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 (20)

1. A 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 92.0 or greater, a lint value of 4.5 or less, and an Sdr of greater than 3.0.

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

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

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

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

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

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

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

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

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

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

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

17. The 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.

18. The 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.

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

20. The tissue product of claim 1 , wherein the tissue product has a softness value (HF) of 93.0 or greater, a lint value of 4.3 or less, and an Sdr of greater than 3.0.
