Abstract

A fibrous structure having a density (measured at 95 g/in 2 ) of less than about 0.60 g/cm 3 and at least one embossed ply having a surface thereof is disclosed. The surface has a surface area comprising from about 10.0 percent to about 20.0 percent line embossments. Also, a fibrous structure having at least two plies is disclosed. One of the two plies has a density (measured at 95 g/in 2 ) of less than about 0.60 g/cm 3 and at least one embossed ply having a surface thereof. The surface has a surface area comprising from about 10.0 percent to about 20.0 percent line embossments.

First claim

What is claimed is:

1. A fibrous structure comprising a pattern densified through air dried web having continuous high bulk zones and discrete high density zones disposed within said continuous high bulk zones and having a density (measured at 95 g/in 2 ) of less than about 0.60 g/cm 3 and an initial total wet tensile strength of less than about 78 g/cm (200 g/in), at least one embossed ply having a surface thereof, wherein said surface has a surface area comprising from about 10.0 percent to about 20.0 percent line embossments, said line embossments comprising an asymmetrical embossing pattern.

2. The fibrous structure of claim 1 wherein said surface area comprises from 0.0 percent to about 1.2 percent dot embossments.

3. The fibrous structure of claim 1 wherein said fibrous structure is creped.

4. The fibrous structure of claim 1 wherein said fibrous structure is uncreped.

5. The fibrous structure of claim 1 wherein said fibrous structure is a paper web.

6. The fibrous structure of claim 1 wherein said surface has an irregular and asymmetrical embossing pattern disposed thereon.

7. The fibrous structure of claim 1 wherein said surface area has a ratio of line embossment area to dot embossment area greater than 1.

8. The fibrous structure of claim 1 wherein said fibrous structure is through-air-dried.

9. The fibrous structure of claim 1 wherein said fibrous structure comprises at least 2 plies.

10. The fibrous structure of claim 1 wherein said fibrous structure is a product selected from the group consisting of absorbent towels, facial tissue, and toilet tissue.

11. A fibrous structure having at least two plies, one of said two plies comprising a pattern densified through air dried web having continuous high bulk zones and discrete high density zones disposed within said continuous high bulk zones and having a density (measured at 95 g/in 2 ) of less than about 0.60 g/cm 3 and an initial total wet tensile strength of less than about 78 g/cm (200 g/in), at least one embossed ply having a surface thereof, wherein said surface has a surface area comprising from about 10.0 percent to about 20.0 percent line embossments, and wherein said surface has a total embossment footprint area to total surface area ranging from about 5 percent to about 40 percent.

12. The fibrous structure of claim 11 wherein said surface area comprises from 0.0 percent to about 1.2 percent dot embossments.

13. The fibrous structure of claim 11 wherein said fibrous structure is uncreped.

14. The fibrous structure of claim 11 wherein said fibrous structure is uncreped.

15. The fibrous structure of claim 11 wherein said fibrous structure is a paper web.

16. The fibrous structure of claim 11 wherein said surface has an irregular and asymmetrical embossing pattern disposed thereon.

17. The fibrous structure of claim 11 wherein said surface area has a ratio of line embossment area to dot embossment area greater than 1.

18. The fibrous structure of claim 11 wherein said fibrous structure is through-air-dried.

19. The fibrous structure of claim 11 wherein said fibrous structure comprises at least 2 plies.

20. The fibrous structure of claim 11 wherein said fibrous structure is a product selected from the group consisting of absorbent towels, facial tissue, and toilet tissue.
