The thickness of the nonwoven fabric when wet is greater than or equal to 85% the thickness of the nonwoven fabric when dry. The nonwoven fabric includes a first fiber layer and a second fiber layer. The first fiber layer is constituted by durable hydrophilic fibers, and the second fiber layer is constituted by durable hydrophilic fibers and non-durable hydrophilic fibers.
