Claims19
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.
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.
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.
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.
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.
