Abstract
Embodiments are directed to methods for inhibiting contaminants formation during papermaking operation. The method includes preparing an aqueous solution having a pH greater than 7.0 and comprising peroxide; and applying the aqueous solution onto or within one or more of forming wires, press felts and woven through air drying (TAD) belts prior to contacting and transporting a wet paper web to inhibit the formation of wet paper web contaminants onto the surfaces of or within the forming wires, press felts and woven TAD belts.
