Abstract

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

Claims (18)

1 . 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 Slip Stick Coefficient of Friction as measured according to the Slip Stick Coefficient of Friction Test Method such that the sanitary tissue product exhibits Compressibility and Slip Stick Coefficient of Friction values such that the sanitary tissue product falls above a line having the following equation: y=0.1203x+12.913 graphed on a plot of Stack Compressibility (y-axis) to Slip-Stick [COF*10000] (x-axis).

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 sanitary tissue product comprises an embossed fibrous structure ply.

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

10 . 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 Slip Stick Coefficient of Friction as measured according to the Slip Stick Coefficient of Friction Test Method such that the sanitary tissue product exhibits Compressibility and Slip Stick Coefficient of Friction values such that the sanitary tissue product falls above a line having the following equation: y=0.0424x+24.017 graphed on a plot of Stack Compressibility (y-axis) to Slip-Stick [COF*10000] (x-axis).

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

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

13 . The multi-ply sanitary tissue product according to claim 10 wherein the sanitary tissue product comprises an embossed fibrous structure ply.

14 . The multi-ply sanitary tissue product according to claim 10 wherein the sanitary tissue product comprises a 3D patterned fibrous structure ply.

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

16 . The multi-ply sanitary tissue product according to claim 14 wherein the 3D patterned fibrous structure ply comprises a fabric creped fibrous structure ply.

17 . The multi-ply sanitary tissue product according to claim 14 wherein the 3D patterned fibrous structure ply comprises a belt creped fibrous structure ply.

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