Abstract

Sanitary tissue products employing fibrous structures that exhibit novel tear alone or in combination with tensile properties and methods for making same.

Claims (19)

1. A creped sanitary tissue product comprising a plurality of pulp fibers, wherein the creped sanitary tissue product comprises a surface softening agent, but is void of other surface chemistries and is void of permanent wet strength, wherein the creped sanitary tissue product exhibits a GM Tear Value as measured according to the Tear Strength Test Method and a GM Tensile Value as measured according to the Dry Tensile Test Method such that the creped sanitary tissue product falls above a line having the following equation: y=0.0122x+18.05 graphed on a plot of GM Tear Value (y-axis) to GM Tensile Value (x-axis).

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 comprises an embossed fibrous structure ply.

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

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

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

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

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

10. A dispersible, creped sanitary tissue product comprising a plurality of pulp fibers, wherein the dispersible, creped sanitary tissue product comprises a surface softening agent, but is void of other surface chemistries and wherein the dispersible, creped sanitary tissue product exhibits a GM Tear Value as measured according to the Tear Strength Test Method and a GM Tensile Value as measured according to the Dry Tensile Test Method such that the dispersible, creped sanitary tissue product falls above a line having the following equation: y=0.0122x+18.05 graphed on a plot of GM Tear Value (y-axis) to GM Tensile Value (x-axis).

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

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

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

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

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

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

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

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

19. A creped, multi-ply sanitary tissue product comprising a plurality of pulp fibers, wherein the creped, multi-ply sanitary tissue product comprises a surface softening agent, but is void of other surface chemistries and wherein the creped, multi-ply sanitary tissue product exhibits a GM Tensile Value of less than 700 Win as measured according to the Dry Tensile Test Method and wherein the creped, multi-ply sanitary tissue product exhibits a GM Tear Value as measured according to the Tear Test Method and a GM Tensile Value as measured according to the Dry Tensile Test Method such that the creped, multi-ply sanitary tissue product falls above a line having the following equation: y=0.0122x+18.05 graphed on a plot of GM Tear Value (y-axis) to GM Tensile Value (x-axis).
