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 basis weight greater than about 35 grams per square meter (gsm), a Stiffness Index from about 4 to about 8 and a geometric mean tensile (GMT) from about 700 to about 1200 g/3″, wherein the rolled tissue product has a Roll Structure greater than about 1.0.

2. The tissue product of claim 1 wherein the tissue web has a sheet bulk from about 12 to about 20 cc/g.

3. The tissue product of claim 1 wherein the wound roll has a roll bulk greater than about 10 cc/g and a Roll Firmness less than about 10 mm.

4. The tissue product of claim 1 wherein the wound roll has a roll bulk from about 14 to about 18 cc/g and a Roll Firmness from about 8 to about 10 mm.

5. The tissue product of claim 1 wherein the tissue web has a geometric mean slope less than about 10,000 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 comprises two or more plies.

9. The tissue product of claim 1 wherein the tissue web has a basis weight from about 38 to about 50 gsm.

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

11. The tissue product of claim 1 wherein the tissue web comprises an uncreped through-air dried web.

12. A rolled tissue product comprising a single-ply through-air dried tissue web spirally wound into a roll, the web having a basis weight greater than about 35 grams per square meter (gsm) a sheet bulk greater than about 12 cc/g, a Stiffness Index from about 6 to about 8 and a GMT from about 700 to about 1400 g/3″.

13. The rolled tissue product of claim 12 having a geometric mean slope less than about 10,000 g/3″.

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

15. The rolled tissue product of claim 12 wherein the single-ply tissue web comprises a through-air dried web.

16. A rolled tissue product comprising a single-ply tissue web spirally wound into a rolled tissue product, the rolled tissue product having a roll bulk from about 14 to about 18 cc/g and a Roll Firmness from about 8 to about 10 mm, and the single-ply tissue web having a sheet bulk greater than about 12 cc/g, a GMT from about 700 to about 1400 g/3″, and a Surface Smoothness S90 value less than about 105 μm.

17. The rolled tissue product of claim 16 wherein the single-ply tissue web has a basis weight from about 38 to about 50 gsm.

18. The rolled tissue product of claim 16 wherein the single-ply tissue web the Surface Smoothness S90 value is from about 70 to about 100 μm.

19. The rolled tissue product of claim 16 wherein the single-ply tissue web has a Surface Smoothness Sa value from about 15 to about 25 μm.

20. The rolled tissue product of claim 16 wherein the single-ply tissue web has a Surface Smoothness Sq value from about 20 to about 40 μm.
