Abstract

La presente invención se refiere a métodos para preparar pastas papeleras con brillantez premium o casi premium para aplicaciones de toallas y papel tisú a partir de fuentes de fibra que comprenden cantidades sustanciales de pasta papelera que contiene lignina y pasta papelera química que controla finos, incrustaciones y residuos aniónicos Estos métodos utilizan hidróxido alcalino en combinación con peróxido y oxígeno para las fases de blanqueo inicial seguidas por el tratamiento con un agente de activación de peróxido para convertir peróxido residual en la pasta papelera en ácido peracético seguido por una fase de blanqueo reductivo final
