    • 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.
    • 包括具有离子表面活性剂和非离子表面活性剂的内层的多层通过空气干燥的组织作为湿端添加剂引入。 组织制造方法通过空气干燥而不损害所得组织的柔软度和清洁能力。 制造方法避免了与湿末添加剂相关的缺点,特别是避免使用大量的添加剂来获得对所得组织的期望效果。 多层通过空气干燥的组织包括第一外层,内层和第二外层,所述内层包括包含离子型表面活性剂的第一湿末添加剂和包含非离子表面活性剂的第二湿末添加剂。 组织表现出改善的表面轮廓,提供改善的产品一致性和较少的断裂片材缺陷。 组织粗糙度的特征在于平均初级幅度和平均峰谷谷波纹。
