Blends of polymers as wet strengthening agents for paper

A method for making a paper product, comprising:

• contacting a plurality of pulp fibers with a resin system comprising a first polyamidoamine-epihalohydrin resin and a second resin comprising a second polyamidoamine-epihalohydrin resin, a urea-formaldehyde resin, or a mixture thereof to produce a paper product, wherein the first resin and the second resin are sequentially or simultaneously contacted with the plurality of pulp fibers, wherein the period for sequential addition between the first resin and the second resin is about 1 second to about 1 hour, and wherein the first polyamidoamine-epihalohydrin resin is made by reacting a polyamine with a functionally-symmetric cross-linker to produce a partially cross-linked polyamine, reacting an epihalohydrin with the partially cross-linked polyamine to produce a halohydrin-functionalized polymer, and cyclizing the halohydrin-functionalized polymer to produce the first polyamidoamine-epihalohydrin resin, wherein the first polyamidoamine-epihalohydrin has azetidium moieties.
