Abstract

A nonwoven fabric from spun fibers wherein the density of the spun fibers in the fabric varies between strips of relatively high density and strips of relatively low density. The strips extend along the length of the fabric in the machine direction in an alternating pattern, with the high density strips separated from each other by low density strips. The alternating high density and low density strips provide the fabric with a higher percent elongation in the cross direction than in the machine direction. The alternating pattern is achieved through use of a pattern screen defining a plurality of elongated air permeable regions separated by elongated substantially or relatively air impermeable regions, the elongated regions extending in the machine direction in an alternating pattern, with the air permeable regions separated from each other by the substantially or relatively air impermeable regions.
