Silk fabrics Dyed with Archidendron jiringa pod - the Application of Color and UV Protective Properties

Abstract

Archidendron jiringa pod (AJP) has been extracted. Its dye ability of silk fabric has been studied together with its colorfastness and UV protection properties. The mordants such as aluminum potassium sulfate, ferrous chloride and sodium hydroxide were used to dye fabric. The color fastness to washing, water, perspiration, light and crocking of the dyed samples was determined according to AATCC test methods. In this study the UV protection properties were investigated on silk fabrics. The chemical functional groups of the dyes were characterized by using Fourier transform infrared spectroscopy (FTIR). Silk fabrics mordanted with ferrous chloride and dyed with AJP usually showed good UV protection levels even if undyed. These extracts yielded polyphenols, betalain dye, chlorophyll, carboxylic and djenkol acid contents. Therefore, it was suggested that AJP has the potential in producing functional dyes that could be imparted into the silk dyeing natural colourant system.
