Abstract

Fibrous structures having a surface including a plurality of line elements and a method for making same is provided.

First claim

What is claimed is:

1. A toilet tissue comprising a molded fibrous structure comprising pulp fibers and a temporary wet strength agent, and having a molded surface comprising at least two first line elements extending in a first direction and at least two second line elements extending in a second direction different from the first direction, wherein at least one of the first line elements is connected to and is coplanar with at least one of the second line elements at an angle of from about 10° to about 85°, wherein the ratio of the average distance between the two second line elements and the average distance between the two first line elements is greater than 1 and wherein at least one of the first line elements and second line elements is a molded line element, wherein the toilet tissue exhibits a basis weight of greater than 15 g/m 2 to about 120 g/m 2 .

2. The toilet tissue according to claim 1 wherein the surface comprises a plurality of first line elements.

3. The toilet tissue according to claim 2 wherein the first line elements are substantially parallel to one another.

4. The toilet tissue according to claim 1 wherein the surface comprises a plurality of second line elements.

5. The toilet tissue according to claim 4 wherein the second line elements are substantially parallel to one another.

6. The toilet tissue according to claim 1 wherein the surface comprises a plurality of first line elements and a plurality of second line elements.

7. The toilet tissue according to claim 6 wherein the ratio of the maximum average distance between adjacent second line elements and the maximum average distance between adjacent first line elements is greater than 1.

8. The toilet tissue according to claim 1 wherein at least one of the first line elements comprises a curvilinear line element.

9. The toilet tissue according to claim 1 wherein at least one of the second line elements comprises a curvilinear line element.

10. The toilet tissue according to claim 1 wherein the second line element is connected to the first line element at an angle of from about 10° to about 70°.

11. The toilet tissue according to claim 1 wherein the surface further comprises a third line element that intersects at least one second line element.

12. The toilet tissue according to claim 11 wherein the third line element intersects the second line element at an angle of from about 10° to about 90°.

13. The toilet tissue according to claim 12 wherein the third line element intersects that second line element at an angle of from about 40° to about 90°.

14. The toilet tissue according to claim 11 wherein the third line element connects to at least one of the first line elements.

15. The toilet tissue according to claim 14 wherein the third line element connects to the first line element at an angle of from about 5° to about 90°.

16. The toilet tissue according to claim 15 wherein the third line element connects to the first line element at an angle of from about 10° to about 85°.

17. The toilet tissue according to claim 11 wherein at least one of the second line elements intersects the third line element.

18. The toilet tissue according to claim 17 wherein the second line element intersects the third line element at an angle of from about 10° to about 90°.

19. The toilet tissue according to claim 18 wherein the second line element intersects the third line element at an angle of from about 10° to about 45°.

20. The toilet tissue according to claim 1 wherein the pulp fibers comprise softwood pulp fibers.
