Title:

ABSORBENT SHEET AND ABSORBENT ARTICLE

Document Type and Number:

WIPO Patent Application WO/2018/116849

Kind Code:

A1

Abstract:

This absorbent article (20) is provided with: an absorbent sheet (10) which is obtained by affixing a water absorbent polymer (12) to a substrate sheet (11); and a cover sheet (21) which covers at least one surface of the absorbent sheet (10). The absorbent sheet (10) has a water absorbent polymer fixation rate of 40% or more. Since this absorbent article (20) exhibits high fixation performance of the water absorbent polymer (12) to the substrate sheet (11), falling-off of the water absorbent polymer (12) is not likely to occur even after absorption of a liquid. The water absorbent polymer (12) is preferably affixed to the substrate sheet (11), with an adhesive (13) for substrate sheet fixation being interposed therebetween. The adhesive (13) is preferably an acrylic, silicone-based or rubber-based adhesive, and is preferably a hot melt adhesive.
