Soft and strong fibrous structures and methods for making same

Abstract

Soft and strong fibrous structures and more particularly soft and strong fibrous structures that contains less softwood fibers than known fibrous structures and methods for making such soft and strong fibrous structures are provided.

1 . A sanitary tissue product comprising a layered fibrous structure comprising greater than 50% by weight on a dry fiber basis of pulp fibers, wherein less than 20% by weight on a dry fiber basis of the pulp fibers are softwood fibers, and wherein the fibrous structure exhibits a total dry tensile of greater than 300 g/in as measured according to the Total Dry Tensile Test Method. 
     
     
         2 . The sanitary tissue product of  claim 1 , wherein the fibrous structure is void of hardwood fibers. 
     
     
         3 . The sanitary tissue product of  claim 1 , wherein the pulp fibers comprise trichome fibers. 
     
     
         4 . The sanitary tissue product of  claim 3 , wherein one or more of the trichome fibers are derived from a plant in the Stachys genus. 
     
     
         5 . The sanitary tissue product of  claim 4 , wherein one or more of the trichome fibers are derived from a plant Stachys byzantina. 
     
     
         6 . A fibrous structure comprising a plurality of pulp fibers, wherein greater than 0% but less than 20% by weight on a dry fiber basis of the pulp fibers are softwood fibers, and wherein the fibrous structure comprises fibers derived from a fiber-producing source that has a growing cycle of less than 800 days. 
     
     
         7 . The fibrous structure of  claim 6 , wherein the fiber-producing source has a growing cycle of less than 400 days. 
     
     
         8 . The fibrous structure of  claim 6 , wherein the fiber-producing source has a growing cycle of less than 200 days. 
     
     
         9 . The fibrous structure of  claim 6 , wherein the fiber-producing source has a growing cycle of less than 100 days. 
     
     
         10 . The fibrous structure of  claim 6 , wherein the fibrous structure is a through-air-dried fibrous structure. 
     
     
         11 . The fibrous structure of  claim 6 , wherein the fibrous structure is void of hardwood fibers. 
     
     
         12 . A fibrous structure comprising a plurality of fibers and being void of surface softening agents, wherein the fibrous structure exhibits a Slip-and-Stick Coefficient of Friction of less than 0.8 as measured according to the Slip-and-Stick Coefficient of Friction Test Method. 
     
     
         13 . The fibrous structure of  claim 12 , wherein the fibrous structure comprises greater than 0% but less than 20% by weight on a dry fiber basis of softwood fibers. 
     
     
         14 . The fibrous structure of  claim 12 , wherein the fibrous structure comprises trichome fibers. 
     
     
         15 . The fibrous structure of  claim 12 , wherein the fibrous structure exhibits a Slip-and-Stick Coefficient of Friction of less than 0.75. 
     
     
         16 . A fibrous structure comprising individualized trichomes and greater than 0% but less than 20% by weight on a dry fiber basis of softwood fibers, wherein the fibrous structure exhibits a Slip-and-Stick Coefficient of Friction as measured according to the Slip-and-Stick Coefficient of Friction Test Method of less than 20% of the Slip-and-Stick Coefficient of Friction of the same fibrous structure void of the individualized trichomes. 
     
     
         17 . A fibrous structure comprising fibers, wherein the weight ratio of softwood fibers to non-softwood fibers within the fibrous structure is less than 1:4. 
     
     
         18 . The fibrous structure of  claim 17 , wherein the fibers comprise trichome fibers. 
     
     
         19 . The fibrous structure of  claim 17 , wherein the fibrous structure is a through-air-dried fibrous structure.
