Abstract
A woollen fabric sample has been oxidized by electro-generated oxygen species produced at a platinum electrode. This treatment produced three visually discoloured or bleached regions. The areas of the fabric that were located close to the electrode surface showed dark brown discoloration. On either side of this region, bleaching of the wool was apparent to various degrees. Fabric well removed from the electrode appeared unaffected by the treatment, and was used as a reference. Such samples were analysed by the complementary techniques of FT-IR and FT-Raman spectroscopy, and the pattern recognition method of principal components analysis (PCA). The samples were successfully separated into three groups on the basis of the levels of known oxidation intermediates from cystine and other readily oxidizable amino-acid residues present in wool-keratin.
