Abstract:
In this study, mango (Mangifera indica) leaves were selected as a natural dye and myrobalan was selected as natural mordant and alum as a metallic mordant to use in dyeing and eco-printing of eri silk fabric. The colour of mango (Mangifera indica) leaves dye obtained was deep yellow colour but turned yellowish green and buff yellow when two different mordants namely, alum and myrobalan were added to it. The effect of mordant on dyeing and eco-printing were compared with the mordanted and non-mordanted dyed and eco-printed fabrics. The result revealed that alum mordanted and myrobalan mordanted fabrics showed very fair colourfastness when exposing to sunlight and wet crocking method. While in perspiration and pressing methods, all the sample fabrics showed very fair to fair, good to no stain and neglible to slightly stained respectively.
