Assessment of Dyeing Properties of Natural Dye Extracted from the Fruit of Myrobalan (Phan-Kha)

Abstract

In this study, natural colorant extracted from the fruit of Myrobalan (Phan-kha) was applied on cotton fabric using alum, copper sulphate and potassium dichromate as mordant. The effects of mordant, dyeing time and dyeing temperature on the color strength of dyed cotton fabrics were measured. The fastness properties of dyed cotton fabrics such as washing fastness, rubbing fastness and light fastness were also evaluated. It was found that using the metal mordants increased the color strength of the dyed cotton fabrics. It was shown that all mordants increased in rubbing fastness and washing fastness of dyed cotton fabrics, but the light fastness increased in the used of copper sulphate and potassium dichromate mordants
