Abstract:

In this paper, synchrotron based infrared micro-spectroscopy was utilized to describe the degradation profile of fibroin contained in silk textiles (Bombyx mori). The spatial distributions of deterioration effects in silk samples artificially aged at an assortment of conditions (thermal, hydrolytic and ultraviolet) were distinctly visualised and in accordance with the findings from conventional infrared spectroscopy in references. Further this method was applied on a historic sample from a private collection in Melbourne, and presented consistent results. This established synchrotron IR chemical mapping method could enable museum professionals to better understand the preservation state of historic silk and make informed decisions for conservation.
