Outline of Final Research Achievements

A basic research was carried out for development of the high-performance diaper material with deodorizing abilities. Poly(vinyl alcohol) (PVA) was chosen as a model material of diaper, and the membrane and cylindrical PVA hydrogels were prepared. Sorption for simple salts was examined by using the PVA gel membranes, and the relation between the salt sorption behavior and the state of the water in the membranes was discussed. Cotton fabrics were mordant-dyed with direct dyes and a copper salt, and the kinetics of the deodorization by the obtained mordant-dyed fabrics was investigated. The interaction between copper ions and PVA, which gives the deodorizing function to PVA gels, was examined on the basis of the results for the swelling degrees of the cylindrical PVA gels in the aqueous solutions of copper salts.
