WATER-ABSORBENT ARTICLE

摘要

Water-absorbent articles improved to alleviate an uncomfortable feeling due to water-soluble matter contained in superabsorbent polymer particles are provided. In an absorbent article (1) adapted to be used, for example, as an absorbent structure in a disposable diaper, superabsorbent polymer particles (4) are interposed between opposed surfaces (2a, 3a) of a pair of sheet materials (2, 3) overlapping each other. The superabsorbent polymer particles (4) used in this invention has a water-soluble matter content percentage corresponding to 15% or less of a mass of the superabsorbent polymer particles (4) as measured by immersing them in 0.9% physiological saline.
