A Study on Colorimetric Attributes of Natural Fibers Dyed with Natural Colorants

Today, due to the concerns about the importance of environmental issues, the tendency of applying of natural dyes for dyeing the textile materials has been increased. In this regard, it is preferred to apply the natural additives instead of synthetic materials for pre-, meta- and post treatment processes. As instance, the use of herbal mordant instead of those of mineral or metal for dyeing process of natural fibers has been extremely attracted attentions. However, replacement of metal mordant by the herbal ones will influence both the colorimetric attributes as well as the color fastness of the final product. In this report, the basic concepts and studies related to definition of colorimetric attributes of natural dyes employed for cotton, woolen and silk textiles have been considered, firstly. Then, the effect of applying of natural dyes on different fastness properties, i.e., light fastness, wash fastness, wet and dry rubbing fastness have been reviewed.
