Abstract

Abstract The crystallinity indices (CrI) of Chinese handmade papers were investigated using the X-ray diffraction (XRD) method. Four Chinese handmade papers, Yingchun, Zhuma, Yuanshu and Longxucao papers were used as model substrates of mulberry bark, ramie, bamboo and Eulaliopsis binata papers, respectively. Two forms of the paper samples, paper sheets and their comminuted powders, were used in this study. The results showed that their XRD patterns belong to the cellulose-I type and Iβ dominates the cellulose microstructure of these paper samples. Moreover, it was found that the microstructures and CrIs of cellulose of these papers were changed by the grinding treatment. This work suggested that the sheet form of the handmade papers is suitable to determine CrI by XRD, despite the contribution of non-cellulosic components in the papers. The order of CrIs for these paper sheet samples was Yingchun, Zhuma, Longxucao and Yuanshu papers. Besides CrIs, differences in cross-sectional areas of the crystalline zone of cellulose can be used for comparing different types of handmade papers. It was also found that the CrIs and crystallite size of paper cellulose varied between the sheet samples and the powder samples, illustrating that the pulverisation has a negative influence on the microstructure of the handmade papers.

X射线衍射法测定中国手工纸的结晶度

摘要采用X射线衍射（XRD）方法研究了中国手工纸的结晶度指数（CrI）。以迎春纸、竹马纸、圆树纸和龙须草纸四种中国手工纸分别作为桑皮纸、苎麻纸、竹纸和龙须草纸的模型基质。在本研究中使用了两种形式的纸张样品，纸张和它们的粉碎粉末。结果表明，它们的XRD图谱属于纤维素-I型，Iβ主导了这些纸样品的纤维素微观结构。此外，还发现这些纸的纤维素的微观结构和CrIs在研磨处理后发生了变化。这项工作表明，尽管纸中存在非纤维素成分，但手工纸的片状形式适合通过XRD测定CrI。这些纸张样本的CrIs顺序为迎春、竹马、龙须草和袁书。除了CrIs之外，纤维素结晶区横截面积的差异也可用于比较不同类型的手工纸。还发现，纸纤维素的CrIs和微晶尺寸在片状样品和粉末样品之间变化，表明粉碎对手工纸的微观结构有负面影响。
