Abstract

Fibrous structures that exhibit a Tensile Ratio of less than 1.75 and/or less than 1.49 as measured according to the Tensile Strength Test Method described herein and a Geometric Mean Modulus (GM Modulus) of less than 1402.4 g/cm at 15 g/cm and/or a Machine Direction Modulus (MD Modulus) of less than 1253.4 g/cm at 15 g/cm and/or a Cross Machine Direction Modulus (CD Modulus) of less than 1569.2 g/cm at 15 g/cm, are provided.

Claims (20)

1. An embossed multi-ply fibrous structure that exhibits a Tensile Ratio of greater than 1.33 to less than 1.96 as measured according to the Tensile Strength Test Method and a GM Tangent Modulus of greater than 0 g/cm to less than 935 g/cm at 15 g/cm as measured according to the Modulus Test Method.

2. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure comprises cellulosic pulp fibers.

3. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure comprises a through-air-dried fibrous structure ply.

4. The multi-ply fibrous structure according to claim 3 wherein the through-air-dried fibrous structure ply is a creped through-air-dried fibrous structure ply.

5. The multi-ply fibrous structure according to claim 3 wherein the through-air-dried fibrous structure ply is an uncreped through-air-dried fibrous structure ply.

6. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure comprises an uncreped fibrous structure ply.

7. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure exhibits temporary wet strength, but is void of permanent wet strength.

8. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure exhibits a Tensile Ratio of greater than 1.33 to less than 1.80.

9. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure exhibits a Tensile Ratio of greater than 1.33 to less than 1.75.

10. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure exhibits a Tensile Ratio of greater than 1.33 to less than 1.6.

11. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure exhibits a Tensile Ratio of greater than 1.33 to less than 1.5.

12. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure exhibits a Tensile Ratio of greater than 1.4 to less than 1.80.

13. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure exhibits a Tensile Ratio of greater than 1.4 to less than 1.75.

14. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure exhibits a Tensile Ratio of greater than 1.4 to less than 1.6.

15. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure further exhibits a MD Tangent Modulus of greater than 0 g/m to less than 950.2 g/cm at 15 g/cm as measured according to the Modulus Test Method.

16. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure exhibits a MD Tangent Modulus of greater than 0 g/cm to less than 845 g/cm at 15 g/cm as measured according to the Modulus Test Method.

17. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure is an embossed multi-ply fibrous structure having at least one embossed fibrous structure ply.

18. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure exhibits a basis weight of greater than 15 gsm to about 120 gsm as measured according to the Basis Weight Test Method.

19. A toilet tissue comprising the multi-ply fibrous structure according to claim 1 .

20. The toilet tissue according to claim 19 wherein the toilet tissue is in roll form.
