Abstract

A method of making tissue sheets is disclosed in which three-dimensional woven papermaking fabrics, such as throughdrying fabrics, are provided with woven highlight areas, particularly woven highlight areas containing design elements which make the design elements more visible in the resulting tissue product.

Claims

exact text as granted — not AI-modified
1 . A method of making a tissue sheet comprising: 
 (a) depositing an aqueous suspension of papermaking fibers onto a forming fabric, thereby forming a wet tissue web;    (b) transferring the wet tissue web to a woven papermaking fabric having a textured background sheet-contacting surface containing a woven highlight area surrounding a design element; and    (c) drying the wet tissue web.    
   
   
       2 . The method of  claim 1  wherein the shape of the highlight area is substantially the same as the periphery of the design element.  
   
   
       3 . The method of  claim 1  wherein the shape of the highlight area is substantially different than the shape of the periphery of the design element.  
   
   
       4 . The method of  claim 1  wherein the area of the highlight area is from about 125 to about 600 percent of the area of the design element.  
   
   
       5 . The method of  claim 1  wherein the design element comprises an extruded material on top of the highlight area.  
   
   
       6 . The method of  claim 1  wherein the design element is raised above the surface plane of the highlight area.  
   
   
       7 . The method of  claim 1  wherein the design element is depressed below the surface plane of the highlight area.  
   
   
       8 . The method of  claim 1  wherein the design element is air-permeable.  
   
   
       9 . The method of  claim 1  wherein the design element is higher than the surface plane of the textured background surface.  
   
   
       10 . The method of  claim 1  wherein the woven highlight area is overlaid with a foam material and the design element comprises an extruded material on top of the foam material.  
   
   
       11 . The method of  claim 10  wherein the woven highlight area is overlaid with a foam material and the design element is recessed within the foam material.  
   
   
       12 . A method of making a tissue sheet comprising: 
 (a) depositing an aqueous suspension of papermaking fibers onto a forming fabric, thereby forming a wet tissue web;    (b) transferring the wet tissue web to a woven papermaking fabric having a textured background sheet-contacting surface containing a woven highlight area; and    (c) drying the wet tissue web.    
   
   
       13 . The method of  claim 1  or  12  wherein the highlight area is textured.  
   
   
       14 . The method of  claim 1  or  12  wherein the highlight area is substantially flat.  
   
   
       15 . The method of  claim 1  or  12  wherein the shape of the highlight area is substantially circular.  
   
   
       16 . The method of  claim 1  or  12  wherein the shape of the highlight area is substantially rhomboid.  
   
   
       17 . The method of  claim 1  or  12  having a plurality of highlight areas wherein the center-to-center spacing of the highlight areas is from about 1 to about 6 inches.  
   
   
       18 . The method of  claim 1  or  12  wherein the area of the highlight area is about 3 square centimeters or greater.  
   
   
       19 . The method of  claim 1  or  12  wherein the highlight area is air-permeable.  
   
   
       20 . The method of  claim 1  or  12  wherein the surface plane of the highlight area is higher than the surface plane of the textured background surface.  
   
   
       21 . The method of  claim 1  or  12  wherein the highlight area is overlaid with an air-permeable open-cell foam material.  
   
   
       22 . A tissue sheet made by the method of  claim 1  or  12 .  
   
   
       23 . A method of forming an air-laid web comprising depositing a pneumatic suspension of fibers onto a woven papermaking fabric having a textured background surface containing a woven highlight area.  
   
   
       24 . The method of  claim 23  wherein the woven highlight area contains a design element.  
   
   
       25 . A woven papermaking fabric having a textured background sheet-contacting surface containing a woven highlight area.  
   
   
       26 . The fabric of  claim 25  wherein the woven highlight area further contains a design element.  
   
   
       27 . The fabric of  claim 26  wherein the shape of the highlight area is substantially the same as the periphery of the design element.  
   
   
       28 . The fabric of  claim 26  wherein the shape of the highlight area is substantially different than the shape of the periphery of the design element.  
   
   
       29 . The fabric of  claim 26  wherein the area of the highlight area is from about 125 to about 600 percent of the area of the design element.  
   
   
       30 . The fabric of  claim 26  wherein the design element comprises an extruded material on top of the highlight area.  
   
   
       31 . The fabric of  claim 26  wherein the design element is raised above the surface plane of the highlight area.  
   
   
       32 . The fabric of  claim 26  wherein the design element is depressed below the surface plane of the highlight area.  
   
   
       33 . The fabric of  claim 26  wherein the design element is air-permeable.  
   
   
       34 . The fabric of  claim 26  wherein the design element is higher than the surface plane of the textured background surface.  
   
   
       35 . The fabric of  claim 26  wherein the woven highlight area is overlaid with a foam material and the design element comprises an extruded material on top of the foam material.  
   
   
       36 . The fabric of  claim 26  wherein the woven highlight area is overlaid with a foam material and the design element is recessed within the foam material.  
   
   
       37 . The fabric of  claim 25  or  26  wherein the highlight area is textured.  
   
   
       38 . The fabric of  claim 25  or  26  wherein the highlight area is substantially flat.  
   
   
       39 . The fabric of  claim 25  or  26  wherein the shape of the highlight area is substantially circular.  
   
   
       40 . The fabric of  claim 25  or  26  wherein the shape of the highlight area is substantially rhomboid.
