Abstract
It has now been discovered that the ratio of the wet tensile strength to the dry tensile strength of a tissue web, and more particularly a creped tissue web, can meet or exceed satisfactory levels without the excess use of a wet strength resin. For example, by treating the tissue making furnish with less than about 3 kilograms of wet strength resin per ton of furnish, forming the tissue web, and then creping the tissue web with a creping composition comprising a non-fibrous olefin polymer and a dispersing agent, a tissue web having a CD Wet/Dry ratio greater than about 0.30 may be produced. This discovery provides the flexibility to produce a tissue product with increased wet strength while reducing the add-on of wet strength agent.
