发明名称 TEMPORARY WET STRENGTH AGENTS AND PRODUCTS MADE FROM SUCH AGENTS
摘要 The invention relates to a tissue product comprising (a) tissue fibrous web incorporated throughout the tissue product; (b) a temporary wet strength agent capable of forming hemi-acetal bonds with the fibers of the web to prevent immediate degradation of the web when the tissue product contacts water; and (c) a composition containing a degrading agent selected from the group consisting of alkaline agents, oxidizing agents, nucleophilic agents, and combinations thereof; such that the tissue product has at least one surface and the degrading agent is located substantially throughout the surface of the fibrous web in an amount sufficient to make the fibrous web exhibit (i) an immediate wet tensile strength of at least 90% of the wet strength as compared to a web that does not contain a degrading agent and (ii) a wet soak decay that is at least a ten point improvement as compared to a tissue fibrous web that does not contain a degrading agent. The invention also relates to compositions for making the product, methods for making the composition, and methods for using the composition.
