ABSTRACT:
A nonwoven fabric having alternating stripes of high fiber density and low fiber density is made in such a manner that the high fiber density stripes run across the fabric and maximize the cross direction strength to a point that the cross direction/machine direction strength ratio approaches unity. This advantageous and desirable characteristic can be achieved by hydroforming a card web, by disposing the carded web on a relatively fine mesh screen and placing a finger-like striping bars over the web with the axis of the bars at 90.degree. to the card web's general fiber orientation. Water was then sprayed over the assembly with sufficient force to rearrange the fibers in the web thereby producing the nonwoven fabric of this invention.
