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 (25)

1. A non-treated and creped multi-ply tissue product comprising a first non-treated and creped tissue ply and a second non-treated and creped tissue ply, wherein the first and the second non-treated and creped tissue plies are substantially free from a permanent wet strength agent, the non-treated and creped multi-ply tissue product having a geometric mean tensile (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 45 gf·cm/cm 2 .

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

3. The tissue product of claim 1 wherein the product has a Slough time less than about 5.0 mg.

4. The tissue product of claim 1 wherein the product has a dry burst strength greater than about 700 gf.

5. The tissue product of claim 1 wherein the product has a Stiffness Index less than about 5.0.

6. The tissue product of claim 1 wherein the product has a Stiffness Index from about 2.5 to about 5.0.

7. The tissue product of claim 1 wherein the product has a geometric mean slope (GM Slope) from about 5.0 to about 8.0 kg.

8. The tissue product of claim 1 wherein the product has a TEA Index greater than about 1.50.

9. The tissue product of claim 1 wherein the product has a geometric mean stretch (GM Stretch) greater than about 20 percent.

10. The tissue product of claim 1 wherein the product has a GM TEA from about 25 to about 40 gf·cm/cm2.

11. The product of claim 1 further comprising a plurality of embossments disposed on the first or the second non-treated and creped tissue plies.

12. The product of claim 1 wherein the first and the second non-treated and creped tissue plies are through-air dried.

13. The product of claim 1 wherein the product has a basis weight from about 48.0 to about 60.0 grams per square meter (gsm).

14. A rolled tissue product comprising a core and a multi-ply tissue product spirally wound about the core, the multi-ply tissue product comprising at least one non-treated and creped tissue ply having a first outer surface comprising a plurality of embossments and a non-crosslinked latex polymer disposed thereon, the multi-ply tissue product is devoid of a permanent wet strength agent and having a basis weight from about 48.0 to about 60.0 gsm, a 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 Slough time less than about 5.0 mg.

15. The rolled tissue product of claim 14 wherein the multi-ply tissue product has GM TEA from about 20 to about 45 gf·cm/cm 2 .

16. The rolled tissue product of claim 14 wherein the multi-ply tissue product has a Stiffness Index less than about 5.0.

17. The rolled tissue product of claim 14 wherein the multi-ply tissue product has a dry burst strength greater than about 700 gf.

18. The rolled tissue product of claim 14 wherein the outer surface of the at least one non-treated and creped tissue ply further comprises a polysaccharide or a surfactant.

19. The rolled tissue product of claim 14 wherein the multi-ply tissue product has a Slosh time less than about 2 minutes.

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

a. a first non-treated and creped tissue ply;

b. a second non-treated and creped tissue ply;

c. 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; and

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

wherein the product is devoid of a permanent wet strength agent and has a 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 Slosh time less than about 2 minutes.
