The Detection of Mordants by Energy Dispersive X-Ray Spectrometry: Part I. Dyed Woolen Textile Fibers

Abstract

Twelve mordanted and cochineal dyed modern wool samples were subjected to scanning electron microscopy and energy dispersive X-ray spectrometry (SEM-EDS) analysis. The analyses for metallic elements matched in all cases those actually used in the preparation. The mordants detected contained the metallic elements: aluminum, chromium, copper, iron, and tin. SEM photomicrographs were also examined for the effects of mordanting on fiber surfaces. Atomic absorption (AA) analysis of the samples is also reported.
