer arranged on the surface layer thereof and/or the water absorptive material has a water-absorptive particle substrate or a water-absorptive fiber substrate and another polymer electrolyte layer arranged on the surface layer thereof. |
