Abstract

Disclosed are multi-ply tissue products comprising a non-crosslinked binder that are durable, smooth and with low levels of Slough. In certain instances the creped tissue product have a geometric mean tensile (GMT) from about 700 to about 1,500 g/3″, a basis weight from about 45 to about 60 gsm and a Slough less than about 2.00 mg, more preferably less than about 1.50 mg, such as from about 0.10 to about 2.00, such as from about 0.25 to about 1.50 mg. The inventive tissue products also have good durability, such as a Durability Index from about 10.0 to about 20.0, smooth surfaces, such as a TS750 value from about 15.0 to 40.0 and low stiffness, such as a Stiffness Index less than about 10.0.

First claim

What is claimed is:

1. A creped, multi-ply tissue product comprising a first creped tissue ply and a second creped tissue ply, the product having a geometric mean tensile strength (GMT) from 700 to 1,700 g/3″, a Durability Index from 10.0 to 20.0, a Stiffness Index from 4.0 to 8.0 and a Slough from 0.25 to 2.00 mg.

2. The creped, multi-ply tissue product of claim 1 having a GMT from about 900 to about 1,500 g/3″.

3. The creped, multi-ply tissue product of claim 1 having a burst index greater than about 8.0.

4. The creped, multi-ply tissue product of claim 1 having a dry burst greater than about 1,000 gf.

5. The creped, multi-ply tissue product of claim 1 having a Slough from 0.25 to about 1.50 mg.

6. The creped, multi-ply tissue product of claim 1 having a basis weight from about 45 to about 60 grams per square meter (gsm).

7. The creped, multi-ply tissue product of claim 1 having a geometric mean slope from about 6.5 to about 8.5 kg.

8. The creped, multi-ply tissue product of claim 1 having a TEA Index from about 1.50 to about 2.25.

9. The creped, multi-ply tissue product of claim 1 having a TS750 value from about 15.0 to about 40.0.

10. The creped, multi-ply tissue product of claim 1 wherein each of the first and second creped tissue plies comprise fibers consisting essentially of wood pulp fibers.

11. The creped, multi-ply tissue product of claim 10 wherein the wood pulp fibers are softwood kraft pulp fibers, hardwood kraft pulp fibers, or a combination thereof.

12. The creped, multi-ply tissue product of claim 1 wherein each of the first and second creped tissue plies comprise a plurality of embossments disposed thereon.

13. The creped, multi-ply tissue product of claim 1 wherein each of the first and second creped tissue plies are through-air dried.

14. The creped, multi-ply tissue product of claim 1 wherein each of the first and second creped tissue plies have a first outer surface comprising a plurality of embossments and a non-crosslinked latex polymer disposed thereon.

15. The creped, multi-ply tissue product of claim 14 wherein the non-crosslinked latex polymer is a vinyl acetate-ethylene polymer.

16. The creped, multi-ply tissue product of claim 15 wherein the vinyl acetate-ethylene polymer is carboxylated.

17. The creped, multi-ply tissue product of claim 14 further comprising an anti-blocking agent selected from the group consisting of polysaccharides and surfactants disposed on the first outer surface.
