摘要

In this study, the silk fabrics mordanted at the rates of 1%, 2%, 3%, 4%, 6%, 9%, 12%, 14%, 18%, 21%, 24%, 27%, 30%, 33% and 36% of alum (KAl(SO4)(2).12H(2)O) were separately dyed with chrysin, quercetin dihydrate, 7,8-dihydroxyflavone and naringenin flavonoids. The CIEL*a*b* color values of the performed dyeings were measured and compared with each other. According to the results of the color measurement, the dyeings obtained using the mordant of 6% alum showed the best color values. The bonds relating to the amino acids present in Bombyx mori silk were characterized by FTIR. Also, the binding to the fibroin protein via Al-O and Al-N bonds of Al (coming from alum mordant) was determined. The amino acids including of pure silk were specified by C-13 CP/MAS NMR. The coordination numbers of Al (III) ions in the complexes formed among the silk fibroin-mordant-dye were determined by Al-27 MAS NMR.
