Abstract

Disclosed am multi-ply tissue products, particularly creped and through-air dried facial tissue products, having improved strength and softness. For example, the products have a geometric mean tensile strength (GMT) greater than about 1,2000 g/3″, a geometric mean tensile energy absorption (GM TEA) of about 20 g·cm/cm 2 or greater and a TS7 value less than about 16.0. In certain instances, the tissue products also have a low degree of stiffness and a relatively smooth surface, such as a Stiffness Index less than about 8.00 and a TS750 value less than about 15.0. The tissue products may be prepared from webs manufactured by a print-crepe process that deposits a latex polymer on at least one of the outer surfaces of the tissue web.

First claim

What is claimed is:

1. A multi-ply tissue product comprising a first creped through-air dried tissue ply having a first and a second outer surface and a latex polymer disposed on the first outer surface and a second creped through-air dried tissue ply having a first and a second outer surface and a latex polymer disposed on the first outer surface, the first and second tissue plies plied together in facing arrangement such that the first outer surfaces of the first and second plies face one another, the product having a geometric mean tensile strength (GMT) greater than about 1,200 g/3″ and a TS7 value less than about 16.0.

2. The product of claim 1 having a Stiffness Index less than about 8.0.

3. The product of claim 1 wherein the latex polymer is a non-crosslinked vinyl acetate-ethylene polymer.

4. The product of claim 1 having a GMT from about 1,400 to about 2,000 g/3″.

5. The product of claim 1 having TS7 from about 10.0 to about 15.0.

6. The product of claim 1 having TS750 from about 8.0 to about 15.0.

7. The product of claim 1 having a geometric mean stretch (GM Stretch) greater than about 20 percent.

8. The product of claim 1 having a TEA Index of about 1.75 or greater.

9. The product of claim 1 having a GM TEA greater than about 20.0 g·cm/cm 2 .

10. The product of claim 1 having a CD Stretch greater than about 15 percent.

11. The product of claim 1 having a Wet/Dry Ratio greater than about 0.30.

12. The product of claim 1 having a basis weight from about 35 to about 60 grams per square meter (gsm) and a sheet bulk greater than about 8.0 cubic centimeters per gram (cc/g).

13. The product of claim 1 having a GM Slope less than about 10.0 kg.

14. The product of claim 1 wherein the first and second tissue plies are through-air dried.
