摘要：The aim of this work is the identification of the fiber type, degree of deterioration and of the natural dyes employed in the manufacture of some pieces of Egyptian Coptic textiles in order to help in its documentation and conservation. So, fibers from that Coptic fabric were analyzed using optical microscope and scanning electron microscope with energy –dispersive spectroscopy (EDS) to investigate the surface morphology of the object. X-ray diffraction (XRD) technique was used to define the damage degree of the artifact fibers. The results shows that the deterioration of the fibers is due to ageing. The investigation was completed by the vibrational characterization of indigo natural dye, which was detected by Fourier Transform Infra Red (FTIR) spectroscopy. The archeological fibers were identified as wool dyed with a natural dye (indigo) as the field literature suggests, with samples of this period. The archeological dye has the same characteristic bands as the modern indigo dye. Many metallic substances were detected which suggest the mordanting or the soil effect, accumulated on the ancient artifact. Characterizing the components of the ancient dyes and of the used fabric, could lead to an understanding of the reactions that deteriorate the ancient artifacts, which in turns helps the scientists, art historians and conservators to establish a more detailed data record, to evaluate the present condition of the object so they can restore the artifact properly.
