Abstract
A toilet tissue product may include a first cellulosic ply and a second cellulosic ply. Desirably, the first cellulosic ply further includes a single layer and the second cellulosic ply further includes a single layer. At least one ply may have a region that prevents fluid from striking through the tissue product.
Claims31
A toilet tissue product, comprising:
- a first cellulosic ply further comprising a single layer;
- a second cellulosic ply further comprising a single layer;
- and
- at least one ply having a region that minimizes fluid strikethrough, wherein the region is situated at an exterior surface of the tissue product when the first and second plies are overlaid one atop the other, wherein the tissue does not contain permanent wet strength binder materials, and wherein the region comprises a uniform coating of dried liquid repellent agent.

A toilet tissue product comprising:
- a first cellulosic ply having at least one layer;
- and
- a second cellulosic ply having at least one layer, wherein at least one exterior surface of the toilet tissue has a region that comprises a uniform coating of dried liquid repellent agent for minimizing fluid strikethrough, wherein the toilet tissue does not contain permanent wet strength binder materials.
A method of producing a toilet tissue product comprising the steps of:
- providing a first cellulosic ply further comprising a single layer;
- providing a second cellulosic ply further comprising a single layer;
- treating at least one ply with a liquid application repellent agent to create a region that minimizes fluid strikethrough;
- and
- overlaying the first and second plies one atop the other so that the region is situated at an exterior surface of the tissue product, and the tissue product does not contain permanent wet strength binder materials.
