Forensic Discrimination of Dyed Textile Fibers using UV-VIS and Fluorescence Microspectrophotometry

Abstract

Ultraviolet-visible (UV-VIS) and fluorescence microspectrophotometry (MSP) offer direct, relatively inexpensive, and informative means of characterizing dyed textile fibers. Visual comparisons among the fiber spectra have been supplemented by multivariate statistical analysis to confirm the statistical validity of discrimination observed. Overall, UV-VIS and fluorescence microspectrophotometry are valuable tools for the discrimination of fibers, in particular for discrimination of fibers of similar color but different dye composition.
