Synthesis of Fragranced Dyes and Their application to Cotton Textiles

D.P. Chattopadhyay, Shweta J. Doctor


The aim of the study was to synthesize fragranced dyes and application of these dyes to cotton fabric. β-cyclodextrin was grafted to heterobifunctional reactive dyes and the cavity of the cyclodextrine was utilized for loading various fragrances in it. The modified dyes were characterized by FTIR and UV/VIS spectroscopy. The fragranced dyes were used for dyeing of cotton fabrics. The treated samples were subjected to number of washing cycles as well as exposure to sunlight for prolonged time to study the fragrance retention on the fabric. The extent of attachment of the modified dye and colour strength developed on cotton fabric were determined. Olfactometrical analysis of the dyed fabric was conducted to have an idea of perfume retention onto the fabric.
