摘要: Resonance Raman and UV-visible diffuse reflectance spectra were recorded from samples of cotton, viscose, polyester, nylon, acrylic textile swatches dyed black with one seven single dyes, a mixture two or mixtures three dyes. The generally gave characteristic the demonstrating that technique is applicable for forensic analysis textiles. Survey studies widely used dye Reactive Black 5 show essentially same spectrum obtained on bulk sampling in solution, cotton at different uptakes, microscope threads fibres. effects laser irradiation bands emission backgrounds without are also reported.
