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 34 grams per square meter (gsm), a 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 any one of the foregoing claims wherein the wound roll has a Roll Firmness less than about 8.0 mm.

4 . The tissue product of claim 1 or 2 wherein the wound roll has a Roll Bulk greater than about 18 cc/g and the Roll Firmness is from about 5.0 to about 8.0 mm.

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

6 . The tissue product of any one of the foregoing claims wherein the tissue web has a geometric mean stretch greater than about 10 percent.

7 . The tissue product of any one of the foregoing claims wherein the tissue web comprises one ply.

8 . The tissue product of any one of the foregoing claims 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 any one of the foregoing claims wherein the tissue web comprises a through-air dried web.

10 . The tissue product of any one of the foregoing claims wherein the tissue web comprises an uncreped through-air dried web.

11 . A single-ply tissue product having 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 GMT greater than about 2000 g/3″.

12 . The single-ply tissue product of claim 11 having a geometric mean slope less than about 12,000 g/3″.

13 . The single-ply tissue product of any one of claim 11 or 12 having a geometric mean stretch greater than about 10 percent.

14 . The single-ply tissue product of any one of claims 11 through 13 wherein the single-ply tissue web has a basis weight from about 34 to about 40 gsm.

15 . The single-ply tissue product of any one of claims 11 through 14 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 any one of claims 11 through 15 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 any one of claims 11 through 16 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 any one of claims 11 through 17 wherein the single-ply tissue web comprises an uncreped through-air dried web.

19 . A single-ply tissue product having a sheet bulk greater than about 21 cc/g, a GMT from about 2200 to about 2700 g/3″, a GM Stretch greater than about 12 percent and a Stiffness Index less than about 5.0.

20 . The single-ply tissue product of claim 19 spirally wound into a roll, the roll having a Roll Bulk greater than about 17.0 cc/g.
