Multi-layer wiping device

Abstract

A multi-layer article having bonded first and second layers is described herein. The first layer has two plies and a third material disposed therebetween. The two plies are bonded together at a plurality of discrete bond sites. Bonding the plies forms an interior region between the plies. The second layer of the article preferably comprises a cellulosic web.

1 . A multi-layer article comprising a first layer and a second layer bonded to each other; said first layer comprising a first ply, a second ply joined to said first ply in a face-to-face relationship at a plurality of discrete bond sites, said first and second plies forming an interior region therebetween, and a third material being disposed between said first and second plies, said third material being differentiated from said first or second ply by at least one material property selected from the group consisting of thermal properties, elongation properties, elastic properties, conductive properties, and combinations thereof, said third material substantially filling said interior region; and, 
 said third material being apertured in regions coincident with said bond sites, such that said first and second plies are joined through said apertures.

       3 . The multi-layer article of  claim 1  wherein said third material of the said first layer is cellulosic.  
   
   
       4 . The multi-layer article of  claim 3  wherein the first layer and the second layer are joined together at a predetermined pattern of discrete bond sites.  
   
   
       5 . The multi-layer article of  claim 3  wherein the first and second plies of the first layer are further comprised of thermoplastic fibers and the first and second layers are thermally bonded without the addition of an adhesive.  
   
   
       6 . The multi-layer article of  claim 5  wherein the layers are bonded using ultrasonic energy.  
   
   
       7 . The multi-layer article of  claim 1  wherein said bond sites are discrete thermal bonds having an aspect ratio of at least 3:1.  
   
   
       8 . The multi-layer article of  claim 1  wherein said first or second layer comprises a non-woven material.  
   
   
       9 . The multi-layer article of  claim 1  wherein said third material comprises a material selected from the group consisting of cellulosic tissue paper, metal foil, treated materials, polymeric film, open cell foams, pulp, other absorbent materials, polymeric absorbent gelling materials, and combinations thereof.  
   
   
       10 . The multi-layer article of  claim 1  wherein said laminate is extensible.  
   
   
       11 . The multi-layer article of  claim 10  wherein first ply comprises an extensible web having a first elongation to break.  
   
   
       12 . The multi-layer article of  claim 10  wherein said second ply comprises an extensible web joined to said first ply at a plurality of bond sites, said second extensible web having a second elongation to break.  
   
   
       13 . The multi-layer article of  claim 10  wherein said first ply is a first extensible web having a first elongation to break and said second ply is a second extensible web joined to said first extensible web at a plurality of bond sites, said second extensible web having a second elongation to break.  
   
   
       14 . The multi-layer article of  claim 13  wherein said first or second extensible web comprises a non-woven material.  
   
   
       15 . A multi-layer article comprising a first layer and a second layer bonded to each other, said first layer comprising a laminate web having a plurality of apertures, said laminate web comprising first and second extensible webs being joined at a plurality of discrete bond sites, a third material disposed between said first and second extensible webs, and said first and second extensible webs being in fluid communication via said apertures and having distinct regions being differentiated by at least one property selected from the group consisting of basis weight, fiber orientation, thickness, and density.  
   
   
       16 . The multi-layer article of  claim 15  wherein said laminate web is joined by bonds in the absence of adhesive.  
   
   
       17 . The multi-layer article of  claim 15  wherein said first layer further comprises a cellulosic web.  
   
   
       18 . The multi-layer article of  claim 15  wherein said third material comprises a material selected from the group consisting of cellulosic tissue paper, metal foil, treated materials, polymeric film, open cell foams, pulp, other absorbent materials, polymeric absorbent gelling materials, and combinations thereof.  
   
   
       19 . The multi-layer article of  claim 15  wherein said bond sites are discrete thermal bonds having an aspect ratio of at least 10:1.  
   
   
       20 . The multi-layer article of  claim 15  wherein said first or second extensible web comprises a material selected from the group consisting of cellulosic materials, non-woven materials, and combinations thereof.
