原始语种摘要: Abstract(#br)In order to understand the pathways leading to the degradation of wool in historical and archaeological textiles dyed with iron tannin dyestuffs, a new approach entailing the determination of the wool lipid component by gas chromatography/mass spectrometry (GC/MS) was used. A wide number of reference specimens prepared with five different plant tannin, also subjected to accelerated ageing, were analysed and the results were interpreted by principal component statistical analysis (PCA). Results indicate that 4-hydroxybenzoic acid and dicarboxylic acids can be considered as markers of ageing, and that the use of both an iron mordant and a tannin dyestuff caused a detrimental effect on the fibres, similar to that achieved by artificial ageing. In particular, we observed the...
