Historical curtains that are still being used are subject to many damage conditions. Where it affected by the fluctuation in temperature and humidity. In addition, the effect of light, air pollution, misuse as damage factors. The historical curtain in the royal chamber of the Cairo University contains many damage aspects such as stain, dirt, separate parts, missing parts, change in color, and general weakness. A close examination was conducted to determine the type of curtain materials, and the damage aspects. The scientific documentation of the historical curtain was carried out before conservation process .In the begging, the strengthening of the weak and separate parts was carried out prior to the washing operations. Test of color degree stability was conducted for washing solutions. Mechanical cleaning, wet cleaning, sterilization, drying of the historical curtain were carried out using scientific methods. Final installation using silk thread and needle, and by reinforced by polymer adhesion. Restoration operations were recorded by photography.

“…Other types of non-destructive methods, including scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDX) and energy dispersive spectroscopy (EDS), X-ray fluorescence spectroscopy (XRF), and Particle-induced X-ray spectroscopy (PIXE), are employed to examine not only the surface morphology and elemental composition of inorganic samples but also to identify the types and extent of corrosion products present on the surface [ 37 , 38 , 39 , 40 ]. SEM-EDS is an especially productive method for investigating metal threads from different periods and cultures.…”

The subjects of this research are the burial clothes of Polish King Sigismund III Vasa and his wife Constance, which were woven and embroidered with silk and metal threads. Fragments of the textiles underwent spectroscopic, spectrometric, and thermogravimetric analyses. The hydrofluoric acid extraction method was improved to isolate various classes of dyes from the textile samples that had direct contact with human remains. High-performance liquid chromatography, coupled with diode array and tandem mass spectrometry detectors with electrospray ionization (HPLC-DAD-ESI-MS/MS) facilitated the detection and identification of colorants present in the textiles. Cochineal, indigo-, madder-, orchil-, and tannin-producing plants were identified as the sources of dyes used. Scanning electron microscopy with an energy-dispersive X-ray detector (SEM-EDS) was employed to identify and characterize the silk fibers and mordants and the metal threads. The presence of iron, aluminum, sodium, and calcium in the silk threads suggests their potential use as mordants. The analysis of the metal threads revealed that most of them were made from flattened gilded silver wire, with only a few being cut from a sheet of metal. Typical degradation mechanisms of metal threads were shown, resulting from both burial environment and earlier manufacturing process, and the use of the textiles in clothing, i.e., a significant loss of the gold layer was observed in most of silver gilt threads, caused by abrasion and delamination. The results of the thermal analysis confirmed the presence of silk and silver threads in the examined textiles.

“…The most prominent authors who have dealt with the history of origin, but also with the analysis of metal threads in the world and published many papers are Márta Járó [ 12 , 13 , 14 ] from Hungary and Anna Karatzani [ 15 ] from Greece. The composition of metal threads from textiles is most often determined according to the data in the world literature by non-destructive methods Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDX), X-ray Fluorescence Spectroscopy (XRF), and Particle Induced X-ray Spectroscopy (PIXE) [ 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. In our previous research [ 23 ] XRF, PIXE, and SEM-EDX were used.…”

Metal Content and Structure of Textiles in Textile Metal Threads in Croatia from 17th to 20th Century

Textile metal threads were used to decorate historical Croatian textiles. There are three basic types of metal threads usually used on historical textiles in Croatia. These are narrow stripes, wires, and combined metal textile yarn called “srma”, made of metal thread spirally wrapped around the nonmetal textile yarn. Textile yarns were made of silk, linen, wool, or cotton. Metal threads were primarily made of gold, silver, and copper, and different alloys of these metals or threads are layered in the structure. Analysis of metal threads with three different methods was made and the most adequate method for the analysis of metal threads from historical textiles was established. Metal thread analysis was performed with scanning electron microscopy with an energy-dispersive X-ray detector (SEM-EDX), which was determined to be the most suitable for the analysis of historical textiles if cross-section analysis of metal threads is also performed. Textile threads from combined metal textile threads were analysed with a light microscope. This information of the metal threads’ content and structure as well as the composition of textile thread can lead to an understanding of the technology of production threads and also temporal and spatial dating of textile objects which is helpful to conservators and restorers of valuable historical textiles.
