Innovations resulting from technological advancements represent the best strategy for success inthe increasingly competitive textile industry. Recently, fragrances have become available thatcan be readily formulated into polymer fibers. Properly designed textiles containing effective,long-lasting fragrances would provide a significant contribution to the textile industry. Theproposed research will investigate new fragrance technologies for use in new and boutiquetextile technologies. The team will explore the incorporation of scents into polymer fibers, theproduction of scented fabrics with and without corresponding pigments to modify the response,and the psychology of acceptance of synthetic scents in textile goods. As progress toward thisgoal, we have identified a supplier for scented-infused fabrics, researched potential odors thatcan be introduced into textiles, and researched market possibilities for scented textiles
