Abstract

A web substrate having at least one embossed ply having a surface thereof is disclosed. The surface has surface area comprising at least about 0.2 percent line embossments and a ratio of line embossment area to dot embossment area greater than 1.5.

First claim

What is claimed:

1. A web substrate having at least one embossed ply having a surface thereof, wherein said surface has surface area comprising line embossments having a line embossment area, and dot embossments having a dot embossment area, the line embossments and dot embossments form a regular repeating embossing pattern, wherein said surface area has at least about 0.2 percent line embossments and wherein the ratio of line embossment area to dot embossment area is greater than 1.5, and wherein the web substrate forms a fibrous structure exhibiting a total dry tensile strength of greater than about 59 g/cm.

2. The web substrate of claim 1 wherein said ratio of line embossment area to dot embossment area is greater than 2.0.

3. The web substrate of claim 2 wherein said ratio of line embossment area to dot embossment area is greater than 3.0.

4. The web substrate of claim 1 wherein said surface area further comprises at least about 0.2 percent dot embossments.

5. The web substrate of claim 1 wherein said surface area further comprises from about 5.0 percent to about 20.0 percent line embossments.

6. The web substrate of claim 5 wherein said surface area further comprises from about 6.5 percent to about 12.0 percent line embossments.

7. The web substrate of claim 1 wherein said web substrate is a fibrous structure.

8. The web substrate of claim 7 wherein said fibrous structure is a paper web.

9. The web substrate of claim 1 wherein said web substrate is a through air dried.

10. The web substrate of claim 1 wherein said web substrate is creped.
