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.
Claims13
A chemically enhanced paper structure comprising:
- a cellulosic substrate having first regions of relatively high density and second regions of relatively low density, said regions of relatively high density and relatively low density each being disposed in a non random, repeating pattern;
- and
- an immobilized chemical papermaking additive disposed on one of said regions of said relatively high density or one of said regions of relatively low density, the other of said regions being free of said chemical papermaking additive.
A chemically enhanced paper structure comprising:
- a cellulosic substrate having first regions comprising an essentially continuous high density network and second discrete regions of low density;
- and
- an immobilized chemical papermaking additive disposed on said low density regions, said high density regions being free of said chemical papermaking additive.
A through air-dried chemically enhanced paper structure comprising:
- a cellulosic substrate comprising an essentially continuous high density network region, and discrete low density regions disposed therein, said relatively high density essentially continuous network region and said relatively low density discrete regions each being disposed in a non random repeating pattern, wherein said relatively high density essentially continuous network region defines a first elevation and said relatively low density discrete regions defines a second elevation;
- and
- an immobilized chemical papermaking additive disposed on one of said regions of relatively high density or one of said regions of relatively low density, the other of said regions being free of said chemical papermaking additive.
