Abstract

Sanitary tissue products employing fibrous structures that exhibit a novel combination of compressibility properties, plate stiffness properties, and slip stick coefficient of friction properties, and methods for making same.

First claim

What is claimed is:

1. A sanitary tissue product roll comprising a multi-ply sanitary tissue product comprising a plurality of pulp fibers, wherein the multi-ply sanitary tissue product exhibits a Compressibility of greater than 36 mils/(log(g/in 2 )) as measured according to the Stack Compressibility Test Method, a Plate Stiffness of less than 3.75 N*mm as measured according to the Plate Stiffness Test Method, and a Slip Stick Coefficient of Friction of less than 500 (COF*10000) as measured according to the Slip Stick Coefficient of Friction Test Method.

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

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

4. The sanitary tissue product roll according to claim 1 wherein the multi-ply sanitary tissue product comprises an embossed fibrous structure ply.

5. The sanitary tissue product roll according to claim 1 wherein the multi-ply sanitary tissue product comprises a 3D patterned fibrous structure ply.

6. The sanitary tissue product roll according to claim 5 wherein the 3D patterned fibrous structure ply comprises a through-air-dried fibrous structure ply.

7. The sanitary tissue product roll according to claim 5 wherein the 3D patterned fibrous structure ply comprises a fabric creped fibrous structure ply.

8. The sanitary tissue product roll according to claim 5 wherein the 3D patterned fibrous structure ply comprises a belt creped fibrous structure ply.

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

10. The sanitary tissue product roll according to claim 1 wherein the multi-ply sanitary tissue product exhibits a Compressibility of greater than 37 mils/(log(g/in 2 )) as measured according to the Stack Compressibility Test Method.

11. The sanitary tissue product roll according to claim 10 wherein the multi-ply sanitary tissue product exhibits a Compressibility of greater than 38 mils/(log(g/in 2 )) as measured according to the Stack Compressibility Test Method.

12. The sanitary tissue product roll according to claim 11 wherein the multi-ply sanitary tissue product exhibits a Compressibility of greater than 40 mils/(log(g/in 2 )) as measured according to the Stack Compressibility Test Method.

13. The sanitary tissue product roll according to claim 12 wherein the multi-ply sanitary tissue product exhibits a Compressibility of greater than 42 mils/(log(g/in 2 )) as measured according to the Stack Compressibility Test Method.

14. The sanitary tissue product roll according to claim 13 wherein the multi-ply sanitary tissue product exhibits a Compressibility of greater than 46 mils/(log(g/in 2 )) as measured according to the Stack Compressibility Test Method.

15. The sanitary tissue product roll according to claim 1 wherein the multi-ply sanitary tissue product exhibits a Plate Stiffness of less than 3.6 N*mm as measured according to the Plate Stiffness Test Method.

16. The sanitary tissue product roll according to claim 15 wherein the multi-ply sanitary tissue product exhibits a Plate Stiffness of less than 3.5 N*mm as measured according to the Plate Stiffness Test Method.

17. The sanitary tissue product roll according to claim 16 wherein the multi-ply sanitary tissue product exhibits a Plate Stiffness of less than 3.25 N*mm as measured according to the Plate Stiffness Test Method.

18. The sanitary tissue product roll according to claim 17 wherein the multi-ply sanitary tissue product exhibits a Plate Stiffness of less than 3 N*mm as measured according to the Plate Stiffness Test Method.

19. The sanitary tissue product roll according to claim 1 wherein the multi-ply sanitary tissue product exhibits a Slip Stick Coefficient of Friction of less than 450 (COF*10000) as measured according to the Slip Stick Coefficient of Friction Test Method.

20. The sanitary tissue product roll according to claim 19 wherein the multi-ply sanitary tissue product exhibits a Slip Stick Coefficient of Friction of less than 400 (COF*10000) as measured according to the Slip Stick Coefficient of Friction Test Method.
