Abstract:
1. A nonwoven fabric, containing ultra-fine fibers and does not contain an elastomer, which contains staple fibers with a fiber fineness of 0.0001 to 0.5 decitex and a fiber length of 2 cm to 10 cm and at least substantially all of the ultra-fine fibers are uniformly entangled with each other such that there is substantially no entanglement between bundles of ultra-fine fibers in the thickness direction, and has a weight per unit area of 100 to 550 g/m 2 , an apparent density of 0.280 to 0.700 g/cm 3 , a tensile strength of 70 N/cm or more, a 10% modulus in the length direction is 8 N/cm or more and a tear strength of 3 to 50 N.
