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 (18)

1. A sanitary tissue product having a fibrous structure comprising fibers, wherein the sanitary tissue product exhibits a Tensile Ratio of greater than 1.33 to less than 1.75 as measured according to the Tensile Strength Test Method and a MD Tangent Modulus of less than 845 g/cm as measured according to the Modulus Test Method.

2. The sanitary tissue product according to claim 1 wherein the fibrous structure comprises cellulosic pulp fibers.

3. The sanitary tissue product according to claim 1 wherein the sanitary tissue product is through-air-dried.

4. The sanitary tissue product according to claim 1 wherein the sanitary tissue product is uncreped.

5. The sanitary tissue product according to claim 1 wherein the sanitary tissue product is embossed.

6. The sanitary tissue product according to claim 1 wherein the sanitary tissue product exhibits a basis weight of greater than 15 gsm to about 120 gsm as measured according to the Basis Weight Test Method.

7. A sanitary tissue product comprising fibers such that the sanitary tissue product exhibits a Tensile Ratio of greater than 1.33 to less than 1.75 as measured according to the Tensile Strength Test Method and a CD Tangent Modulus of less than 980 g/cm as measured according to the Modulus Test Method.

8. The sanitary tissue product according to claim 7 wherein the fibrous structure comprises cellulosic pulp fibers.

9. The sanitary tissue product according to claim 7 wherein the sanitary tissue product is through-air-dried.

10. The sanitary tissue product according to claim 7 wherein the sanitary tissue product is uncreped.

11. The sanitary tissue product according to claim 7 wherein the sanitary tissue product is embossed.

12. The sanitary tissue product according to claim 7 wherein the sanitary tissue product exhibits a basis weight of greater than 15 gsm to about 120 gsm as measured according to the Basis Weight Test Method.

13. A sanitary tissue product comprising fibers such that the sanitary tissue product exhibits a Tensile Ratio of greater than 1.33 to less than 1.75 as measured according to the Tensile Strength Test Method and a GM Tangent Modulus of less than 935 g/cm as measured according to the Modulus Test Method.

14. The sanitary tissue product according to claim 13 wherein the fibrous structure comprises cellulosic pulp fibers.

15. The sanitary tissue product according to claim 13 wherein the sanitary tissue product is through-air-dried.

16. The sanitary tissue product according to claim 13 wherein the sanitary tissue product is uncreped.

17. The sanitary tissue product according to claim 13 wherein the sanitary tissue product is embossed.

18. The sanitary tissue product according to claim 13 wherein the sanitary tissue product exhibits a basis weight of greater than 15 gsm to about 120 gsm as measured according to the Basis Weight Test Method.
