This paper present the strategies for identification the raw material and dyes used in old textile and deterioration and degradation statement of archaeological dyed samples by using physical techniques such as light microscopy, scanning electron microscope and X-ray diffraction. Samples were taken from morocco kilim which was suffering from several types of damage, as a result of natural ageing appearing in brittle fibres, fading in dyes in many parts of it and missing in a lot of parts in many places. Light microscope and SEM were used to identify the kind of fibres, their condition and surface morphology. XRD was used to identify mordant, impurities and dust. Various dyed samples were taken from different eight sites selected from the worst places in statement of damage in the kilim, and examined by optical microscope, XRD and Scanning electron microscope. Main results revealed that the raw material was wool with its significant morphology appearance. XRD analysis revealed that iron sulphate, Alum, copper sulphate, tin was the main mordant existed in. On one hand, these mordants were considered the most common mordants used in archaeological textiles, on the other hand it should be one of the deterioration and degradation factors for old samples. SEM showed the weakness, brittleness and friction existed in dyed wool samples, the reasons of deterioration/degradation was discussed. Finally, the previous analysis provided a suitable plan for treatment the archaeological dyed textile, as it could be helpful for conservator to have a good decision of the procedure and material should be used in the conservation process based on the previously obtained data analysis.
