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 multi-ply sanitary tissue product comprising a plurality of pulp fibers, wherein the multi-ply 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 multi-ply sanitary tissue product according to claim 1 wherein the pulp fibers comprise wood pulp fibers.

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

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

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

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

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

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

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

10. A creped multi-ply sanitary tissue product comprising at least one through-air-dried fibrous structure ply, 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.

11. The creped multi-ply sanitary tissue product according to claim 10 wherein the pulp fibers comprise wood pulp fibers.

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

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

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

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

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

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

18. A creped multi-ply sanitary tissue product comprising a plurality of pulp fibers, wherein the creped multi-ply 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 creped multi-ply sanitary tissue product according to claim 18 wherein the pulp fibers comprise wood pulp fibers.

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