Applications for elastic laminate web

Abstract

An elastic laminate web is disclosed. The elastic laminate web can be nonapertured or apertured, and comprises a first web, and a second web joined to the first web in a face to face relationship at a plurality of discrete bond sites having an aspect ratio of at least 2. The first and second webs form an interior region therebetween. An elastic material is disposed between the first and second webs. The elastic material is apertured in regions coincident the bond sites, such that the first and second webs are joined through the apertures. The laminate so produced can be stretched in a predetermined direction, such as by incremental stretching, to produce an apertured elastic laminate. Also disclosed are mattress covers and other applications in which the elastic laminate web may be used.

What is claimed is:  
     
         1 . A mattress cover comprising a non-apertured elastic laminate web comprising: 
 a) a first web;    b) a second web joined to said first web in a face to face relationship at a plurality of discrete bond sites having an aspect ratio of at least 2, the first and second webs forming an interior region therebetween;    c) an elastic material being disposed between at least a portion of said first and second webs; and    d) said elastic material being apertured in regions coincident said bond sites, such that said first and second webs are joined through said apertures.    
     
     
         2 . The mattress cover of  claim 1 , wherein said laminate is joined by bonds in the absence of adhesive.  
     
     
         3 . The mattress cover of  claim 1 , wherein said bond sites are discrete thermal bonds having an aspect ratio of at least 3:1.  
     
     
         4 . The mattress cover of  claim 1 , wherein said bond sites are discrete thermal bonds having an aspect ratio of at least 10:1.  
     
     
         5 . The mattress cover of  claim 1 , wherein said first or second web comprises a nonwoven.  
     
     
         6 . A mattress cover comprising a laminate web having a plurality of apertures, said laminate web comprising: 
 a) first and second extensible webs being joined at a plurality of discrete bond sites;    b) an elastic material disposed between said first and second nonwoven webs; and    c) the first and second extensible webs being in fluid communication via the apertures.    
     
     
         7 . The mattress cover of  claim 6 , wherein said laminate is joined by bonds in the absence of adhesive.  
     
     
         8 . The mattress cover of  claim 6 , wherein said bond sites are discrete thermal bonds having an aspect ratio of at least 3:1.  
     
     
         9 . The mattress cover of  claim 6 , wherein said bond sites are discrete thermal bonds having an aspect ratio of at least 10:1.  
     
     
         10 . The mattress cover of  claim 6 , wherein said first or second extensible web comprises a nonwoven.
