Abstract

Embossed fibrous structures having one or more line element embossments and one or more linear elements and to methods for making same are provided.

First claim

What is claimed is:

1. A through-air-dried fibrous structure comprising a plurality of linear elements wherein at least one of the linear elements is substantially continuous and one or more line element embossments wherein at least one of the line element embossments overlaps one or more of the linear elements, the line element embossments having a width W 1 and the linear elements having a width W 2 , wherein the ratio of W 2 to W 1 is 1:4 or less and wherein W 1 is greater than 1.0 mm, and wherein at least one of the line element embossments is a partially enclosed line element embossment.

2. The fibrous structure according to claim 1 wherein the linear elements are present in at least one region and at least one of the line element embossments is present in a different region.

3. The fibrous structure according to claim 1 wherein two or more of the linear elements exhibit different widths.

4. The fibrous structure according to claim 1 wherein the linear elements are uniformly spaced apart from each other.

5. The fibrous structure according to claim 1 wherein the linear elements are non-uniformly spaced apart from each other.

6. The fibrous structure according to claim 1 wherein at least one of the line element embossments exhibits a uniform line element width.

7. The fibrous structure according to claim 1 wherein at least one of the line element embossments exhibits a non-uniform line element width.

8. The fibrous structure according to claim 1 wherein the plurality of the linear elements are oriented in substantially the machine direction on the fibrous structure.

9. The fibrous structure according to claim 1 wherein the plurality of the linear elements are oriented in substantially the cross-machine direction on the fibrous structure.

10. The fibrous structure according to claim 1 wherein at least one of the linear elements is imparted to the fibrous structure during the fibrous structure making process.

11. The fibrous structure according to claim 1 wherein at least one of the linear elements is imparted to the fibrous structure by an embossing process.

12. The fibrous structure according to claim 1 wherein at least one of the line element embossments is an enclosed line element embossment.

13. The fibrous structure according to claim 1 wherein the plurality of linear elements are spaced apart from one another at a distance of at least 0.30 mm.

14. The fibrous structure according to claim 1 wherein the plurality of linear elements are spaced apart from one another at a distance of less than 3.0 mm.

15. The fibrous structure according to claim 1 wherein at least one of the line element embossments exhibits a line element width of at least 0.30 mm.

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