INVERSTIGATION OF RUBIA CORDIFLORIA (INDIAN MADDER) DYE ON SILK FABRIC

Abstract

Synthetic dyes release huge amount of waste and uniform colourants lead to health hazard. It also disturbing the\necobalance of the nature. Natural dyes are mostly derived from plants, invertebrates, or minerals. The most of the natural\ndyes are vegetable dyes from plant sources-roots, berries, bark, leaves, and wood—and other organic sources such as fungi and lichens. Natural\ndyes exhibit good biodegradability and are more compatible with the environment. In spite of their inferior fastness, natural dyes are more\nacceptable to environmentally conscious people around the world. The present study deals with the natural dyes extracted from Rubia Cordifloria.\nThe extracted dye used to dye selected silk fabric and myrobalan mordant used for dye ability, fastness properties, absorbency test. Two shades\nwith different concentration have been developed. Absorbency properties of the dyes extracted from madder and sinking test was determined. The\ncolour fastness through washing and rubbing (Wet and Dry) was an excellent satisfaction in both different concentrations.
