Abstract

Fibrous structures that include design elements and more particularly to fibrous structures that have a design element having a primary design element and two, different secondary design elements that are associated with one another via the primary design element and methods for making such fibrous structures are provided.

Claims

1. A fibrous structure comprising a design element comprising a primary design element and two, different secondary design elements that are associated with each other via the primary design element at an angle of greater than 100°

but less than 180°

as measured according to the Secondary Design Element Angle Test Method.

2. The fibrous structure according to claim 1 wherein the primary design element exhibits reflection symmetry.

3. The fibrous structure according to claim 1 wherein the primary design element exhibits rotational symmetry.

4. The fibrous structure according to claim 1 wherein the primary design element comprises a line element embossment.

5. The fibrous structure according to claim 1 wherein the primary design element comprises a dot embossment.

6. The fibrous structure according to claim 1 wherein the design element comprises a representation of a flower.

7. The fibrous structure according to claim 1 wherein at least one of the two, different secondary design elements comprises a line element embossment.

8. The fibrous structure according to claim 1 wherein the two, different secondary design elements are associated with each other via the primary design element at an angle of greater than 120°

to about 150°

as measured according to the Secondary Design Element Angle Test Method.

9. The fibrous structure according to claim 1 wherein the fibrous structure is in roll form.

10. A single- or multi-ply sanitary tissue product comprising a fibrous structure according to claim 1.

11. A fibrous structure comprising a first design element comprising a primary design element and two, different secondary design elements that are associated with each other via the primary design element at an angle of greater than 100°

to about 150°

as measured according to the Secondary Design Element Angle Test Method and a second design element different from the first design element, wherein the second design element comprises a primary design element and two, different secondary design elements that are associated with each other via the primary design element at an angle of greater than 155°

to about 175°

as measured according to the Secondary Design Element Angle Test Method.

12. The fibrous structure according to claim 11 wherein the ratio of the number of first design elements to the number of second design elements is greater than 1.5:

1.

13. The fibrous structure according to claim 11 wherein the primary design element exhibits reflection symmetry.

14. The fibrous structure according to claim 11 wherein the primary design element exhibits rotational symmetry.

15. The fibrous structure according to claim 11 wherein the primary design element comprises a line element embossment.

16. The fibrous structure according to claim 11 wherein the primary design element comprises a dot embossment.

17. The fibrous structure according to claim 11 wherein at least one of the first and second design elements comprises a representation of a flower.

18. The fibrous structure according to claim 11 wherein at least one of the two, different secondary design elements comprises a line element embossment.

19. The fibrous structure according to claim 11 wherein the two, different secondary design elements are associated with each other via the primary design element at an angle of greater than 120°

to about 150°

as measured according to the Secondary Design Element Angle Test Method.

20. The fibrous structure according to claim 11 wherein the fibrous structure is in roll form.

21. A single- or multi-ply sanitary tissue product comprising a fibrous structure according to claim 11.

22. A fibrous structure comprising a primary design element and two, different secondary design elements associated with the primary design element, wherein the primary design element exhibits a embossment height of at least 50 μ

m or greater than the embossment height of the secondary design elements as measured according to the Embossment Height Test Method.

23. A fibrous structure comprising a primary design element and two, different secondary design elements associated with the primary design element, wherein the primary design element comprises a line element embossment having a first line element width and the secondary design elements comprising a line element embossment having a second line element width that is different from the first line element width.

24. A fibrous structure comprising a primary design element and two, different secondary design elements associated with the primary design element, wherein the primary design element has a maximum span between any two line element embossments within the primary design element and wherein the ratio of the average distance between centroids of the two secondary design elements from the centroid of the primary design element relative to the primary design element maximum span is at least 0.4 but less than 3.

25. A method for making a fibrous structure comprising a design element, the method comprising the step of imparting a design element comprising a primary design element and two, different secondary design elements that are associated with each other via the primary design element at an angle of greater than 120°

but less than 175°

as measured according to the Secondary Design Element Angle Test Method to a fibrous structure.

26. The method according to claim 25 wherein the step of imparting a design element comprises contacting a molding member comprising a design element with a fibrous structure such that the design element is imparted to the fibrous structure.

27. The method according to claim 25 wherein the step of imparting a design element comprises passing a fibrous structure through an embossing nip formed by at least one embossing roll comprising a design element such that the design element is imparted to the fibrous structure.
