Abstract
The present invention describes an additive which controls stickies formation and removes anionic trash from recycled old corrugated container furnish, old newsprint furnish, deinked pulp furnish, old magazine grade furnish, coated broke furnish, or thermomechanical pulp furnish. The present invention treats talc with either a tertiary or quaternary amine. The treated talc is then added to the pulp slurry and removes stickies by binding the stickies to the talc and neutralizes the anionic trash that may be present. The present invention also describes a method for modifying talc particles involving contacting a tertiary or quaternary amine with talc particles. The present invention further describes a talc created by the process of contacting a tertiary or quaternary amine with talc particles. The present invention additionally describes a paper product having a modified talc filler wherein the modified talc filler has been contacted with a tertiary or quaternary amine.
