Abstract

The Purpose of this study is to investigate dyeing properties of fabrics with rhubarb colorants. Rhubarb colorants were extracted with water from sliced dry root of rhubarb. Using rhubarb extract, wool fabric specimens were dyed under various conditions(temperature, time, pH, mordants). Effects of dyeing conditions and mordanting on dyeing properties and colorfastness were studied. The color of the dyed fabric specimens were predominantly yellow for all of the pH range. The optimum condition for dyeing with rhubarb extract was dyeing at $80^{\circ}C$ for 30minutes. Al of 4 kinds of mordating agents and pre-mordanting showed the highest chroma value. Washfastness was 3-4, but the dyed wool fabrics became darker on light exposure.
