Abstract
Tissue sheets are disclosed containing an additive composition. The additive composition is applied to the tissue sheet during a creping process in a controlled manner such that the additive composition forms deposits on the sheet separated by untreated areas. In one embodiment, the additive composition is applied to a creping surface. A wet tissue sheet is then transferred to the creping surface by a topographical surface containing elevations. The elevations press the tissue sheet against the creping surface. When creped from the surface, the additive compositions transfers to the tissue sheet according to where the elevations were located on the topographical surface.
