Cultural level damage is mostly the result of chemical damage and physical injury at the same times, they will make the appearance, feel,
color, molecular weight and the degree of crystallinity changed. Some scholars pointed out that the aging of silk is the result of many factors. Only the aging mechanism of a single environment is effectively understood, further investigate of the aging process can be realized under various factors.
At present, artificial aging method is widely used, in order to simulate the ancient silk preservation and storage conditions. Mainly thermal aging, light aging, hydrolysis aging methods and soilembedded and so on.
