Abstract

Disclosed are non-treated, creped tissue webs, and tissue products produced therefrom, having low stiffness and surface lint. The inventive products may be produced by a print creping process adapted to dispose a non-crosslinked latex polymer on at least one of the outer surfaces of the tissue product. The non-crosslinked latex polymer creping composition does not negatively affect stiffness such that the products generally have a Stiffness Index less than about 5.0, such as from about 2.5 to about 5.0.

Claims (24)

1. A non-treated and creped multi-ply tissue product comprising:

a. a first creped, non-treated, through-air dried tissue ply;

b. a second creped, non-treated, through-air dried tissue ply;

c. a creping composition disposed on the first and the second tissue plies; and

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

wherein the product is devoid of a permanent wet strength agent and has a geometric mean tensile strength (GMT) from about 1,000 to about 2,500 g/3″, a Wet/Dry Ratio from about 0.100 to about 0.200 and a geometric mean tensile energy absorption (GM TEA) from about 20 gf·cm/cm 2 to about 40 gf·cm/cm 2 .

2. The tissue product of claim 1 having a GMT from about 1,000 to about 2,200 g/3″.

3. The tissue product of claim 1 having a GMT from about 1,500 to about 2,200 g/3″.

4. The tissue product of claim 1 having a Stiffness Index from about 2.5 to about 5.0.

5. The tissue product of claim 1 having a geometric mean slope (GM Slope) about 5.0 to about 10.0 kg.

6. The tissue product of claim 1 having a GM Slope from about 5.0 to about 8.0 kg.

7. The tissue product of claim 1 having a GM TEA from about 25 to about 45 gf·cm/cm2.

8. The tissue product of claim 1 having a TEA Index from about 1.50 to about 2.25.

9. The tissue product of claim 1 having a Slosh Time less than about 2 minutes.

10. The tissue product of claim 1 having a basis weight from about 48.0 to about 60.0 gsm.

11. The tissue product of claim 1 having a Wet/Dry Ratio from about 0.100 to about 0.175.

12. The tissue product of claim 1 having a wet CD tensile strength from about 120 to about 200 g/3″ and a Wet/Dry Ratio from about 0.100 to about 0.175.

13. The tissue product of claim 1 havnig a Slough less than about 5.0 mg.

14. The tissue product of claim 1 havnig a dry burst strength greater than about 700 gf.

15. The tissue product of claim 1 havnig a geometric mean stretch (GM Stretch) greater than about 20 percent.

16. The tissue product of claim 1 wherein the creping composition comprises a carboxyl-functional latex polymer.

17. The tissue product of claim 1 wherein the creping composition comprises a non-crosslinked vinyl acetate-ethylene polymer.

18. The tissue product of claim 1 wherein the first ply or the second ply comprises a temporary wet strength agent.

19. The tissue product of claim 18 wherein the temporary wet strength agent comprises a glyoxalated polyacrylamide polymer.
