Study on the Aging Degree of Historical Silk by the Surface Resistance Method.

The existing historical silk, which has great historical and academic research value, is an indispensable and important carrier for the study of global ancient civilization. It is very important to scientifically evaluate the preservation status of such silk. In this paper, the corresponding relationship between the surface resistance and the retention rate of breaking strength was established by testing simulated samples of photoaged silk fabrics. The effectiveness of the surface resistance method was suggested by amino acid analysis and infrared spectroscopic analysis. The test results show that the surface resistance method is a simple and fast nondestructive test to establish improved rules of consideration for the aging degree of silk relics. According to the corresponding relationship between the surface resistance and the retention rate of breaking strength, the current breaking strength of the fibers of historical silk can be inferred, which provides a scientific basis for the aging evaluation and protection of historical silk.
