IMPROVED NONWOVEN WITH NON-SYMMETRICAL BONDING CONFIGURATION

摘要

A nonwoven (10) having a low tensile strength and high elongation in the fir st 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 bond- ing 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.
