书画修复用宣纸性能的研究

Studies on Xuan paper for restoration of Chinese painting and calligraphy

宣纸是我国传统书画装裱重要的修复用纸,近年来由于生产工艺的改变造成宣纸性能的改变。为了解不同宣纸书画装裱的适用性,对02红星棉料单宣、08红星棉料单宣、14红星棉料单宣、13汪六吉棉料单宣、红星特净和红星古艺宣六种宣纸的基本性能、尺寸稳定性、柔软度和耐久性等进行评测。分析结果表明:几种常用书画文物修复宣纸pH值符合文物保护用纸中碱性的要求;棉料单宣中以02红星尺寸稳定性、柔软度及耐久性好;采用传统工艺制作的古艺宣纸尺寸稳定性和耐久性能是所选纸样中最好的,柔软性低于棉料单宣,但比同样材料的特净皮单宣柔软度好。综合考虑修复纸的应用性能和耐久性,需要进一步开发采用传统工艺制作的古艺宣的原料种类,以满足书画文物保护修复的需要。

Xuan paper is an important material used for restoration of Chinese painting and calligraphy, but its quality has been affected by changes in the production processes in recent years. In order to understand the applicability of different Xuan papers, six different Xuan papers were tested and evaluated. These six Xuan papers are Hongxing （RedStar） 02, Hongxing 08, Hongxing 14, Wang - liu - ji 13, Hongxing super - pure and Hongxing ancient - style. The evaluation parameters include basic properties, sizing stability, softness and durability. The re- sults showed that all six Xuan papers are slightly alkaline. Hongxing 02 （Xuan paper produced in 2002） performs better than those papers produced later; Hongxing ancient- style （Guyi Xuan paper）, produced by traditional processes, also is of better quality. In order to extend the life span of paintings and meet the needs for conservation, a new kind of Xuan paper produced by traditional processes should be developed.
