Abstract: Methods of producing a multi-ply paper product are provided. The methods comprise applying coagulant and/or hybrid coagulant-flocculant composition to an upper ply substrate disposed adjacent and above a lower ply substrate in an amount such that a portion of the coagulant and/or the hybrid coagulant-flocculant composition passes through the upper ply substrate. Preferably, the lower ply substrate has a greater freeness than the upper ply substrate. The methods of the present disclosure preferably allow for efficient use of RDF chemicals while making use of the innate freeness differences between the upper and lower ply substrates.

Abstract: The disclosure relates to methods and compositions for enhancing the performance of a sizing agent in a papermaking process using a sizing agent enhancer. The sizing agent can be emulsified with an emulsifier and the sizing enhancer can be a polymer comprising at least one primary or secondary amine containing monomer. The method can comprise emulsifying the sizing agent with the emulsifier; and thereafter adding the emulsified sizing agent and the sizing enhancer, separately from or contemporaneously with the emulsified sizing agent, to a fiber furnish of a papermaking process. The combination of the emulsified sizing agent and the sizing enhancer improves the sizing of product paper over the use of the sizing agent without the sizing enhancer. In at least some embodiments, the emulsified sizing agent is ASA emulsified with a polymer comprising at least one primary or secondary amine containing monomer and the sizing enhancer comprises a diallylamine-acrylamide copolymer.
