综述了臭氧对非木材纤维纸浆的漂白和改性作用机理及研究进展。主要介绍了臭氧对稻麦草浆、蔗渣浆、竹浆和棉、麻纤维等非木材纤维作用前后纤维形态及性能的变化及臭氧处理前后废水中污染物含量变化等方面的研究进展,并对臭氧在非木材纤维漂白和改性方面的新进展及应用前景进行了总结与展望。

Review on the Study Progress of Ozone Treatment in Bleaching and Modifications of Non-wood Fibers

In this article, research progress on the mechanisms of bleaching and modification of non-wood pulp fibers were reviewed. Herein, the study progress on the changes of fiber properties, such as fiber morphology, viscosity, brightness, crystallinity and lignin content of non-wood fibers (e.g., straw fibers, bagasse fibers, bamboo pulp fibers, cotton and jute fibers) before and after ozone treatment were mainly reviewed. In addition, the study progress on the changes of pollutants content in waste water from the ozone treatment of non-wood fibers was also reviewed. At last, the new development and application of ozone treatment in bleaching and modification of non-wood fibers were also summarized.
