Investigation of a method to test the dimensional instability of restoration papers for ancient books
The selection of restoration papers is an important step in the restoration of ancient books,but their dimensional instability has not attracted enough attention.Restoration papers for ancient books are traditionally hand-made and have low strength after being soaked in water.The use of the current national standard testing method for dimensional instability of papers may cause the ripping and deformation of restoration papers.Therefore,a method to test the dimensional instability of restoration papers,namely the spraying method,was proposed.The relative moisture contents of restoration papers were measured using a moisture detector,in order to verify the feasibility of this spraying method from the perspectives of measurement time and operability.Moreover,the results of the spraying treatment and the soaking treatment achieved good consistency through analysis of the wetting-drying dimensional instability of more than ten kinds of commonly used restoration papers.We also discuss the applicability of dimensional instability testing to ancient books,and suggested the analysis of the dimensional instability matching degree between ancient book paper and restoration papers before restoration according to some specific cases.Since the spraying method effectively avoids the tensile deformation or fracture of restoration papers seen with the soaking method,the spraying method is suitable for the non-destructive testing of both restoration papers and ancient book paper.Thus,this method provides a scientific basis and a reference for the formulation of restoration strategies for ancient books.
