Uses

Used in Textile Industry:
Sodium 4-chloro-3-[4-[[2,2'-dimethyl-4'-[[4-[(phenylsulphonyl)oxy]phenyl]azo][1,1'-biphenyl]-4-yl]azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulphonate is used as a dyeing agent for wool and silk fabrics due to its good levelness and medium discharge properties.
Used in Dye Application:
sodium 4-chloro-3-[4-[[2,2'-dimethyl-4'-[[4-[(phenylsulphonyl)oxy]phenyl]azo][1,1'-biphenyl]-4-yl]azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulphonate is used as a dye in the dyeing process, providing a yellow color to the fabric. It is particularly effective in dyeing with copper or chromium ions, which results in a lighter shade.
Standard:
The standard for this dye includes the following properties:
Light Fastness: Rated 4-5, indicating moderate to good resistance to fading under direct sunlight.
Soaping: Rated 4-5, suggesting that the color maintains its intensity after soaping, which is a process used to remove excess dye from the fabric.
Perspiration Fastness: Rated 4-5, meaning the color is resistant to fading due to sweat.
Oxygen Bleaching: Rated 4-5, showing that the color does not fade significantly when exposed to oxygen during the bleaching process.
Fastness to Seawater: Rated 2, indicating poor resistance to fading when exposed to seawater.
These ratings provide a comprehensive understanding of the dye's performance and stability under various conditions, making it easier for textile manufacturers to select the appropriate dye for their specific applications.
