WebIndigo, madder, cochineal, turmeric, tannin-producing plant, and young fustic were identified as sources of dyes in textiles. Scanning electron microscopy with energy-dispersive X-ray detector (SEM-EDS) and Fourier transform infrared spectroscopy (FT-IR) were used to identify and characterize fibres and mordants in funeral gowns. WebJun 25, 2024 · This is rationalized by assuming that the 2041 nm peak contains spectral contribution from both NH 2, urea, and urethane, while the 1485 nm peak is only contributed by urea or urethane. If this assumption is true, the fast reaction between iso and water and the sequential nature of the reactions shown in Fig. 6 would lead to such interesting …
