Abstract

A fibrous structure having a total dry tensile strength of greater than about 59 g/cm 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 total dry tensile strength of greater than about 59 g/cm 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 having a total dry tensile strength of greater than about 59 g/cm, an initial total wet tensile strength of less than about 78 g/cm (200 g/in), a basis weight ranging from between 15 g/m 2 (9.2 lbs/3000 ft 2 ) to about 120 g/m 2 (73.8 lbs/3000 ft 2 ), and 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.

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 of 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 having a total dry tensile strength of greater than about 59 g/cm, an initial total wet tensile strength of greater than about 118 g/cm (300 g/in), a basis weight ranging from 15 g/m 2 (9.2 lbs/3000 ft 2 ) to about 120 g/m 2 (73.8 lbs/3000 ft 2 ), and 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.

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 creped.

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 of 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.
