The effects of pre-treatment and consistency on treatment time and brightness of bagasse alkaline peroxide mechanical pulp

Preparation and pre-treatment of raw material influences the pulp production time and color elimination. Pulp consistency during the treatment also influences the color reaction. In the preparation of the APMP pulp, bagasse was pretreated by either boiling water, 1% NaOH as well as 1% NaOH + 1% H2O...
