초록
The main colorant of Morus alba L. fruit is anthocyanin which is a kind of flavonoid group. In this article, the dyeing properties of colorant extracted from Morus alba L. fruit were investigated on some silk fabrics. The results were as follows: The maximum absorbance of Morus alba L. fruit showed at 284 nm, and 516 nm by UV-VIS spectrophotometer. The dye adsorption increased according as dye concentration. The optimal dyeing temperature was 60oC and the dye equilibrium was reached 40 minutes after dyeing. The highest K/S value of the colorant obtained at bath ratio 40:1. The effect of pH of dye solution showed higher K/S value at acidic than alkaline condition. Almost Mordants except pre-Fe and Sn did not significantly increased dye adsorption. The pre mordanted silk fabrics showed RP, P, and post mordanted ones showed PB, GY. The color fastnesses to light, washing, and perspiration were modified at pre-Sn mordanted samples
