| Abstract | ||||
| The Ancient Egyptian Textiles in uncontrolled museum conditions are exposed to many challenges such as oscillate relative humidity (RH), changing temperature. This paper aim to study the effect of thermal aging procedures on dyed linen with natural dyes such as Madder dye, Turmeric dye mordanted with different mordents such as Alum, Iron III chloride FeCl3 and Copper sulfate CuSO4.5H2O. The main goal in thermally accelerated ageing is to increase the rate of degradation by making use of the fact that the reaction rate is increased with increasing. The dyed linen fabrics after and before ageing were investigated for their mechanical, chemical, and optical properties such as surface morphology, color parameters (CIELab). Interesting results were obtained. These results will help in establishing standard conditions of light and temperature at which the archeological textile objects can be maintained to minimize deterioration. | ||||
