1. A paper product, comprising:
a plurality of pulp fibers and an at least partially cured resin system, wherein the resin system, prior to curing, comprises a first polyamidoamine-epihalohydrin resin and a second resin comprising a second polyamidoamine-epihalohydrin resin, a urea-formaldehyde resin, or a mixture thereof, and wherein the resin system, prior to curing, comprises greater than 30 wt % to about 80 wt % of the second resin, based on a combined solids weight of the first polyamidoamine-epihalohydrin resin and the second resin. |
