Abstract:
In this study,indigo-dyed cotton and silk textiles were subjected to simulated aging treatments by ultraviolet light(UV)and hydrochloric acid solution(pH=2)according to the potential preservation environments of ancient textile cultural relics.Scanning electron microscope(SEM)was used for microstructural observation of the simulated textiles,and a combination method of ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS)and portable Raman spectroscopy(P-RS)was developed for detection of indigo dye in cotton and silk textiles before and after aging.The results revealed that,in silk samples after UV aging and acid aging,the indigo dye along with isatin which was the indigo degradation product could be detected by UPLC-Q-TOF-MS,while in cotton samples after UV aging and acid aging,the signal of isatin was less prominent although the characteristic peaks of indigo were detectable.However,the characteristic signals of indigo in both UV-aged and acid aged textiles could be effectively detected by P-RS,which provided a quick and convenient method for detection of indigo dye in textiles.Compared with UV aging and acid aging,acid-aged samples exhibited a more robust signal response to indigo dye,offering a rapid and non-destructive method for indigo detection.The developed UPLC-Q-TOF-MS and P-RS methods could be used in efficient and rapid identification of indigo dye,which hold potential in the preservation and restoration of ancient textile cultural relics.
