The ratio of the wet tensile strength to the dry tensile strength of uncreped throughdried tissues and towels can be increased by treating the papermaking pulp with a debonder, a wet strength agent and a dry strength agent. The properties of the resulting product can be manipulated to either provide a product with normal degree of softness (as measured by the machine direction sheet stiffness) and a high wet strength, or a normal degree of wet strength and a higher degree of softness. |
