Abstract

A nonwoven has low tensile and high elongation in the first direction (typically the CD) and high tensile and low elongation in the second direction (typically the MD). The nonwoven has a plurality of bonding points defining a total bonding area along the second direction greater than along the first direction. Accordingly, the nonwoven has unbonded fiber portions and bonded fiber portions, with a bonded portion/unbonded portion ratio greater along the second direction than along the first direction. The bonding points are preferably either circular or oval in plan.
