Abstract

A laminate includes a core structure having a first surface and a second surface, the core structure including an elastic core layer and a plastic core layer, wherein the elastic core layer is one of a film, a plurality of strands, and a plurality of strips, and wherein the plastic core layer is one of a film layer, a plurality of strands, and a plurality of strips, the plastic core structure reinforcing the core layer in the machine direction, and a nonwoven first facing layer affixed to the first surface.

1 . A laminate comprising:
 a core structure having a first surface and a second surface, the core structure comprising an elastic core layer and a plastic core layer, wherein the elastic core layer is one of a film, a plurality of strands, and a plurality of strips, and wherein the plastic core layer is one of a film layer, a plurality of strands, and a plurality of strips, the plastic core layer reinforcing the core structure in the machine direction; and   a fractured nonwoven first facing layer affixed to the first surface.   
     
     
         2 . The laminate of  claim 1 , wherein the plurality of strands is disposed between the film layer and the first facing layer. 
     
     
         3 . The laminate of  claim 1 , wherein the first facing layer is affixed to the first surface with adhesive. 
     
     
         4 . The laminate of  claim 1 , further comprising a nonwoven second facing layer affixed to the second surface. 
     
     
         5 . The laminate of  claim 1 , wherein the nonwoven first facing layer is cellulose-based. 
     
     
         6 . The laminate of  claim 1 , wherein the nonwoven first facing layer is polymer-based. 
     
     
         7 . The laminate of  claim 1 , wherein the nonwoven first layer includes polymer and cellulose. 
     
     
         8 . The laminate of  claim 1 , wherein the plastic core layer is a film, and wherein the elastic core layer is a plurality of strands or a plurality of strips. 
     
     
         9 . The laminate of  claim 1 , wherein the elastic core layer is a film, and wherein the plastic core layer is a plurality of strands or a plurality of strips. 
     
     
         10 . A method for producing a composite nonwoven elastic web comprising an elastic web joined to a fibrous nonwoven web, the method comprising:
 providing an elastic web comprising a core structure having an elastic core layer and a plastic core layer, wherein the elastic web has a first surface and a second surface;   stretching the elastic web to less than 100 percent stretch;   affixing a fibrous nonwoven web to the first surface of the stretched elastic web to form a composite nonwoven elastic web;   relaxing the composite nonwoven elastic web; and   activating the nonwoven elastic web after affixing the fibrous nonwoven web, thereby fracturing the fibrous nonwoven web.   
     
     
         11 . The method of  claim 10 , wherein activating includes using a groove rolling process or an intermeshing gears process. 
     
     
         12 . The method of  claim 10 , wherein the elastic core layer is one of a film, a plurality of strands, and a plurality of strips, wherein the plastic core layer is one of a film layer, a plurality of strands, and a plurality of strips. 
     
     
         13 . The method of  claim 12 , wherein the elastic core layer is a film, and wherein the plastic core layer is a plurality of strands or a plurality of strips. 
     
     
         14 . The method of  claim 12 , wherein the plastic core layer is a film, and wherein the elastic core layer is a plurality of strands or a plurality of strips. 
     
     
         15 . The method of  claim 10 , wherein the fibrous nonwoven web is affixed to the elastic web with a thermal, adhesive, ultrasonic, or co-extrusion lamination method. 
     
     
         16 . The method of  claim 10 , further comprising affixing a second fibrous nonwoven web to the second surface. 
     
     
         17 . The method of  claim 10 , wherein the fibrous nonwoven web is cellulose-based. 
     
     
         18 . The method of  claim 10 , wherein the fibrous nonwoven web is polymer-based. 
     
     
         19 . The method of  claim 10 , wherein the fibrous nonwoven web includes polymer and cellulose. 
     
     
         20 . A method for producing a composite nonwoven elastic web comprising an elastic web joined to a fibrous nonwoven web, the method comprising:
 providing an elastic web comprising a core structure having an elastic core layer and a plastic core layer, wherein the elastic web has a first surface and a second surface, wherein the elastic core layer is a film, and wherein the plastic core layer is a plurality of strands or a plurality of strips;   stretching the elastic web to less than 100 percent stretch;   affixing a fibrous nonwoven web to the first surface of the stretched elastic web to form a composite nonwoven elastic web, the fibrous nonwoven web including polymeric and/or cellulosic fibers;   relaxing the composite nonwoven elastic web; and   activating the nonwoven elastic web using a groove rolling process or an intermeshing gears process after affixing the fibrous nonwoven web, thereby fracturing the fibrous nonwoven web.
