Abstract
Sulfadiazine, an antibacterial agent, was used in combination with the different
coupling components to synthesize three sulfadiazine-based azo disperse dyes with antibacterial
properties. The chemical structures of the synthesized dye were verified
using FT-IR spectroscopy and 1H-NMR analysis, and the spectral properties of the dyes
were analyzed using a UV-Visible spectrophotometer. Among the synthesized azo dispersion
dyes, the more hydrophobic dye exhibited superior build-up properties on PET fabrics.
The colorfastness of PET fabrics dyed with the synthesized dyes showed excellent color
fastness to washing, perspiration, and rubbing. An analysis of the antibacterial properties
of S. aureus and K. pneumoniae revealed that there was no significant antibacterial activity
compared to that of undyed PET. However, a dyeing with a higher concentration of a particular
dye produced an increase in antimicrobial properties.
