Abstract

Sanitary tissue products having non-wood fibers selected from the group consisting of bamboo, abaca, and mixtures thereof and exhibiting a TS7 of less than about 14 dB V2 rms and/or a TS750 less than about 45 dB V2 rms.

First claim

What is claimed is:

1 . A two-ply sanitary tissue product, comprising:
at least about 5% to about 100% by weight non-wood fibers selected from the group consisting of bamboo, abaca, and mixtures thereof; 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 the layer of the non-wood fibers; and wherein the two-ply sanitary tissue product exhibits a TS7 of less than about 14 dB V2 rms.

2 . The two-ply sanitary tissue product of claim 1 , wherein the non-wood fibers consist of bamboo fibers.

3 . The two-ply sanitary tissue product of claim 1 , wherein the two-ply sanitary tissue product is a two-ply toilet tissue.

4 . The two-ply sanitary tissue product of claim 1 , wherein the two-ply sanitary tissue product comprises greater than about 30% to about 100% by weight of the non-wood fibers.

5 . A two-ply sanitary tissue product, comprising:
at least about 5% to about 100% by weight bamboo 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 the layer of the bamboo fibers; and
wherein the two-ply sanitary tissue product exhibits a TS750 less than about 45 dB V2 rms.

6 . The two-ply sanitary tissue product of claim 5 , wherein the two-ply sanitary tissue product is a two-ply multi-ply toilet tissue.

7 . The two-ply sanitary tissue product of claim 5 , wherein the two-ply sanitary tissue product comprises greater than about 30% to about 100% by weight of the bamboo fibers.

8 . The two-ply sanitary tissue product of claim 5 , wherein the two-ply sanitary tissue product comprises greater than about 75% to about 100% by weight of the bamboo fibers.

9 . A two-ply sanitary tissue product, comprising:
at least about 5% to about 100% by weight non-wood fibers selected from the group consisting of bamboo, abaca, and mixtures thereof; wherein the two-ply sanitary tissue product comprises 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 the layer of non-wood fibers; and
wherein the two-ply sanitary tissue product exhibits a TS750 less than about 45 dB V2 rms.

10 . The two-ply multi-ply sanitary tissue product of claim 9 , wherein the two-ply sanitary tissue product comprises a structured fibrous structure.

11 . The two-ply sanitary tissue product of claim 9 , wherein the two-ply sanitary tissue product is a two-ply multi-ply toilet tissue.

12 . The two-ply sanitary tissue product of claim 9 , wherein the two-ply sanitary tissue product comprises greater than about 30% to about 100% by weight of the non-wood fibers.

13 . The two-ply sanitary tissue product of claim 9 , wherein the two-ply sanitary tissue product exhibits a TS750 of less than 40 dB V2 rms.

14 . The two-ply sanitary tissue product of claim 9 , wherein the two-ply sanitary tissue product exhibits a TS750 of from about 25 to about 35 dB V2 rms.

15 . A multi-ply sanitary tissue product, comprising:
at least about 5% to about 100% by weight non-wood fibers selected from the group consisting of bamboo, abaca, and mixtures thereof; 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 the 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 TS7 of less than about 14 dB V2 rms.

16 . The multi-ply sanitary tissue product of claim 15 , wherein the non-wood fibers consist of bamboo fibers.

17 . The multi-ply sanitary tissue product of claim 15 , wherein the multi-ply sanitary tissue product is a multi-ply toilet tissue.

18 . The multi-ply sanitary tissue product of claim 15 , wherein the multi-ply sanitary tissue product comprises greater than about 30% to about 100% by weight of the non-wood fibers.

19 . A multi-ply sanitary tissue product, comprising:
at least about 5% to about 100% by weight bamboo 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 the layer of the bamboo 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 TS750 less than about 45 dB V2 rms.

20 . The multi-ply sanitary tissue product of claim 19 , wherein the multi-ply sanitary tissue product is a multi-ply toilet tissue.
