| 초록 |
Silk fabrics mordanted with Fe2+, Ni2+, and Cu2+ were dyed with the aqueous extract of Cassia tora
L. seed which was known to include water soluble colorant kaempferol, one of flavonol compounds. Kaempferol
can react with free radicals and chelate transition metal ions, which is thought to catalyze processes leading to
the appearance of free radicals and have antioxidant activity. In relation to the coordinating and chelating
mechanism of the ions with the silk protein and kaempferol, reasonable conclusions should be made on the
colorant uptake and the water fastness of the fabric. The amount of the colorant on the fabric was in the order
of Fe2+>Ni2+>Cu2+. In case of dyeing through coordinaiton bonds between transition metal ions and silk protein
and colorants, it was thought that the ions with the smaller secondary hydration shell, the higher preference to
the atoms of the ligand coordinated, and the suitable bonding stability for the substitution of primarily hydrated
water molecules for colorants led to the higher colorant uptake.
The water fastnsess of the fabric was in the order of Fe2+>Cu2+>Ni2+. It should be reasonable to choose transition
metal ions with weak and strong tendency to the ionic and the coordination bond, respectively, to the carboxylate
anion of the silk protein.
Although further research needs to be done, the conclusions above may be generally applied to the natural dyeing
through the coordination bond mechanism between transition metal ions and colorants and substrates. |
