Fig. 3: Application of Dye on Cotton Cloth
The mordanted cotton cloth was immediately used
for dyeing because some mordants are light
sensitive. The chromatophore of the dye makes it
resistant to photochemical attack, but the
auxochrome may alter the fastness (Jothi, 2008).
Good light fastness was observed in fabrics dyed
with the dye extracted from pomegranate peel. This
is due to the formation of complex with the metal
which protects the chromatophore from photolytic
degradation. Wash fastness of the dye is influenced
by the rate of diffusion of the dye and state of the
dye inside the fiber (Jothi, 2008). The fiber dyed with
pomegranate peel dye showed moderate wash
fastness. Good rub fastness was exhibited by the
fibers dyed using the dye extracted from the
pomegranate peel. Complexing the fiber with
mordant, has the effect of insolubilizing the dye,
making it color fast. The fabrics dyed with
pomegranate rind exhibit good fastness propert
