Abstract:
The Rubia cordifolia L. species, sometimes referred to as Majith and Indian Madder, is one of the most prominent and useful species of the genus Rubia on the Indian subcontinent. Rubia cordifolia was selected as natural dye for the study. Eri Silk fabrics and Natural mordant myrobalan and Metallic mordant alum was selected for the study. The non-mordanted fabric gave the greater depth of colour and myrobalan mordanted fabric had highest 16.26K/S value. According to the FTIR spectra, all of the dyed samples showed different peaks from the raw fabric. It was also noted that the peaks of the dyed samples varied somewhat because of various mordants. Compared to alum-mordanted fabric, myrobalan- mordanted fabric has a smooth, uniform surface.
