Usage

Description

Vat Blue 43 is a red light blue to red light navy blue dye that is used in various applications due to its properties and performance standards.

Uses

Used in Textile Industry:
Vat Blue 43 is used as a dye for coloring textiles. It is known for its ironing fastness, chlorine bleach resistance, light fastness, and oxygen bleach resistance. It also has good soaping and fading properties.
Used in Mercerized Textiles:
Vat Blue 43 is used as a dye for coloring mercerized textiles, which are treated with a caustic soda solution to increase their luster and strength. The dye provides good ironing fastness, chlorine bleach resistance, light fastness, and oxygen bleach resistance for these types of textiles.
Used in Stain Resistance:
Vat Blue 43 is used as a dye to provide stain resistance to textiles. It has good performance in terms of ironing fastness, chlorine bleach resistance, and oxygen bleach resistance, making it suitable for textiles that need to be resistant to stains.
Standards:
Vat Blue 43 meets the performance standards set by ISO and AATCC, ensuring its quality and reliability in various applications.

Preparation

3-(4-Hydroxyanilino)carbazole in 107 ℃ in Butanol sodium polysulfide solution reflux heating 24 hours, and then with sodium nitrite short time heating, steam out of Butanol, through the air and add salt to make dye completely precipitated out. This indophenol is by carbazole and nitroso phenol in concentrated sulfuric acid in – 20 to 23 ℃ condensation, then reduction and have to (BIOS983, 71 -74). To cure solution is to add 3 – methyl – 4 ‘- hydroxy – 4 -aminodiphenylamine, 4, 4’ – dihydroxydiphenyl aniline and phenol , improved the performance of the dye (BIOS983, 75- 81). Note: use with C.I. leuco sulfur dye similar method, some the structure of the dyes can be converted into the leuco compound.
