225-231Tender coconut husk, a waste after consuming the coconut water, has been explored as a dye for the colouration of cotton
fabric. It is abundant in polyphenolic compounds which are the main coloring agent. The aqueous extraction method is used
for obtaining the dye. Different mordanting techniques, such as pre-mordanting, simultaneous mordanting and post
mordanting, are used to dye cotton fabric. Tannic acid and alum are used as primary mordants, and ferrous sulphate and
copper sulphate are used as secondary mordants. A range of shades is obtained by varying mordants and different
mordanting methods. Overall fastness properties of these shades are found good. Dyed fabrics are also found to have an
excellent UV protection property
