Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A two-ply, through air dried tissue comprising an outer surface having at least one of an Average Peak to Valley Waviness of 140 microns or less or an Average Primary Amplitude of 50 microns or less. 2. The two-ply, through air dried tissue of claim 1 , wherein the outer surface has an Average Peak to Valley Waviness of 140 microns or less and a Waviness Uniformity of 27 microns or less. 3. The two-ply, through air dried tissue of claim 1 , wherein the outer surface has an Average Primary Amplitude of 50 microns or less and an Amplitude Uniformity of 8 microns or less. 4. A through air dried tissue having a bulk softness of less than 10TS7 and comprising an outer surface having an Average Peak to Valley Waviness of 140 microns or less. 5. The through air dried tissue of claim 4 , wherein the outer surface has a Waviness Uniformity of 27 microns or less. 6. A through air dried tissue having a bulk softness of less than 10TS7 and comprising an outer surface having an Average Primary Amplitude of 50 microns or less. 7. The through air dried tissue of claim 6 , wherein the outer surface has an Amplitude Uniformity of 8 microns or less. 8. A two-ply, 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. 9. The two-ply, through air dried tissue of claim 8 , wherein the tissue has a bulk softness of less than 10TS7. 10. The two-ply, through air dried tissue of claim 8 , wherein the outer surface has an Average Peak to Valley Waviness of 135 microns or less. 11. The two-ply, through air dried tissue of claim 8 , wherein the tissue has a lint value of 7.5 or greater. 12. The two-ply, through air dried tissue of claim 8 , wherein the tissue has a softness of at least 90. 13. The two-ply, through air dried tissue of claim 8 , wherein the tissue has a caliper of less than 650 microns.
