中文摘要 | 在紙質文物劣化現象中,褐斑(foxing)不但影響視覺美觀,同時也降低其存世年限。本文彙整相關研究報告,冀能對褐斑有進一步的認識。 紙質文物常見的褐斑型態有三種:1.雪花狀褐斑 2.靶心狀或靶狀褐斑 3.複合型褐斑-上述褐斑同時呈現於紙上者。 褐斑發生的原因可能是:1.生物性因子:紙質文物上散布著黴菌孢子,在適合黴菌生長的溫濕度等條件下,其代謝產生的胺基酸和有機酸,與紙質纖維素被黴菌分解生成的醣類,進行Malliard反應,生成褐色的物質(melanoidine)。2.非生物性因子:造紙原料或製造、加工過程中殘留在紙上的金屬離子(以鐵離子為主),導致紙張褐色斑點的生成。3.其他因素:結合上述生物性及非生物性因子,或環境等較複雜的因素。 由褐斑發生的可能原因看來,只要符合褐斑生成條件,褐斑也可能在其他材質,如絲質或壁畫等文物上發現。 |
英文摘要 | Foxing is one of the deterioration phenomena of paper. It not only affects the esthetics, but also the shelf life. In this paper, we review the related research and hope the we can have more knowledge about Foxing. There are three types of Foxing found in paper. 1. Snowflake foxed spots 2. Bullseye or target shaped foxed spots 3. combined form-both of the above mentioned spots existing in the same paper. The possible reasons for foxing forming are 1. Biological factor: Mold spored spread in paper randomly. They will grow in the proper environmental conditions. The metabolites of mold, amino acids and organic acids react with the digested products from cellulose, glucose or oligosaccharide, and form brown melanoidine spots by Malliard reaction. 2. Nonbiological factor: The materials of paper or the metallicion contaminated from paper producing or processing procedures, especially ironion, form foxing. 3. Other factors: combined the above two factors or other complicated environmental factors. From the forming hypothesis, foxing can be found in other materials, for example silk or wall paintings; if condition is allowed. |
