Implication

The study identifies fabric dyes in textiles using non-invasive techniques, suggesting advancements in conservation methods.

Key Points

  • The aim is to identify natural dyes in historic textiles using non-invasive techniques for better conservation.
  • Utilized FORS (Fiber Optic Reflectance Spectroscopy) to create a spectral database of dye reflectance spectra.
  • Tested a hyperspectral camera (Specim IQ) for non-invasive imaging of dye distribution.
  • Applied Spectral Angle Mapping (SAM) to identify spectral similarities in imaging.
  • Acquired colorimetric data with a spectrocolorimeter to determine chromaticity coordinates.
  • Developed a comprehensive spectral database for twelve natural dyes and their mordants.
  • Successful identification of dye patterns across larger areas using hyperspectral imaging.
  • Effective mapping of spectral features directly onto images using SAM.
