Abstract

A method for improving RDF aids efficacy, paper machine performance and sheet properties formed during a papermaking process is disclosed. The methodology includes the following steps: (a) applying one or more RDF aids to the papermaking process to a point between after the headbox and on or before the first drainage element of a papermaking process.
