Abstract

The novel tissue products of the present invention are generally produced by calendering a tissue basesheet using at least one patterned roll. In one embodiment the patterned roll replaces the flat steel roll commonly used in calendering. The elements on the patterned roll provide a means of providing a nip having variable loading that yields a web having a smooth surface without subjecting the web to excessive compression forces and preventing excessive caliper loss. Thus, webs converted according to the present invention have comparable or better surface smoothness compared to webs converted using conventional calendering means and also retain a greater percentage of their caliper and bulk.

First claim

What is claimed is:

1. A rolled tissue product comprising a calendered tissue web spirally wound into a roll, the calendered tissue web having a cross-machine direction (CD) stretch from about 8 to about 12 percent a Surface Smoothness less than about 0.260 and a Sheet Bulk greater than about 15 cc/g.

2. The rolled tissue product of claim 1 wherein the calendered tissue web has a Surface Smoothness from about 0.180 to about 0.260 and a Sheet Bulk from about 16 to about 24 cc/g.

3. The rolled tissue product of claim 1 wherein the calendered tissue web has an average MMD from about 0.014 to about 0.020.

4. The rolled tissue product of claim 1 wherein the calendered tissue web has a geometric mean tensile (GMT) from about 1750 to about 2750 g/3″.

5. The rolled tissue product of claim 1 wherein the calendered tissue web has a caliper from about 640 to about 700 μm.

6. The rolled tissue product of claim 1 wherein the calendered tissue web has a basis weight from 30 to 40 grams per square meter (gsm) and a caliper from about 610 to about 660 μm.

7. The rolled tissue product of claim 1 wherein the product has a roll firmness from about 5.0 to about 7.0.

8. The rolled tissue product of claim 1 wherein the product has a Roll Structure greater than about 1.80.

9. The rolled tissue product of claim 1 wherein the product has a roll bulk from about 16 to about 22 cc/g and a roll firmness from about 5.0 to about 7.0 mm.

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