【 摘 要 】

A consolidated method by EGDE (ethylene glycol diglycidyl ether) and Ala (alanine) was used for fragile ancient silk fabrics protection. Therefore, an investigation has been carried out to figure out the effect of consolidation material in the system. Silk fibers were dyed with madder and then exposed to UV light beams for accelerated aging. The aged madder-dyed samples were treated with EGDE aqueous solution by spraying, and then treated with Ala aqueous solution by the same way on 10 minutes later. The samples were investigated by colour measurement and scanning electron microscopy (SEM). It has been observed that there is an obvious change of colour of samples after consolidation material treatment. The surface of the aged madder-dyed silk fabric were covered with EGDE and Ala thus protecting the silk fibers.
