摘要
纸张在浸湿和干燥过程中的伸缩性是影响古籍修复用纸使用性能的重要指标。为了改善新制修复用纸的伸缩率,实验采用湿热加速老化法处理6种修复用纸样品,测定和分析老化过程对纸样伸缩性的影响。结果表明湿热老化可以显著降低纸样的伸缩性,尤其是能明显降低修复用纸的横向伸缩率和干缩率,短时间的湿热老化就能将新制修复用纸的伸缩率降至接近老纸的水平。
The stretch of paper in the process of soaking and drying is an important index that affects the performance of paper used for ancient book restoration.In order to reduce the stretch rate of newly-made restoration paper,six kinds of restoration paper samples were treated with the hygrothermally-accelerated aging method,and the influence of the aging process on paper stretch was determined and analyzed.The results show that the hygrothermal aging can significantly reduce the stretch of paper,especially the lateral expansion rate and dry shrinkage rate.A short period of hygrothermal aging can reduce the stretch rate of newly-made restoration paper to a level close to that of old paper.
