Tissue products having substantially equal machine direction and cross-machine direction mechanical properties

Abstract

A tissue product having a combination of substantially equal tensile energy absorbed (TEA) in the machine direction and the cross-machine direction of the tissue sheet and a significant level of stretch in both directions provides improved perception of strength and resistance to “poke through” in use.

         7 . The tissue sheet of  claim 1  wherein the geometric mean TEA is about 10 gram-centimeters or less per square centimeter.  
     
     
         8 . The tissue sheet of  claim 1  wherein the geometric mean TEA is from about 2 to about 8 gram-centimeters per square centimeter.  
     
     
         9 . The tissue sheet of  claim 1  wherein the geometric mean TEA is from about 2 to about 4 gram-centimeters per square centimeter.  
     
     
         10 . The tissue sheet of  claim 1  wherein the MD stretch is about 3 percent or greater.  
     
     
         11 . The tissue sheet of  claim 1  wherein the MD stretch is about 5 percent or greater.  
     
     
         12 . The tissue sheet of  claim 1  wherein the MD stretch is from about 3 to about 30 percent.  
     
     
         13 . The tissue sheet of  claim 1  wherein the MD stretch is from about 3 to about 25 percent.  
     
     
         14 . The tissue sheet of  claim 1  wherein the MD stretch is from about 3 to about 15 percent.  
     
     
         15 . The tissue sheet of  claim 1  wherein the MD stretch is from about 3 to about 10 percent.  
     
     
         16 . The tissue sheet of  claim 1  wherein the CD stretch is from about 5 to about 20 percent.  
     
     
         17 . The tissue sheet of  claim 1  wherein the CD stretch is from about 5 to about 15 percent.  
     
     
         18 . The tissue sheet of  claim 1  wherein the CD stretch is from about 5 to about 10 percent.  
     
     
         19 . The tissue sheet of  claim 1  wherein the CD stretch is greater than the MD stretch.  
     
     
         20 . A tissue sheet having a three-dimensional surface topography, an MD/CD TEA ratio of from about 0.8 to about 1.2, a CD stretch of about 5 percent or greater, an MD stretch of about 5 percent or greater and a geometric mean tensile strength of about 1500 grams or less per 3 inches of width.  
     
     
         21 . The tissue sheet of  claim 20  wherein the geometric mean TEA is about 20 gram-centimeter or less per square centimeter.  
     
     
         22 . The tissue sheet of  claim 20  wherein the geometric mean TEA is about 10 gram-centimeter or less per square centimeter.
