Abstract
A nonwoven fabric comprising extendable fiber and elastic fiber, wherein the nonwoven fabric comprises a first side having a plurality of protrusions and a plurality of recesses and a second side on the side opposite the first side, the proportion of extendable fiber in the protrusions on the first side is higher than the proportion of extendable fiber in the recesses on the first side, and the nonwoven fabric is coated with a hydrophilic agent, or the extendable fiber and elastic fiber comprise a hydrophilic agent, the nonwoven fabric has a water absorbing property represented by a water absorption height of at least 10 mm in a water absorption test, and a quick-drying property represented by a transpiration rate of at least 20 mass % in a transpiration test.
