摘要：

Abstract— The photo‐oxidation of wool and silk treated with a fluorescent brightening agent (a triazinylstilbene) has been studied. Complete amino acid analyses of the irradiated keratins showed that in the presence of this sensitizer, only tryptophyl and histidyl residues were susceptible to photodecomposition; the former were oxidized at a faster rate than the latter. Sixty per cent of the tryptophyl residues in silk were photo‐oxidized during a 4 hr exposure to an artificial light source designed to simulate summer sunlight conditions. The rate of discoloration of the irradiated silk fabric, measured spectrophotometrically, was found to parallel closely the rate of photo‐oxidation of the tryptophyl residues in the fabric.
