APPLICATION OF NANO POLYMERS AND FUNGICIDES IN CONSERVATION OF A BIODETERIORATED COPTIC TEXTILE OBJECT

nr katalogowy: 70852

This study represents an applied study case in conservation of a biodeteriorated Coptic textile object. In this study the fungal microflora deteriorating the selected textile object was identified. Various investigation methods were used to assess the statement of the textile object before establishing any conservation processes. Then different conservation processes were established and used to conserve the selected Coptic textile object according to the condition and statement of the selected object. The results show that the most dominant fungi isolated from the current textile object belong to Alternaria, Aspergillus, Chaetomium, Penicillium and Trichoderma species. In this study various techniques were used for treatment and protection of textile object against the fungal deterioration. For disinfection of fungal infestation on the Coptic textile object, a fungicide that is safe for both the textile object and the conservator has been used. Various methods were used for cleaning the textile object and for removing the fungal stains from the biodeteriorated textile object. The current textile object was consolidated and reinforced using modified nano polymer (microemulsion polymer prepared from Methyl methacrylate (MMA) and Hydroxy ethyl methacrylate (HEMA) monomers using Eco-friendly initiation system represented as ultrasonic mechanism). The selected nano polymer was applied on a silk screen that has been previously treated with Neo-Desogen fungicide. The treated new silk screen was used for reinforcement of the textile object. Treatment of this textile object by the suggested nano polymer and fungicide not only reinforces this textile, but also prevents fungal deterioration and increases the durability of this textile object. Finally the current study suggested recommendations for display of the current textile object in its showcase in the museum.
