First claim
Opening claim text (preview).
What is claimed is: 1 . A two-ply sanitary tissue product, comprising: at least about 5% to about 100% by weight non-wood fibers; wherein the two-ply sanitary tissue product comprises at least one multi-layered fibrous structure ply comprising a plurality of layers, wherein all of the layers of the at least one multi-layered fibrous structure ply comprise at least about 5% by weight of each layer of the non-wood fibers; and wherein the two-ply sanitary tissue product exhibits a formation index of less than about 65. 2 . The two-ply sanitary tissue product of claim 1 , wherein the at least one multi-layered fibrous structure ply comprises a structured fibrous structure ply. 3 . The two-ply sanitary tissue product of claim 1 , wherein the at least one multi-layered fibrous structure ply comprises a creped fibrous structure ply. 4 . The two-ply sanitary tissue product of claim 1 , wherein the two-ply sanitary tissue product exhibits a formation index of greater than about 30. 5 . The two-ply sanitary tissue product of claim 1 , wherein the two-ply sanitary tissue product comprises at least about 35% by weight non-wood fibers selected from the group consisting of bamboo, abaca, and mixtures thereof. 6 . The two-ply sanitary tissue product of claim 1 , wherein the two-ply sanitary tissue product comprises at least about 75% by weight non-wood fibers selected from the group consisting of bamboo, abaca, and mixtures thereof. 7 . The two-ply sanitary tissue product of claim 1 , wherein the two-ply sanitary tissue product comprises at least about 100% by weight non-wood fibers selected from the group consisting of bamboo, abaca, and mixtures thereof. 8 . The two-ply sanitary tissue product of claim 1 , wherein the two-ply sanitary tissue product exhibits a tensile ratio greater than about 1.0. 9 . The two-ply sanitary tissue product of claim 1 , wherein the two-ply sanitary tissue product exhibits a tensile ratio of at least about 1.5. 10 . A multi-ply sanitary tissue product, comprising: at least about 5% to about 100% by weight non-wood fibers; wherein the multi-ply sanitary tissue product comprises at least one multi-layered fibrous structure ply comprising a plurality of layers, wherein all of the layers of the at least one multi-layered fibrous structure ply comprise at least about 5% by weight of each layer of the non-wood fibers and wherein the at least one multi-layered fibrous structure ply forms an exterior ply of the multi-ply sanitary tissue product; and wherein the multi-ply sanitary tissue product exhibits a formation index of less than about 65. 11 . The multi-ply sanitary tissue product of claim 10 , wherein the at least one multi-layered fibrous structure ply comprises a structured fibrous structure ply. 12 . The multi-ply sanitary tissue product of claim 10 , wherein the multi-ply sanitary tissue product further comprises one or more additional fibrous plies. 13 . The multi-ply sanitary tissue product of claim 10 , wherein the multi-ply sanitary tissue product exhibits a formation index of greater than about 30. 14 . The multi-ply sanitary tissue product of claim 10 , wherein the multi-ply sanitary tissue product comprises at least about 35% by weight non-wood fibers selected from the group consisting of bamboo, abaca, and mixtures thereof. 15 . The multi-ply sanitary tissue product of claim 10 , wherein the multi-ply sanitary tissue product comprises at least about 75% by weight non-wood fibers selected from the group consisting of bamboo, abaca, and mixtures thereof. 16 . The multi-ply sanitary tissue product of claim 10 , wherein the multi-ply sanitary tissue product comprises at least about 100% by weight non-wood fibers selected from the group consisting of bamboo, abaca, and mixtures thereof. 17 . The multi-ply sanitary tissue product of claim 10 , wherein the multi-ply sanitary tissue product exhibits a tensile ratio greater than about 1.0. 18 . The multi-ply sanitary tissue product of claim 10 , wherein the multi-ply sanitary tissue product exhibits a tensile ratio of at least about 1.5.
