Abstract:
A laminate which is elastic in a machine direction and extendible but not elastic in a cross direction, the laminate comprising:a first nonwoven web that is extendible in the cross direction to a stretched width at least 25% greater than an unstretched width upon application of a stretching force, and retractable by zero to not more than 30% of a difference between the stretched and unstretched widths upon relaxation of the stretching force after 60 seconds; and laminated to the nonwoven web, a plurality of elastic members elongatable substantially in the machine direction; wherein the elastic members are bonded in the laminate at a plurality of spaced apart locations when the elastic members are in a stretched condition; to thereby impart elasticity to the laminate in the machine direction without imparting elasticity to the laminate in the cross direction.
