Abstract
A staple fiber non-woven fabric is provided which comprises, as constituent fibers, first and second split staple fibers composed of first and second fiber formable polymers, respectively, and water-absorptive staple fibers. The first and second split staple fibers have a fineness of not greater than 0.5 denier per fiber. The first and second fiber formable polymers are different polymers selected from the group consisting of a polyamide, a polyester and a polyethylene which are incompatible with each other. The fiber split degree of the first and second split staple fibers is not lower than 85%. The constituent fibers are three-dimensionally entangled with each other.
