Since laundering textiles can provide a unique fluorescent spectral signature of the whitening agent in the detergent that adsorbs to the fiber, this project investigated the use of fluorescence microscopy to draw from laundered textiles the spectral characteristics of seven detergents adsorbed to single fibers, and principal component analysis of clusters was used to characterize the type of detergent on the fiber.
Abstract
The study found that on dyed nylon fibers, spectra from eight different detergent pairs could be resolved and washed validation fibers correctly classified. On dyed acrylic fibers, five different detergent pairs could be resolved and identified. The study concluded that identification of the detergent type may prove useful in matching a trace fiber to its bulk specimen of origin. 24 references (Publisher abstract modified)
