Abstract
heritages of an excavated silk fabrics should be preserved without damage. In order to artificially restore the excavated silk fabrics, alkaline aqueous solution, as a simulated corpse, and two kinds of silk fabrics were used. Two kinds of silk fabrics were treated by aqueous alkaline solution according to strength retention value(100, 80, 60, 40, 20%). The fine structure and physical properties of alkaline treated silk fabrics were investigated with various techniques such as wide-angle X-ray diffraction, tensile test, weight loss, shrinkage, SEM, and yellowness. As the alkaline treatment time increased tensile strength of silk fabrics decreased. However, weight loss and shrinkage slightly increased. The diffraction intensity of β-form crystal declined and α-form crystal diffraction intensity disappeared with the treatment.
