To obtain a hydrolyzable liquid retaining material having excellent performances such as liquid retaining properties, strength, softness and efficiently disposable, and a sanitary material and a liquid retaining body suitable as a material for constituting the hydrolyzable liquid retaining material.
The hydrolyzable liquid retaining material is obtained by using a dry nonwoven fabric having ≤0.5 g/cm3 density constituted of a fiber having ≤10 dtex fineness. The fiber constituting the dry nonwoven fabric in an amount of 10-90 mass % is a polyvinyl alcohol-based water-soluble fiber having ≤40°C dissolution temperature in water, and the nonwoven fabric is covered with a hydrolyzable material to give the objective hydrolyzable liquid retaining material.
