| Abstract: | Combining dyeing and wrinkle‐resistance finishing of cotton in a one‐step process using a hemicyanine fluorescent dye DHEASPBr‐C2 was investigated in this paper. Fourier transform infrared spectroscopy, a fixation test, extraction with boiling N,N‐dimethylformamide, and a colour fastness test certified that DHEASPBr‐C2 was linked to the cotton fibre through covalent bonds. The results showed that dyed cotton fabric using DHEASPBr‐C2 had an obvious fluorescent effect in the range 550–700 nm, and the emission peak location was 588–590 nm. In addition, the dyed fabric met the EN471:2003 standard for chromaticity and could be used in high‐visibility warning clothing. |
