Abstract
The present invention provides a stable nonwoven web having enhanced extensibility and a method for making the same. A neckable nonwoven web is fed in a first direction. The neckable nonwoven web is subjected to incremental stretching in a direction perpendicular to the first direction. A tensioning force is applied to the neckable nonwoven web to neck the nonwoven web. The necked nonwoven web is then subjected to mechanical stabilization to provide a stabilized extensible necked nonwoven web. The stabilized extensible necked nonwoven web is easily extended in a direction parallel to the direction necking.
