Реферат: ABSTRACT OF DISCLOSURE An unlayered nonwoven fabric has a uniformly repeating pattern of high fiber density areas, each surrounded by low fiber density areas. The low fiber density areas inconnecting the high fiber density areas are composed of substantially parallelized strands of fibers entering into the high fiber density areas from at least eight directions. These octa-directionally oriented nonwoven fabrics have advantageous tear characteristics, and by the nature of the uniform cover factor of the web, they have many desirable and advantageous uses.
