Trace textile fiber evidence is found at numerous crime scenes and plays an important role in linking a suspect to the respective scene. In this work, investigations into the fluorescence of the fiber dyes, and the fibers themselves, as well as a methodology for discriminating between fibers using room temperature fluorescence (RTF) are reported. Initial systematic analysis was conducted on dye standards and extracts taken from fibers colored with the respective dyes of interest.
