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 (18)

1. A rolled tissue product comprising a spirally wound, embossed, multi-ply tissue web having a first outer surface comprising a plurality of embossments and a non-crosslinked latex polymer disposed thereon and a second outer surface comprising a non-crosslinked latex polymer disposed thereon, the product having a basis weight from about 45 to about 60 gsm, a GMT from about 700 to about 1,700 g/3″, a Stiffness Index from about 4.0 to about 6.0 and a Slosh time less than about 2 minutes.

2. The rolled tissue product of claim 1 having a wet CD tensile from about 110 to about 160 g/3″.

3. The rolled tissue product of claim 1 having a Wet/Dry Ratio from about 0.10 to about 0.15.

4. The rolled tissue product of claim 1 having a Durability Index of about 15.0 or greater.

5. The rolled tissue product of claim 1 having a Slosh time from about 15 to about 45 seconds and a wet burst strength from about 150 to about 200 gf.

6. A creped, multi-ply tissue product comprising:

a. a first and a second tissue ply;

b. a creping composition consisting essentially of a non-crosslinked vinyl acetate-ethylene polymer and optionally an anti-blocking agent disposed on the first and the second tissue ply;

c. at least one softening composition selected from the group consisting of a polyhydroxy compound having a molecular weight of at least about 1,000 g/mol, a diamidoamine quaternary compound, an ester quaternary compound, an alkoxy alkyl quaternary compound, a benzyl quaternary compound, an alkyl quaternary compound, an imidazolinium quaternary compounds, a polysiloxane and glycerin disposed on the first or the second tissue ply; and

d. a plurality of embossments disposed on the first or the second tissue ply,

wherein the product has a GMT from about 700 to about 1,700 g/3″, a Stiffness Index from about 4.0 to about 6.0 and a Slosh time less than about 2 minutes.

7. The creped, multi-ply tissue product of claim 6 having a Durability Index from about 10.0 to about 20.0.

8. The creped, multi-ply tissue product of claim 6 wherein the creping composition comprises an anti-blocking agent selected from the group consisting of surfactants, silicones, waxes and polysaccharides.

9. The creped, multi-ply tissue product of claim 6 wherein the vinyl acetate-ethylene polymer is carboxylated.

10. The creped, multi-ply tissue product of claim 6 having a wet CD tensile from about 110 to about 160 g/3″.

11. The creped, multi-ply tissue product of claim 6 having a Wet/Dry Ratio from about 0.10 to about 0.15.

12. The creped, multi-ply tissue product of claim 6 having a Durability Index from about 15.0 to about 20.0.

13. The creped, multi-ply tissue product of claim 6 having a Slosh time less than about 60 seconds and a wet burst strength from about 150 to about 200 gf.
