The effects of finishing silk fabrics with the multifunctional epoxide EPTA
have been studied. The content of basic amino acids and tyrosine in silk f
ibroin decreased remarkably. Wetting properties of the EPTA-finished silk f
abrics such as water-fabric contact angle and water retention capacity chan
ged slightly, while dyeing behaviours showed a marked difference. The rate
of hydrolysis of the EPTA-finished fibroin in alkaline solutions was slower
than that of the unfinished control samples.
