Dyes as Photo-Active Functional Agents on Protein Fibers
As an effort to develop environmentally friendly light-induced functional treatments for fabrics, certain acid dyes were found having photo-active functions. In this presentation, we will report the latest progresses in using certain anthraquinone dyes in acid dyeing of wool fabrics. The dyed fabrics could demonstrate antimicrobial functions upon exposed to ultraviolet-visible light. However, it was more interesting to observe that the surfaces of the dyed wool fibers became polished with scales removed after being exposed to UV or day light for certain time. The chemical structures and thermal properties of the dyed fabrics were investigated by using different instrumentation such as SEM, FTIR, and other instruments, and the results verified the proposed oxidation reactions of the fibers. This research proves that dyeing fabrics with photo-active dyes could be a new green functional treatment on wool fabrics.
