PROBLEM TO BE SOLVED: To obtain a nonwoven fabric not dropping water-absorbing fibers on its production and excellent in water absorbency, absorbed water holdability and repeated washing resistance by including the water-absorbing staple fibers in a prescribed amount and controlling an absorbed water-holding rate to a prescribed value or larger. SOLUTION: This water-absorbing nonwoven fabric contains water-absorbing staple fibers comprising a polyacrylic acid alkali metal salt, etc., in an amount of 5-60 wt.%, and has an absorbed water-holding rate of >=60% after washed ten times. The water-absorbing staple fibers preferably have a gel strength of >=400 g/cm<2> in a water-absorbed state. |
