Environmentally Friendly Multifunctional Treatments of Textiles with Photo-Active Colorants

Abstract:

As an effort to develop environmentally friendly light-induced functional treatments for fabrics, certain acid dyes were incorporated onto different fabrics. The treated fabrics demonstrated powerful and durable antimicrobial and oxidative detoxifying functions after light exposure. In this presentation, we will report the latest progresses in using certain anthraquinone compounds in treatments of wool, nylon, silk and cotton fabrics. The dyed fabrics could demonstrate antimicrobial functions upon exposed to UVA (365 nm) and fluorescent 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 textiles.
