Abstract
A multi-ply through air dried structured tissue having a bulk softness of less than 10 TS7 and a lint value of 5.0 or less. Each ply of the tissue has a first exterior layer that includes a wet end temporary wet strength additive in an amount of approximately 0.25 kg/ton and a wet end dry strength additive in an amount of approximately 0.25 kg/ton, an interior layer that includes a first wet end additive comprising an ionic surfactant, and a second wet end additive comprising a non-ionic surfactant, and a second exterior layer.

A roll bath tissue comprising:
- a laminate of at least two plies of a multi-layer through air dried tissue, each ply comprising a first exterior layer, an interior layer and a second exterior layer, the roll bath tissue having a bulk softness of less than 10 TS7, a lint value of 5.0 or less, an Average Peak to Valley Waviness of 140 microns or less, a waviness uniformity of 27 microns or less, and a caliper greater than 510 microns/2 ply, wherein the first and second exterior layers are substantially free of any surface-deposited softener agents or lotions.
A roll bath tissue comprising:
- a laminate of at least two plies of a multi-layer through air dried tissue, each ply comprising a first exterior layer, an interior layer and a second exterior layer, the roll bath tissue having a bulk softness of 8.2 to 10 TS7, a lint value of 5.0 or less, an Average Peak to Valley Waviness of 140 microns or less, and an Average Primary Amplitude of 50 microns or less, wherein the first and second exterior layers are substantially free of any surface-deposited softener agents or lotions.
A roll bath tissue comprising:
- a laminate of at least two plies of a multi-layer through air dried tissue, each ply comprising a first exterior layer, an interior layer and a second exterior layer, the roll bath tissue having a softness of greater than 90 Hand Feel (HF), a lint value of 5.0 or less, an Average Peak to Valley Waviness of 140 microns or less, and an Average Primary Amplitude of 50 microns or less, wherein the first and second exterior layers are substantially free of any surface-deposited softener agents or lotions.
