Abstract:In this study, wool textiles were examined by optical and scanning electron microscopy to get supplemental morphology data to add to the archaeology research database. Then the samples from tombs in different geological layers were classified based on infrared testing results. The state of conservation of the samples and the influence of burial location on the samples were discussed. The results show that burial location has a great influence on the state of conservation of the samples. The major characteristics of wool deterioration are:cracks in the fiber (traverse section or longitudinal), the change in ratio of the amideⅡand amide I absorption peaks, and crystals formed on fibersdue to rain and groundwater.
