Abstract

A process for bleaching a cellulose pulp consisting of: A) treating said paste in aqueous suspension with at least one compound selected from the group consisting of chlorine and chlorine dioxide, to solubilize the non-cellulosic materials associated with said cellulose pulp and then B) treating said paste to a weight consistency of 3 to 15% by hypochlorination with about 0.5 to 3.0% hypochlorite, calculated on the weight of the dried pasta, at a temperature comprised between approximately 75º and 160º f (24º c) and 71º c), at a ph of 7 to 9 about 7 for 15 to 180 minutes C) optionally, try again with chlorine dioxide.
