Abstract

In Kraft pulping, about 90–95 % of wood lignin gets solubilized during the cooking process. The remaining 5–10 % of lignin is responsible for the brown color of the Kraft pulp and unbleached paper. The objective of bleaching is to remove the residual lignin from the pulp as selectively as possible, without degrading the pulp carbohydrate, especially cellulose, which would lead to a decrease in strength of the pulp.
