A multi-layer through air dried tissue including an interior layer having an ionic surfactant and a non-ionic surfactant, introduced as wet end additives. A tissue manufacturing method uses through air drying without compromising softness and cleaning ability of the resulting tissue. The manufacturing method avoids the disadvantages associated with wet end additives, and in particular avoids the use of a large amount of additive to achieve the desired effect on the resulting tissue. A multi-layer through air dried tissue comprises a first exterior layer, an interior layer and a second exterior layer the interior layer includes a first wet end additive comprising an ionic surfactant and a second wet end additive comprising a non-ionic surfactant. The tissue exhibits improved surface profile that provides for improved product consistency and fewer defects that break sheets. Roughness of tissue is characterized by Average Primary Amplitude and Average Peak to Valley Waviness. |
