COMPOSITE MATERIAL FOR ABSORBENT ARTICLE, AND METHOD FOR MANUFACTURING SAID MATERIAL

摘要

A composite material for an absorbent article and a method for manufacturing said composite material, said composite material being obtained by causing an absorbent material to adhere by electrostatic interaction to a substrate material, the surface of the absorbent material being positively or negatively charged in a prescribed solvent selected from among a nonpolar organic solvent, a polar organic solvent, and a water/polar organic solvent mixture; and the surface of the composite material being charged to an electrical charge opposite to that of the surface of the substrate material, in the prescribed solvent. The substrate material has a fiber substrate or a plastic substrate, and a polyelectrolyte layer provided on the surface layer; and/or the absorbent material has an absorbent-particle substrate or an absorbent fiber substrate, and a polyelectrolyte layer provided on the surface layer.

1. A composite material for an absorbent article, comprising a substrate material having a surface which is positively or negatively electrostatically charged in a predetermined solvent selected from a non-polar organic solvent, a polar organic solvent, and a mixed solvent of a polar organic solvent and water, and a water absorbent material adsorbed thereon by electrostatic interaction, having a surface which is electrostatically charged to an electric charge opposite to that of the surface of the substrate material,
wherein the substrate material comprises a fibrous base material or resinous base material and a polyelectrolyte layer provided in a surface layer thereof, and/or, the water absorbent material has a water absorbent particulate base material or water absorbent fibrous base material and a polyelectrolyte layer provided in a surface layer thereof.
