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 sanitary tissue product comprising a plurality of pulp fibers, wherein the sanitary tissue product exhibits a Compressibility of greater than 34 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 sanitary tissue product comprises an embossed fibrous structure ply.

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

10. A sanitary tissue product roll comprising a creped sanitary tissue product comprising at least one through-air-dried fibrous structure ply, wherein the creped sanitary tissue product exhibits a Compressibility of greater than 34 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.

11. The sanitary tissue product roll according to claim 10 wherein the pulp fibers comprise wood pulp fibers.

12. The sanitary tissue product roll according to claim 10 wherein the pulp fibers comprise non-wood pulp fibers.

13. The sanitary tissue product roll according to claim 10 wherein the through-air-dried fibrous structure ply is an embossed through-air-dried fibrous structure ply.

14. The sanitary tissue product roll according to claim 13 wherein the through-air-dried fibrous structure ply comprises a 3D patterned through-air-dried fibrous structure ply.

15. The sanitary tissue product roll according to claim 10 wherein the creped sanitary tissue product comprises a fabric creped fibrous structure ply.

16. The sanitary tissue product roll according to claim 10 wherein the creped sanitary tissue product comprises a belt creped fibrous structure ply.

17. The sanitary tissue product roll according to claim 10 wherein the creped sanitary tissue product comprises a conventional wet-pressed fibrous structure ply.

18. A sanitary tissue product roll comprising a creped sanitary tissue product comprising a plurality of pulp fibers, wherein the creped sanitary tissue product exhibits a Compressibility of greater than 21 mils/(log(g/in 2 )) as measured according to the Stack Compressibility Test Method, a Plate Stiffness of less than 3.8 N*mm as measured according to the Plate Stiffness Test Method, and a Slip Stick Coefficient of Friction of less than 340 (COF*10000) as measured according to the Slip Stick Coefficient of Friction Test Method.

19. The sanitary tissue product roll according to claim 18 wherein the pulp fibers comprise wood pulp fibers.

20. The sanitary tissue product roll according to claim 18 wherein the pulp fibers comprise non-wood pulp fibers.
