Natural dyes are non-allergic, non-toxic, non-carcinogenic and eco-friendly but their use has been limited since the discovery of synthetic dyes in 1856. These synthetic dyes were gaining importance due to low in cost, giving a variety of shades and being available in abundance. However, excessive use of synthetic dyes can create serious health and environmental problems. To solve these issues, many researchers are being focused on the use of natural dyes in textiles. The purpose of this review is to study the colour fastness of the natural dyes including light, wash and rub fastness, the role and use of mordants in the fixation of natural dyes. The role of different types of fibers and blends in natural dyeing fastness property and role of dyeing methods in the colour fastness of natural dyes. This critical review thus would encourage commercial dyers to focus on the use of natural dyes to overcome the challenges associated with the colour fastness property of the natural dyes and determine a significant direction for aspirational goals of future researchers.
