Abstract

Sanitary tissue products employing fibrous structures that exhibit novel compressibility properties alone and in combination with plate stiffness properties and methods for making same.

First claim

What is claimed is:

1. A sanitary tissue product comprising at least one 3D patterned, embossed fibrous structure ply comprising a plurality of pulp fibers, wherein the sanitary tissue product exhibits a Compressibility of greater than 46.0 mils/(log(g/in 2 )) as measured according to the Stack Compressibility and Resilient Bulk Test Method and a Plate Stiffness of less than 5.20 N*mm as measured according to the Plate Stiffness Test Method.

2. The sanitary tissue product according to claim 1 wherein the pulp fibers comprise wood pulp fibers.

3. The sanitary tissue product according to claim 1 wherein the pulp fibers comprise non-wood pulp fibers.

4. The sanitary tissue product according to claim 1 wherein the sanitary tissue product further comprises a conventional wet-pressed fibrous structure ply.

5. A multi-ply sanitary tissue product comprising at least one creped through-air-dried fibrous structure ply comprising a plurality of pulp fibers, wherein the sanitary tissue product exhibits a Compressibility of greater than 36.0 mils/(log(g/in 2 )) as measured according to the Stack Compressibility and Resilient Bulk Test Method and a Plate Stiffness of less than 8.30 N*mm as measured according to the Plate Stiffness Test Method.

6. The multi-ply sanitary tissue product according to claim 5 wherein the pulp fibers comprise wood pulp fibers.

7. The multi-ply sanitary tissue product according to claim 5 wherein the pulp fibers comprise non-wood pulp fibers.

8. The multi-ply sanitary tissue product according to claim 5 wherein the creped through-air-dried fibrous structure ply is an embossed creped through-air-dried fibrous structure ply.

9. The multi-ply sanitary tissue product according to claim 5 wherein the creped through-air-dried fibrous structure ply is a 3D patterned creped through-air-dried fibrous structure ply.

10. The multi-ply sanitary tissue product according to claim 5 wherein the creped through-air-dried fibrous structure ply is a non-lotioned creped through-air-dried fibrous structure ply.

11. A multi-ply sanitary tissue product comprising a plurality of pulp fibers, wherein the sanitary tissue product exhibits a Compressibility as measured according to the Stack Compressibility and Resilient Bulk Test Method and a Plate Stiffness as measured according to the Plate Stiffness Test Method such that the sanitary tissue product exhibits Compressibility and Plate Stiffness values such that the sanitary tissue product falls above a line having the following equation: y=1.5152x+43.061 graphed on a plot of Compressibility (y-axis) to Plate Stiffness (x-axis).

12. The multi-ply sanitary tissue product according to claim 11 wherein the pulp fibers comprise wood pulp fibers.

13. The multi-ply sanitary tissue product according to claim 11 wherein the pulp fibers comprise non-wood pulp fibers.

14. The multi-ply sanitary tissue product according to claim 11 wherein the sanitary tissue product comprises an embossed fibrous structure ply.

15. The multi-ply sanitary tissue product according to claim 11 wherein the sanitary tissue product comprises a 3D patterned fibrous structure ply.
