| titleOfInvention | High efficiency chlorine dioxide pulp bleaching process |
| abstract | The invention relates to a highly efficient process for technical cellulose bleaching, which makes it possible to produce lighter technical celluloses using the same amount of chlorine dioxide or just as clear using substantially reduced amounts of chlorine dioxide. This process involves reacting chlorine dioxide with technical cellulose at a pH between about 5 and 10 for about 5 to 40 minutes, then acidifying the mixture to make it reach a pH between about 1.9 and 4 , 2. The mixture is then reacted for at least about two hours to complete the two-step high / low pH bleaching process. |
