摘　　要：对桉木浆进行了碱性脱墨、中性脱墨和酶法脱墨,采用扫描电镜(SEM)、X射线衍射(XRD)及红外光谱(FT-IR)等表征手段研究了不同脱墨方式对纤维形态及超分子结构的作用,并讨论了纤维微观结构的变化与纤维润胀性能的关系。结果表明,脱墨方式对纤维形态及超分子结构都有明显的影响,其中碱性脱墨对纤维形态及超分子结构的作用最为明显,中性脱墨次之,酶法脱墨最小。同时,经脱墨处理后,桉木浆纤维保水值总体呈上升趋势,其中碱性脱墨后保水值增加最大。Three kinds of deinking processes, alkaline deinking process, neutral deinking process and enzymatic deinking process, were used for eucalyptus pulp deinking. The fiber morphology and cellulose supramolecular structure were studied by SEM, XRD and FT-IR. The effects of cellulose supramolecular structure on swelling ability were also studied. The results show that the effects of different deinking process on fiber morphology and cellulose supramolecular structure are obvious. Influence of alkaline deinking on fiber morphology and cellulose supramolecular structure is the most significant than others. After deinking processes, the water retention value （WRV） increases, in an order of alkali deinking 〉 neutral deinking 〉 enzymatic deinking.
