The resin system can include a first polyamidoamine-epihalohydrin resin and a second resin that can include a second polyamidoamine-epihalohydrin resin, a urea-formaldehyde resin, or a mixture thereof to produce a paper product. The first resin and the second resin can be sequentially or simultaneously contacted with the plurality of pulp fibers. The period for sequential addition between the first resin and the second resin is about 1 second to about 1 hour.

摘要： Methods for making composite products are provided. In at least one specific embodiment, the method can include combining a plurality of lignocellulose substrates and one or more free radical precursors to produce a mixture of the lignocellulose substrates and the one or more free radical precursors. The method can also include maintaining the mixture at a temperature less than 60° C. for at least 10 minutes while retaining at least 11 wt % of the one or more free radical precursors charged to the mixture. The method can then include heating the mixture comprising at least 11 wt % of the one or more free radical precursors charged to the mixture to a temperature of at least 60° C. to about 300° C. to produce a composite product. The composite product can have a density less than 1 g/cm3 and an internal bond strength of at least 0.35 MPa.

摘要： Wet strengthened fiber products, wet strengthening resins, and methods for making such wet strengthened fiber products and wet strengthening resins. The wet strengthened fiber product can include a fiber web and an at least partially cured wet strengthening resin, which prior to at least partially curing, the wet strengthening resin can include a polyamide-epihalohydrin (PAE) resin and a cationic styrene maleimide (SMI) resin. The PAE resin can include a reaction product of a polyamidoamine and an epihalohydrin and the cationic SMI resin can include a reaction product of a styrene maleic anhydride (SMA) copolymer and an amine. The wet strengthened fiber product can include the wet strengthening resin in an amount of about 0.05 wt % to about 5 wt %, based on a dried weight of the wet strengthened fiber product.
