Abstract

Embossed, multi-ply tissue products having consumer preferred physical properties and an aesthetically pleasing appearance such as a first tissue ply having a molded topographical pattern and a first embossed pattern comprising a plurality of embossed elements disposed thereon and a second tissue ply having a molded topographical pattern and a second embossed pattern comprising a plurality of dot emboss elements disposed thereon. The multi-ply tissue products generally have improved sheet bulk, such as a sheet bulk greater than about 15 cubic centimeters per gram (cc/g), and improved softness, such as an Average TS7 less than about 12.0 and more preferably less than about 11.0, such as from about 10.0 to about 12.0. The foregoing Average TS7 values may be obtained at a product geometric mean tensile strength (GMT) from about 800 to about 1,200 g/3″.

First claim

What is claimed is:

1. An embossed multi-ply tissue product comprising:
a. a first tissue ply having a molded topographical pattern and a first embossed pattern consisting essentially of a plurality of line embossed elements disposed thereon;
b. a second tissue ply having a molded topographical pattern and a second embossed pattern consisting essentially of a plurality of dot emboss elements disposed thereon,

wherein the density of dot emboss elements in the second embossed pattern ranges from about 7.5 to about 20 dot embossments per square centimeter and the pattern is substantially free from line emboss elements and covers from about 5 to about 10 percent of the second ply surface area and the embossed, multi-ply tissue product has a basis weight from about 20 to about 60 grams per square meter (gsm) and a bulk greater than about 15 cubic centimeters per gram (cc/g).

2. The embossed multi-ply tissue product of claim 1 wherein both the molded topographical pattern and the first embossed pattern comprise a plurality of line elements.

3. The embossed multi-ply tissue product of claim 1 wherein both the first and second embossed pattern comprise a plurality of wave-like linear elements.

4. The embossed multi-ply tissue product of claim 1 wherein the molded topographical pattern, the first embossed pattern and the second embossed pattern are different.

5. The embossed multi-ply tissue product of claim 1 wherein the dot emboss elements have a shape selected from the group consisting of circles, squares, rectangles, diamonds, and combinations thereof, and the dot emboss elements are arranged to form wave-like linear elements.

6. The embossed multi-ply tissue product of claim 1 wherein the molded topographical pattern comprises a plurality of parallel, substantially machine direction (MD) oriented linear elements having an element angle from about 1 to about 20 degrees.

7. The embossed multi-ply tissue product of claim 1 wherein the molded topographical pattern comprises a plurality of parallel and substantially MD oriented sinusoidal waves.

8. The embossed multi-ply tissue product of claim 1 wherein the molded topographical pattern comprises a plurality of parallel substantially MD oriented, continuous, wave-like ridges spaced apart from one another by valleys.

9. The embossed multi-ply tissue product of claim 8 wherein at least a first portion of the dot emboss elements overlay at least a portion of the wave-like ridges and at least a second portion of the dot emboss elements overlay at least a portion of the wave-like valleys.

10. The embossed multi-ply tissue product of claim 1 wherein the first embossing pattern is continuous and the plurality of line emboss elements are curvilinear and either open or closed.

11. The embossed multi-ply tissue product of claim 1 wherein first embossing pattern is substantially free from dot emboss elements and covers from about 10 to about 30 percent of the first ply surface area.

12. The embossed multi-ply tissue product of claim 1 wherein the first and the second tissue plies are through-air dried tissue webs and the molded topographical pattern is imparted by molding of the web to a through-air drying fabric.

13. The embossed multi-ply tissue product of claim 1 wherein the first and second tissue plies are adhesively bonded to one another at a plurality of bonded regions.

14. The embossed multi-ply tissue product of claim 13 wherein at least a portion of the bonded regions are formed between the line emboss elements of the first ply and the dot emboss elements of the second ply.

15. The embossed multi-ply tissue product of claim 14 wherein the embossed multi-ply tissue product has a geometric mean tensile strength (GMT) from about 800 to about 1,200 g/3″.

16. The embossed multi-ply tissue product of claim 15 wherein the embossed multi-ply tissue product has an Average TS7 value from about 10.0 to about 12.0.
