The Development of a Spectral Data Base for the Identification of Fibers by Infrared Microscopy

摘要: A detailed study of the application infrared (IR) microscopy for single fiber analysis has been initiated. Spectra synthetic fibers were obtained rapidly and reproducibly with minimal sample preparation. Minor spectral variations, caused by deformation during preparation, observed between samples. These variations never sufficient to prevent identification polymeric materials. An IR library 43 polymer fibers, which distinguishable their spectra, was constructed. The chemical subclass unknown exception acetates nylons, could be accurately identified a computer search using an absolute derivative difference searching algorithm.
