The quencher is troublesome for identifying natural dyestuffs used for coloring cloth based on the three-dimensional fluorescence spectra. Therefore, the quenching effect of Fe(II) and Cu(II) ions on the fluorescence intensity of dyed cloth has been investigated. It was confirmed by the three-dimensional fluorescence spectrum that Fe(II) and Cu(II) ions had a high-quenching effect on coloring cloth dyed with a no-mordant dye from the Amur cork tree (A) as well as with mordant dyes from Madder (B), Sappan wood (C) and Eulalia (D). The fluorescence of cloth dyed with (B), (C) and (D) using an aluminium mordant was completely extinguished by Fe(II) and Cu(II) ions. The effect of these quenchers could be efficiently removed by immersing these samples in an aqueous solution of Al(III) ions. As a result, the fluorescence is re-emitted from the samples, and this treatment makes it possible to identify these dyestuffs.
