Study on the Extraction of Colorant from Areca Nut and Employing it in Dyeing Silk Fabric

Abstract

The effect of parameters on the extraction process of colorant from areca nut and the application of extracted colorant in dyeing silk fabrics has been studied. The optimum dye extraction conditions are obtained: 10 grams of areca nut / 100 mL of water, pH = 10, extraction temperature 90°C, extraction time 120 minutes. Areca nut extract is a natural dye for dyeing silk fabrics under conditions of 90 minutes dyeing time, 80°C dyeing temperature. In this study, aluminium sulphate was used as a mordant. The dyeing properties were evaluated by CIELAB. The areca nut dyes provide a reddish brown shade on the fabric. The color fastness to washing, perspiration and rubbing of the dyed fabric was in good level. The dyed silk fabric has no formaldehyde and azo-amine compounds.
