Abstract

A multi-layer through air dried tissue including a first exterior layer comprised substantially of hardwood fibers, an interior layer comprised substantially of softwood fibers, and a second exterior layer comprised substantially of hardwood fibers. The interior layer includes a first wet end additive comprising an ionic surfactant and a second wet end additive comprising a non-ionic surfactant.

Claims (21)

1. A through air dried tissue comprising an outer surface having an Average Peak to Valley Waviness of 140 microns or less, a Waviness Uniformity of 27 microns or less, an Average Primary Amplitude of 50 microns or less and an Amplitude Uniformity of 8 microns or less.

2. The tissue of claim 1 , wherein the tissue includes first and second exterior layers.

3. The tissue of claim 2 , further comprising an interior layer.

4. The tissue of claim 1 , wherein the tissue has a bulk softness of less than 10TS7.

5. The tissue of claim 1 , wherein the outer surface has an Average Peak to Valley Waviness of 135 microns or less.

6. The tissue of claim 1 , wherein the tissue has a lint value of 7.5 or greater.

7. The tissue of claim 1 , wherein the tissue has a softness of at least 90.

8. A multi-ply sheet comprising two or more plies, at least one of the two or more plies comprising the tissue of claim 1 .

9. The multi-ply sheet of claim 8 further comprising another one of the two or more plies comprising a tissue comprising an outer surface having an Average Peak to Valley Waviness of 140 microns or less, a Waviness Uniformity of 27 microns or less, an Average Primary Amplitude of 50 microns or less and an Amplitude Uniformity of 8 microns or less.

10. A multi-layer tissue comprising an outer surface having an Average Peak to Valley Waviness of 140 microns or less, a Waviness Uniformity of 27 microns or less and an Amplitude Uniformity of 8 microns or less.

11. The tissue of claim 10 , wherein the outer surface has an Average Primary Amplitude of 50 microns or less.

12. The tissue of claim 10 , wherein the tissue has a bulk softness of less than 10TS7.

13. The tissue of claim 10 , wherein the outer surface has an Average Peak to Valley Waviness of 135 microns or less.

14. A multi-ply sheet comprising two or more plies, at least one of the two or more plies comprising the tissue of claim 10 .

15. The multi-ply sheet of claim 14 further comprising another one of the two or more plies comprising a tissue comprising an outer surface having an Average Peak to Valley Waviness of 140 microns or less, a Waviness Uniformity of 27 microns or less, an Average Primary Amplitude of 50 microns or less and an Amplitude Uniformity of 8 microns or less.

16. A tissue comprising first and second exterior layers, the first exterior layer comprising an outer surface having an Average Peak to Valley Waviness of 140 microns or less and a Waviness Uniformity of 27 microns or less.

17. The tissue of claim 16 , further comprising an interior layer.

18. The tissue of claim 16 , wherein the outer surface has an Average Peak to Valley Waviness of 135 microns or less.

19. A multi-ply sheet comprising two or more plies, at least one of the two or more plies comprising the tissue of claim 16 .

20. A multi-ply sheet comprising two or more plies, at least one of the two or more plies comprising the tissue of claim 17 .

21. A through air dried tissue comprising an outer surface having at least two of the following: an Average Peak to Valley Waviness of 140 microns or less, a Waviness Uniformity of 27 microns or less, an Average Primary Amplitude of 50 microns or less and an Amplitude Uniformity of 8 microns or less.
