This study was planned in search of greener alternative to
satisfy the consumers’ growing demand of eco-friendly
products, and progress has been made with this study in
the use of mango leaves extracts. The maximum relative
color strength of the extracted dye liquor was found to be
at pH 10. But the extracted dye liquors have shown good
pH stability in acidic conditions. It was shown that different
fashion hues were obtained on silk fabric from the same
dye extract using mordants and their combinations. Again,
color yields were found to be influenced by the addition of
mordants. In single mordanting, the order of color yield
was ferrous sulfate > alum > tin. In combined mordanting,
the order was ferrous sulfate-alum > alum-tin-tannic acid >
ferrous sulfate-alum-tin > alum-tin. Other color values were
also found to be influenced due to mordanting. Washing
and light fastness properties were found to be from good to
excellent in most of the cases. Thus, on the basis of the
results, it can be said that mango leaves have good scope
for application on silk fabrics.
