Abstract

UV-absorbers were first used in sunscreens to protect human skin against harmful UV-rays by 1928. Since then, with awareness of different benefits of UV-absorbers, their usage was progressively increased and numerous researches have been performed to find out and extend their applications. In textile and hand-woven carpet industries, high energy UV-rays are very harmful for both fibers and dyed substrates since its energy degrades polymeric chains of fibers as well as dye structure and causes fiber properties loss, color fading, etc. Hence, numerous studies have explored the potential of UV-absorbers in light fatness enhancement of colored substrates and UV-protection of fibers. In this paper, UV-absorbers used for finishing of textiles are reviewed particularly with focus on the natural based products, i.e., natural fiber, natural dye, natural UV-absorber, etc. Overall, promising future is expected for identification and introduction of novel UV-absorber materials with desired performance.
