Abstract

The present disclosure provides high bulk tissue products, as well as an apparatus and methods for manufacturing the same. The tissue products provided herein not only have high bulk, but they also have improved surface smoothness, particularly compared to tissue products of similar basis weights.

First claim

We claim:

1. A rolled tissue product comprising a tissue web spirally wound into a roll, the web having a wave-like patterned three-dimensional surface topography comprising valleys and ridges, a basis weight greater than about 34 grams per square meter (gsm), a geometric mean tensile (GMT) greater than about 2000 g/3″ and a Surface Smoothness S90 less than about 75.0 μm, wherein the wound roll has a Roll Bulk greater than about 15 cc/g.

2. The tissue product of claim 1 wherein the tissue web has a sheet bulk from about 15 to about 25 cc/g.

3. The tissue product of claim 1 wherein the wound roll has a Roll Firmness less than about 8.0 mm.

4. The tissue product of claim 1 wherein the wound roll has a Roll Bulk greater than about 18 cc/g and a Roll Firmness from about 5.0 to about 8.0 mm.

5. The tissue product of claim 1 wherein the tissue web has a geometric mean slope less than about 12,000 g/3″.

6. The tissue product of claim 1 wherein the tissue web has a geometric mean stretch greater than about 10 percent.

7. The tissue product of claim 1 wherein the tissue web comprises one ply.

8. The tissue product of claim 1 wherein the tissue web has a GMT from about 2200 to about 2700 g/3″ and Stiffness Index from about 4.0 to about 6.0.

9. The tissue product of claim 1 wherein the tissue web comprises a through-air dried web.

10. The tissue product of claim 1 wherein the ridges have a width from about 0.7 to about 1.5 mm, an amplitude from about 18 to 22 mm and a wavelength from about 80 to about 120 mm.

11. The tissue product of claim 10 wherein the ridges are separated from one another by valleys having a width greater than about 0.7 mm.

12. A single-ply tissue product having a wave-like patterned three-dimensional surface topography comprising valleys and ridges, a basis weight from about 30 to about 40 grams per square meter (gsm) a sheet bulk greater than about 20 cc/g and a Surface Smoothness S90 from about 60.0 to about 75.0 μm and a geometric mean tensile (GMT) greater than about 2000 g/3″.

13. The single-ply tissue product of claim 12 having a geometric mean slope less than about 12,000 g/3″.

14. The single-ply tissue product of claim 12 having a geometric mean stretch greater than about 10 percent.

15. The single-ply tissue product of claim 12 wherein the single-ply tissue web has a Surface Smoothness S90 value is from about 70.0 to about 75.0 μm.

16. The single-ply tissue product of claim 12 wherein the single-ply tissue web has a Surface Smoothness Sa value from about 15.0 to about 18.0 μm.

17. The single-ply tissue product of claim 12 wherein the single-ply tissue web has a Surface Smoothness Sq value from about 20.0 to about 30.0 μm.

18. The single-ply tissue product of claim 12 wherein the single-ply tissue web comprises an uncreped through-air dried web.
