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.

Claims (12)

1. A single-ply tissue web having a basis weight from about 35 to about 50 gsm, a GMT from about 700 to about 1400 grams per 76.2 mm sample width, a sheet bulk greater than about 12 cc/g and a Surface Smoothness S90 value less than about 105 μm.

2. The single-ply tissue web of claim 1 having a Stiffness Index from about 4 to about 8.

3. The single-ply tissue web of claim 1 having a geometric mean slope less than about 10,000 grams per 76.2 mm sample width.

4. The single-ply tissue web of claim 1 having a geometric mean stretch greater than about 10 percent.

5. The single-ply tissue web of claim 1 having a Surface Smoothness Sa value less than about 25 μm and a Surface Smoothness Sq value less than about 40 μm.

6. The single-ply tissue web of claim 1 wherein the single-ply tissue web comprises a through-air dried web.

7. The single-ply tissue web of claim 1 wherein the single-ply tissue web comprises an uncreped through-air dried web.

8. The single-ply tissue web of claim 1 wherein the sheet bulk is from about 12 to about 20 cc/g.

9. The single-ply tissue web of claim 1 wherein the sheet bulk is from about 14 to about 18 cc/g.

10. The single-ply tissue web of claim 1 wherein the sheet bulk is from about 14 to about 18 cc/g and the GMT is from about 800 to about 1,200 g/3″.

11. The single-ply tissue web of claim 10 having a geometric mean slope from about 4,000 to about 8,000 g/3″.

12. The single-ply tissue web of claim 10 having a geometric mean stretch from about 14 to about 18 percent.
