发笺纸的现代仪器分析--以《天经或问》为例

Modern Instrumental Analysis on Fajian Paper--Taking Tian Jing Huo Wen as an Example

发笺纸在我国造纸史上占据重要地位,但其造纸工艺在学界一直存在争议。北京大学图书馆在古文献修复过程中发现馆藏和刻本《天经或问》的书衣中间层是发笺纸,黑色细丝分散于纸张表面。本研究利用光学显微镜、纤维测量仪、扫描电子显微镜和傅里叶变换显微红外光谱仪对纸张纤维和黑色细丝进行现代仪器分析。结果表明,该发笺纸的纸张纤维是楮皮纤维,黑色细丝的主要成分是人类头发。该结果可以为发笺纸的历史考证和工艺恢复提供一定的科学依据。

Fajian paper plays an important role in papermaking history of China,but the papermaking process has been controversial in academic circle. The middle layer of the book cover of Tian Jing Huo Wen,which was repaired in Peking University Library,was found to be Fajian paper with black filaments dispersed on the surface. The paper fibers and the black filaments were analyzed by using optical microscope,paper fiber analyser,scanning electron microscope and infrared spectrometer,the results showed that the fiber of the Fajian paper was from paper mulberry,and the main ingredient of the black filament was human hair,which provided a scientific basis for the historical research and process restoration of Fajian paper.
