以蝴蝶桉木纤维为原料，使用2，2，6，6 －四甲基哌啶-1- 氧化物自由基( TEMPO) /溴化钠( NaBr) /次氯酸钠( NaClO) 氧化体系对纤维进行氧化，通过纤维质量分析仪、动态滤水仪和显微镜等对氧化前后纤维的形态和浆料性能进行表征; 并将氧化后的浆料用于制备透明纸，研究了NaClO 用量对纸页性能的影响．结果表明: TEMPO 和 NaBr 用量一定时，随着NaClO 用量的增加，纤维的平均长度减小了0． 8mm，平均宽度增大了4．7μm，细小纤维含量增加 8 倍，纤维的卷曲指数值下降13．9 个百分点，滤水性能变差; 相比于原浆制备的透明纸，氧化浆制备的透明纸强度和弹性模量均增大，抗张指数最大可提高 4 倍，弹性模量最大可提高 6 倍，纸页表面粗糙度最大可降低73．0 %， 透明度高达 87 %．

In the investigation,the wood fibers from butterfly eucalyptus were oxidized in the 2,2,6,6- tetrameth-ylpiperidine-1- oxyradical (TEMPO) / NaBr/ NaClO oxidization system,and the morphologies and properties of the wood fibers before and after oxidation were characterized by using a fiber quality analyzer (FS300),a dynamic drainage jar (DDJ) and an optical microscope.Then,the oxidized fibers were used to prepare the transparent pa-per,and the effects of the NaClO dosage on the paper properties were discussed.The results show that (1) the in-crease of the NaClO dosage with constant TEMPO and NaBr dosages causes an average fiber length decrease of 0.38mm,an average fiber width increase of 4.7μm,a fine fiber content increase of 8 times and a fiber curl value decrease of 13.9 percentage points as well as a poor pulp drainage property; and (2) as compared with the transparent paper from the wood fibers without the TEMPO treatment,that with the TEMPO treatment achieves a higher tensile strength and a greater elastic modulus with a 5 times tensile index,a 7 times elastic modulus and a 27.0% surface roughness as well as a transparency of 87%.
