High Basis Weight Tissue with Low Slough

Abstract

Low slough, high basis weight tissue webs and products are provided. The tissue webs generally have basis weights greater than about 16 grams per square meter (gsm), while maintaining less than about 4 mg of slough. All while yielding tissue products that are both thick and soft.

We claim: 
     
         1 . A creped tissue product comprising two or more tissue webs, wherein the basis weight of each web is greater than about 16.5 gsm the product having a slough less than about 4 mg and a geometric mean tensile less than about 1000 g/3″. 
     
     
         2 . The creped tissue product of  claim 1 , wherein the basis weight of each web is from about 16.5 to about 20 gsm. 
     
     
         3 . The creped tissue product of  claim 1 , wherein the geometric mean tensile of each web is from about 300 to about 500 g/3″. 
     
     
         4 . The creped tissue product of  claim 1  wherein the geometric mean tensile of the product is from about 600 to about 1000 g/3″. 
     
     
         5 . The creped tissue product of  claim 1  wherein the slough is from about 2 to about 5 mg. 
     
     
         6 . The creped tissue product of  claim 1  wherein the two or more tissue webs comprise a blend of hardwood fibers and softwood fibers, the hardwood fibers comprising at least about 60 percent and the softwood fibers comprising less than about 40 percent of the total weight of the web. 
     
     
         7 . The creped tissue product of  claim 1  wherein the two or more tissue webs comprise an inner layer and at least one outer layer contiguous with the inner layer. 
     
     
         8 . The creped tissue product of  claim 6  wherein the two or more tissue webs comprise an inner layer disposed between two outer layers. 
     
     
         9 . The creped tissue product of  claim 7  wherein the inner layer comprises softwood fibers and the outer layers comprise hardwood fibers. 
     
     
         10 . A multi-ply tissue product comprising two multi-layered creped tissue webs, the tissue webs having three superposed layers, an inner layer consisting essentially of softwood fibers and two outer layers consisting essentially of hardwood fibers, the inner layer being located between the two outer layers, wherein each web has a geometric mean tensile of less than about 500 g/3″, a basis weight of at least about 16.5 gsm and a slough of less than about 4 mg. 
     
     
         11 . The creped tissue product of  claim 10 , wherein the basis weight of the product is from about 33 to about 42 gsm. 
     
     
         12 . The creped tissue product of  claim 10 , wherein the geometric mean tensile of the product is from about 600 to about 1000 g/3″. 
     
     
         13 . The creped tissue product of  claim 10 , wherein the slough of each web is from about 2 mg to about 5 mg. 
     
     
         14 . A creped tissue web having a first side and a second side and a creping composition comprising a non-fibrous olefin polymer disposed on at least the first side, wherein the tissue web has a geometric mean tensile of less than about 500 g/3″, a basis weight of at least about 16.5 gsm and a slough of less than about 4 mg. 
     
     
         15 . The creped tissue web of  claim 14 , wherein the basis weight of the web is from about 16.5 to about 20 gsm. 
     
     
         16 . The creped tissue web of  claim 14 , wherein the geometric mean tensile of the web is from about 300 to about 500 g/3″. 
     
     
         17 . The creped tissue web of  claim 14 , wherein the slough is from about 2 to about 5 mg. 
     
     
         18 . The creped tissue web of  claim 14 , wherein the web comprises a blend of hardwood fibers and softwood fibers, the hardwood fibers comprising at least about 60 percent and the softwood fibers comprising less than about 40 percent of the total weight of the web. 
     
     
         19 . The creped tissue web of  claim 14 , wherein the olefin polymer comprises an alpha-olefin interpolymer of ethylene and at least one comonomer selected from the group consisting of a C 4-20  linear, branched or cyclic diene, vinyl acetate, and a compound represented by the formula H 2 C═CHR, wherein R is a C 1-20  linear, branched or cyclic alkyl group or a C 6-20  aryl group, or the alpha-olefin polymer comprises a copolymer of propylene with at least one comonomer selected from the group consisting of ethylene, a C 4-20  linear, branched or cyclic diene, and a compound represented by the formula H 2 C═CHR, wherein R is a C 1-20  linear, branched or cyclic alkyl group or a C 6-20  aryl group.
