Abstract

Disclosed are multi-ply tissue products comprising a non-crosslinked binder that are durable and dispersible. The products generally have a Slosh time less than 2 minutes, such as less than about 60 seconds, such as less than about 45 seconds. Surprisingly, the foregoing Slosh times are achieved despite the tissue products having relatively high cross-machine direction (CD) wet tensile strength, such as greater than about 100 g/3″. Typically, increasing wet tensile strength, particularly wet CD tensile strength, negatively effects dispersability and increases Slosh time. Despite this trend, the present invention surprisingly provides a tissue product having a relatively high degree of wet strength and good dispersability.

Claims (10)

1. A creped, multi-ply tissue product comprising a first creped tissue ply and a second creped tissue ply, the first and second creped tissue plies comprising fibers selected from the group consisting of hardwood fibers, softwood fibers and combination thereof the product having a geometric mean tensile strength (GMT) greater than about 700 g/3″, a Stiffness Index from about 4.0 to about 6.0, a Durability Index of about 10.0 or greater and a Slosh time less than about 2 minutes.

2. The creped, multi-ply tissue product of claim 1 having a GMT from about 700 to about 1,700 g/3″.

3. The creped, multi-ply tissue product of claim 1 having a GM TEA greater than about 14.5 g·cm/cm 2 .

4. The creped, multi-ply tissue product of claim 1 having a GM TEA from about 20 to about 30 g·cm/cm 2 .

5. The creped, multi-ply tissue product of claim 1 having a TEA Index greater than about 1.50.

6. The creped, multi-ply tissue product of claim 1 having a wet burst strength of about 1,000 gf or greater.

7. The creped, multi-ply tissue product of claim 1 having a Slosh time from about 20 to about 120 seconds.

8. The creped, multi-ply tissue product of claim 1 having a basis weight from about 45 to about 60 grams per square meter (gsm) and a sheet bulk greater than about 8.0 cubic centimeters per gram (cc/g).

9. The creped, multi-ply tissue product of claim 1 having a wet CD tensile greater than about 100 g/3″.

10. The creped, multi-ply tissue product of claim 1 having a Wet/Dry Ratio from about 0.10 to about 0.15.
