ABSTRACT:
The present invention provides for methods and compositions for removing stickies and pitch from papermaking fiber by first chemically treating the papermaking fiber with a composition of at least two of an oil-soluble or water-dispersible hydrophobic polymer, an oil soluble or water-dispersible surfactant having an HLB of about 1 to about 10, a tackifier, and an oil soluble or water-dispersible solvent then mechanically separating the agglomerated stickies and pitch from the papermaking fiber.
