A microscopical scheme for the examination, identification, and comparison of the synthetic fibers present in dust is proposed. The method involves mounting a sample of dust in a medium with a refractive index of 1.525 at 25°C. and collecting morphological and optical data about the synthetic fibers present in the dust specimen. The data are then used to identify each fiber's generic class and to compare fiber samples. This scheme was designed for examiners with little experience in synthetic fiber examination.
