红茶菌发酵液清洗丝织文物表面结晶盐的应用研究

在我国考古出土的丝织品数量多,种类丰富,但由于墓葬环境的特殊性,如棺液的浸泡等原因,丝织文物的表面形成很多结块,影响了文物的品质。因此,对此类丝织文物的清洗成为文物保护工作的重要一环。为此,本研究以唐代出土丝织文物残片表面的结块为研究对象,利用拉曼光谱和X射线衍射仪检测技术对其表面结块的成分进行分析。结果表明,结晶盐的主要成分为CaSO4.2H2O。本研究针对其结晶盐的成分,再利用显微观察、抗拉强度检测等手段分析了红茶菌发酵液对老化的现代蚕丝影响。在得出没有损伤的基础上,利用红茶菌发酵液中的生物有机酸和生物酶作为生物清洗剂清洗唐代丝织文物残片表面的结晶盐,取得了良好的清洗效果,对丝织文物本身无损伤。

Application of Kombucha fermentation in washing crystal fouling on silk cultural heritage

In China,silk relics have been excavated in large quantity and variety;however,because of the relative high humidity of the burial environment,some silk relics were even soaked in the liquid in coffin,and a lot of crystals formed on their surfaces,affecting their quality.Therefore,the cleaning of such silk is an important part of heritage conservation.In this study,crystal fouling on the surface of silk relics from the Tang Dynasty was analyzed using Raman spectroscopy and X-ray diffraction.The results show...
