Abstract
ABSTRACT Rice straw is a rich source of biomolecules which can be utilized in functionalization of textile fibers. In the present work, rice straw extract was utilized in functional coloration of wool fabric. The dyed wool samples were characterized by EDX, SEM, TGA and FTIR spectroscopy. The dyed wool fabrics were assessed for color parameters, fastness, antibacterial activity, UV protection, and flame retardant properties. The results showed that dyeing with rice straw extract in the presence of inorganic metal salts produces different elegant hues with acceptable fastness properties. Wool samples dyed with mordant ions also demonstrated potent antibacterial activity against S. aureus, high UV protection, and flame retardant effects. Our results clearly pointed out that rice straw extract could be used as an inexpensive yet effective textile dye and would be a feasible alternative for some synthetic agents in the development of protective clothing for various end uses.
