Combining dyeing and wrinkle-resistance finishing of cotton in a one-step process using a hemicyanine fluorescent dye

摘要

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.
