PURPOSE: To provide the subject nonwoven fabric comprising three-dimensional network fibers in which the three-dimensional network fibers that are made of high-density polyethylene fibrillated fibers are arranged at random, piled up in layers including the independently separable and specific network structure with high opacity and covering power. CONSTITUTION: This nonwoven fabric is constituted of three-dimensional network continuous fibers made of fibrillated high-density polyethylene and they are randomly arranged and laminated. Among the fiber layers, there are at least partially the loosely bonded layers and the partially unfused network fibers can be taken out therefrom independently and the network fiber has the long- period scattering intensity of <=40 according to the X-ray small angle scattering. |
