Abstract: The tensile strength of apertured nonwoven fabric can be increased by a change in the two-stage process of impinging fine columnar streams of liquid, first onto one face of a fibrous web and then onto the opposite face thereof, the change being that the asymmetrical woven wire screen on which the web is positioned during the second stage of the process is oriented with the wire forming the higher knuckle in the screen running in the direction of passage of the web beneath the fine columnar streams, with the area weight of the web being from 0.5 to 2.0 oz/yd.sup.2.
