摘要

The purpose of this study was to investigate dyeing properties of silk fabrics using rhubarb colorants and mordanting agent. Rhubarb colorants were extracted with water from sliced dry root of rhubarb according to traditional method. Silk fabrics were mordanted with 3% o. w. f. in mordanting solution at a liquor ration 30:1. And silk fabrics were dyed under various conditions (temperature, time, and pH). Effects of dyeing conditions and mordanting agents on dyeing properties and colorfastness of silk fabrics were evaluated. Wash fastness and light fastness tests were carried out according to KS K 0430 A-1 and AATCC16 1990, respectively. Color difference (△ E) based on L, a, and b was determined using spectrocolorimeter (Hunter Lab UltraScan XE). Relative color strengths (K/S values) were determined using Kubelka-Munk equation. The color of the dyed fabric specimens was predominantly yellow for all of the pH range. The optimum condition for dyeing with rhubarb extract was dyeing at 80℃ for 30 minutes. Al of 4 kinds of mordating agents and pre-mordanting showed the highest chroma value. However, mordanting procedure was not effective for silk fabrics for improving dye uptake.
