Fundamental research on the development of diaper material with deodorizing ability was carried out. As models of water-absorbent materials, polymer gels were prepared from water-soluble synthetic polymers. The degree of swelling for the obtained polymer gels was measured in aqueous solutions of dyes, carboxylic acids and sodium carboxylates. Sorption of direct dyes for the gels and swelling behavior of the gels in aqueous direct dye solutions were also investigated. The possibility for preparation of diaper with deodorizing function was examined.
