Assessment of fastness properties of knitted cotton fabric dyed with natural dyes: a sustainable approach of textile coloration

Abstract

Now-a-days, the importance of natural sources is eminent because the increased awareness created due to most of the adverse effects of synthetic products. In recent years, it has been significantly important to use non-toxic & eco-friendly natural dyes to dye textile materials. Though a lot of research work was done on the application of natural dyes on textile materials, natural dyes was not been proved satisfactory. There is a main reason behind this which is the absence of a broad systematic study of the performance of these natural dyes. Extraction of natural dyes for the coloration of textile substrate is one of the most important research areas for the researchers. In this study, we tried to extract the natural dyes from Arjuna bark, myrobalan fruits, Bohera fruits and amla fruits. After extraction, cotton knitted fabric sample was dyed with extracted dyes by using mordant and without mordant. And then their colorfastness properties were evaluated.
