摘　　要：实验研究D1ED2漂白程序中ClO2用量、初始pH值和漂白温度对棉短绒浆粕漂白性能和浆粕聚合度的影响。实验所得较适宜的漂白工艺条件为:D1段ClO2用量1%,温度70℃,时间120 min,浆浓8%,初始pH值4;E段NaOH用量2%,温度70℃,时间90 min,浆浓8%;D2段ClO2用量1%,温度70℃,时间120 min,浆浓8%,初始pH值4。此漂白条件下棉浆粕白度可达82%ISO以上,聚合度略有降低。Effects of CIO2 dosage, initial pH value and bleaching temperature on bleaching properties and degree of polymerization of cotton linter pulp in D^ED2 bleaching sequence were carried out. The results showed that the optimal conditions ofD1ED2 bleaching sequence were： 1% of CIO2 dosage, 70℃, 120 min, 8% of pulp consistence and 4 of initial pH in D1 stage; 2% of NaOH dosage, 70%：, 90 rain and 8% of pulp consistence in E stage; 1% of CIO2 dosage, 70℃, 120 rain, 8% of pulp consistence and 4 of initial pH in D2 stage. In which 82%ISO of brightness of cotton hnter pulp was obtained and degree of polymerization decreased slightly
