Abstract
A chemically enhanced paper structure having a discrete pattern of a chemical composition is disclosed. The paper structure comprises a cellulose substrate, such as tissue paper. The substrate has a topography comprising at least two different elevations. The chemical composition may include a chemical softener composition or a surface-active composition and is selectively disposed in register with one of the elevations of the cellulose substrate, preferably the higher elevation regions. The paper structure is suitable for use as bath tissue or facial tissue.
Claims29
A chemically enhanced paper structure comprising:
- a macroscopically monoplanar cellulosic substrate having two elevations, a first elevation defining a first pattern and a second elevation defining a second pattern, said second pattern comprising a plurality of discrete domes extending outwardly from said first elevation, wherein each said elevation comprises one or more regions;
- and
- an immobilized chemical papermaking additive disposed on one of said regions corresponding to one of said elevations of said cellulosic substrate, said regions of said other elevation being free of said additive.
A through-air-dried chemically enhanced paper structure comprising:
- a macroscopically monoplanar cellulosic substrate comprising an essentially continuous network region and discrete regions disposed therein, said discrete regions extending outwardly from said essentially continuous network region, said essentially continuous network defining a first elevation and said discrete regions defining a second elevation;
- and
- an immobilized chemical papermaking additive disposed on one of said regions corresponding to one of said elevations of said cellulosic substrate, said regions of said other elevation being free of said additive.
