Saffron Petals, a by-product for dyeing of wool fibers ‎

nowadays, natural dyes obtained from bioresources are significantly used in many applications such as textile and carpet industry. As a natural dye, saffron petals are used in this study for dyeing wool fibers. A series of dyeing formulations were prepared with saffron petals and different mordants. The mordant effect on hue, light and wash fastness of dyed fibers was investigated. The results showed that varied hues from light yellow to light brown were obtained. It was found that the best mordants in this study to improve wash and light fastness of dyed fibers were FeSO4 and Na2Cr2O7.
