Abstract

A tissue product including a laminate of at least two plies of a multi-layer tissue web, the tissue product having a softness value (HF) of 92.0 or greater, a lint value of 4.5 or less, and an Sdr of greater than 3.0.

Claims (23)

1. A structured tissue product comprising:

a laminate of at least two plies of a multi-layer tissue web, the tissue product having a softness value (HF) of 84 to 94, a lint value of 1.8 to 4.3, and an Sdr of 3.2 to 3.4.

2. The structured tissue product of claim 1 , wherein the tissue product has a bulk softness of less than 9 TS7.

3. The structured tissue product according to claim 1 , wherein the multi-layer tissue web comprises: a first exterior layer; an interior layer; and a second exterior layer.

4. The structured tissue product according to claim 3 , wherein the first exterior layer comprises at least 50% virgin hardwood fibers.

5. The structured tissue product according to claim 3 , wherein the first exterior layer comprises at least 75% virgin hardwood fibers.

6. The structured tissue product according to claim 4 , wherein the virgin hardwood fibers is virgin eucalyptus fibers.

7. The structured tissue product according to claim 3 , wherein the interior layer contains a first wet end additive comprising an ionic surfactant and a second wet end additive comprising a non-ionic surfactant.

8. The structured tissue product according to claim 3 , wherein the first exterior layer comprises a wet end dry strength additive.

9. The structured tissue product according to claim 8 , wherein the wet end dry strength additive comprises a graft copolymer composition of a vinyl monomer and a functionalized vinyl amine-containing base polymer.

10. The structured tissue product according to claim 3 , wherein the second exterior layer comprises a wet end dry strength additive.

11. The structured tissue product according to claim 10 , wherein the wet end dry strength additive comprises a graft copolymer composition of a vinyl monomer and a functionalized vinyl amine-containing base polymer.

12. The structured tissue product according to claim 7 , wherein the second wet end additive comprises an ethoxylated vegetable oil.

13. The structured tissue product according to claim 7 , wherein the second wet end additive comprises a combination of ethoxylated vegetable oils.

14. The structured tissue product according to claim 7 , wherein the ratio by weight of the second wet end additive to the first wet end additive in the tissue is at least eight to one.

15. The structured tissue product according to claim 7 , wherein the ratio by weight of the second wet end additive to the first wet end additive in the tissue is at most ninety to one.

16. The structured tissue product according to claim 7 , wherein the ionic surfactant comprises a debonder.

17. The structured tissue product according to claim 3 , wherein the first and second exterior layers are substantially free of surface deposited softener agents or lotions.

18. The structured tissue product according to claim 3 , wherein the first exterior layer comprises a surface deposited softener agent or lotion.

19. The structured tissue product according to claim 7 , wherein the non-ionic surfactant has a hydrophilic-lipophilic balance of less than 8.

20. The structured tissue product of claim 1 , wherein the tissue product has an MD tensile strength and CD tensile strength of at least 50 N/m and a basis weight of less than 40 gsm.

21. The structured tissue product of claim 1 , wherein each of the at least two plies comprises embossed areas, wherein the embossed area occupy between 3% to 15% of the total surface area of a surface of the ply.

22. The structured tissue product of claim 1 , wherein the tissue product is one of sanitary, bath or facial tissue.
