Dyeing of wool and silk with <i>Punica granatum</i>

Abstract

The application of dye obtained from <i>Punica granatum</i> fruit rind on wool and silk fabric in the presence and absence of environment-friendly mordanting agents has been studied. The dyeing of silk and wool with pomegranate solution is found to be effectively accomplished at <i>p</i>H 4.0. Pre- and post-mordanting employing ferrous sulphate and aluminium sulphate

improve the colour uptake, light fastness and colour retention on repeated washing. The use of such mordants, however, does not improve wash fastness property of dyed substrates.
