N2 - To extract red mordant dyes from wool fiber samples, a new method was devised using a solution of 0.1% ethylene diamine tetraacetic acid in water combined with N, N-dimethyl formamide. This method, which was tested on madder, Relbunium, and cochineal dyestuffs having an alum mordant, enabled the authors to analyze the extracted dyes with spectrophotometry for their characteristic absorption curves and also left the fibers sufficiently intact for use in further examinations. The new method is compared with previous dye extraction methods. A case study of its application on samples of pre-Columbian cameloid fibers is presented.
