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.
Claims16
An elastic laminate comprising:
- an elongatable nonwoven web necked in a first direction which recovers less than about 55 percent of its elongation upon release of an elongation force applied to said web in a direction parallel to said first direction;
- and
- an elastic member joined to the elongatable, necked nonwoven web while the nonwoven web is in a substantially untensioned condition.
An elastic laminate comprising:
- an incrementally stretched, elongatable, necked nonwoven web;
- and
- an elastic member joined to the incrementally stretched, elongatable, necked nonwoven web, the nonwoven web and elastic member being joined while the elastic member is in a substantially untensioned condition.
