Description
Unbleached pulps prepared by the kraft digestion of sulfite knotter rejects were bleached by two multiple-stage methods. One method (I) consisted of chlorination, alkali extraction, and hypochlorite oxdition stages; the other method (II) consisted of hypochlorite oxidation, chorination, alkali extraction, and hypochlorite oxidation stages. The bleached pulps were then tested for chemical and physical properties. In general, these bleached pulps were of high purity and showed a high degree of brightness. The alpha-cellulose content was from 85 to 95%. The pulps bleached by Method I were somewhat inferior in brightness to the pulps bleached by Method II, but had a greater alpha-cellulose content than the latter pulps. From the data for alpha-cellulose content and other data obtained by additional experiments, it is considered that the pulps bleached by Method I can be used for making various grades of paper.
