Web material structuring belt, method for making and method for using

Abstract

Web material structuring belts that impart structure to a web material during a web material structuring operation and/or structured web material forming operation, method for making same and methods for using same to make structured web materials, for example structured fibrous structures, such as structured sanitary tissue products such as structured toilet tissue, structured paper towels and structured facial tissue are provided.

What is claimed is: 
     
         1 . A method for making a web material structuring belt, the method comprising the steps of:
 a. providing a support layer that exhibits an air perm of greater than 300 scfm; and   b. providing a structuring layer associated with the support layer such that the structuring layer extends at least 5% into the support layer, but less than entirely through the support layer;   wherein a first portion of the structuring layer that extends into the support layer is bonded to the support layer at one or more bond sites, and wherein a second portion of the structuring layer that extends into the support layer is unbonded; and   wherein the association between the support layer and the structuring layer exhibits a Peak Peel Force value of greater than 0.1 N.   
     
     
         2 . The method according to  claim 1 , wherein the support layer comprises a woven fabric. 
     
     
         3 . The method according to  claim 1 , wherein the structuring layer comprises a pattern. 
     
     
         4 . The method according to  claim 1 , wherein the structuring layer comprises a polymer. 
     
     
         5 . The method according to  claim 1 , wherein the structuring layer comprises a film. 
     
     
         6 . The method according to  claim 1 , wherein the structuring layer comprises a resin. 
     
     
         7 . The method according to  claim 1 , wherein the associating layer is mechanically entangled with the support layer. 
     
     
         8 . The method according to  claim 1 , wherein at least a portion of the associating layer that extends into the support layer is bonded to the support layer at one or more bond sites. 
     
     
         9 . The method according to  claim 1 , wherein the web material structuring belt exhibits a Peak Peel Force value of greater than 0.1 N as measured according to the 180° Free Peel Test Method. 
     
     
         10 . The method according to  claim 1 , wherein the web material structuring belt exhibits an Energy value of greater than 0.1 J/m as measured according to the 180° Free Peel Test Method. 
     
     
         11 . A method for making a web material structuring belt, the method comprising the steps of:
 a. providing a support layer that exhibits an air perm of greater than 300 scfm, the support layer comprising a woven portion;   b. providing a structuring layer;   c. associating the structuring layer with the support layer such that the structuring layer extends into the support layer by at least 100 microns, but less than entirely through the support layer; and   d. penetrating the woven portion of the support layer with the structuring layer;   wherein a first portion of the structuring layer that extends into the support layer is bonded to the support layer at one or more bond sites, and wherein a second portion of the structuring layer that extends into the support layer is unbonded; and   wherein the association between the support layer and the structuring layer exhibits a Peak Peel Force value of greater than 0.1 N.   
     
     
         12 . A method for making a web material structuring belt, the method comprising the steps of:
 a. providing a support layer that exhibits an air perm of greater than 300 scfm;   b. forming a structuring layer on the support layer such that the structuring layer extends into the support layer by at least 100 microns, but less than entirely through the support layer;   wherein a first portion of the structuring layer that extends into the support layer is bonded to the support layer at one or more bond sites, and wherein a second portion of the structuring layer that extends into the support layer is unbonded; and   wherein an association between the support layer and the structuring layer exhibits a Peak Peel Force value of greater than 0.1 N.   
     
     
         13 . A method for making a web material structuring belt, the method comprising the steps of:
 a. providing a structuring layer that exhibits an air perm of greater than 300 scfm; and   b. forming a support layer on the structuring layer such that the structuring layer extends greater than about 1 filament into the support layer, but less than entirely through the support layer;   wherein a first portion of the structuring layer that extends into the support layer is bonded to the support layer at one or more bond sites, and wherein a second portion of the structuring layer that extends into the support layer is unbonded; and   wherein an association between the support layer and the structuring layer exhibits a Peak Peel Force value of greater than 0.1 N.
