| Research Abstract |
In order to examine the degradation of excavated silk cultural properties, study was performed comparing with modern reference silk using mid-infrared and near infrared spectroscopy. As a result of the analysis of excavated silk cultural properties, it was found that amide peak was preferentially changed, and degraded products peak was strongly appeared according to the progress of the degradation. On the basis of these results, the mapping analysis for amide groups of sample fibers having a woven structure was performed. The results clarified that there is a particular area where a distinct change appears. This is a useful index of the degradation for silk cultural properties.
