[Research on the silk aging with x-ray diffraction spectra].

The present paper did some researches on the deterioration mechanism and the changes in crystallinity of silk fabrics by means of the X-ray diffraction analysis. The samples artificially aged and excavated from Hubei, Innermongolia, Shaanxi and Qinghai provinces were analyzed. The artificial aging was done by simulating three main natural aging factors: light, heat and hydrolysis. The analytical results show that X-ray diffraction analysis could reveal the aging process and characteristic of silk, as well as the changes in crystallinity during silk aging. The X-ray diffraction analysis is of practical value for the conservation state and aging mechanism studies of ancient silk. In addition, X-ray diffraction analysis could also provide important information on ancient technology of textile and apparel.
