Abstract

A method of controlling deposits on papermaking surfaces or fabrics on paper machines includes applying a deposition control solution to the papermaking surfaces or fabrics to inhibit deposition of organic contaminants therein. The deposition control solution comprises at least one cationic polymer, at least one at least one phthalate/glycol or polyethylene terephthalate/polyoxyethylene terephthalate (PET:POET) or polyalkylene terephthalate/polyoxyethylene terephthalate (PAT:POET) based copolymer, and at least one non-ionic surfactant in combination to provide improved deposition control.
