High temperature peroxide bleaching of mechanical pulps

A method of making bleached mechanical pulps is disclosed for pulping mills having a primary and a secondary refiner. A first step (100) is to provide cellulosic materials, such as wood chips to refine into the pulp; the wood chips have an initial brightness level. A second step (102) is to provide...
