摘要：
A nonwoven (10) having a low tensile strength and high elongation in the first direction (typically the CD (12)) and high tensile strength and low elongation in the second direction (typically the MD (14)). The nonwoven (10) has a plurality of bonding points (20) defining a total bonding area along the second direction (14) greater than along the first direction (12). Accordingly, the nonwoven has unbonded fiber portions (30) and bonded fiber portions (32), with a bonded portion/unbonded portion ratio greater along the second direction (14) than along the first direction (12). The bonding points (20) are preferably either circular (22) or oval (24) in plan.
