Introduction and analysis of banned azo dyes in 24 kinds of textiles

Information Sources: / 2019-07-09 15:05:29 / Click:

The so-called azo dye is a dye containing azo groups in its molecular structure. The azo groups are often one or more aromatic ring systems connected to form a conjugated system as a dye color body, which is distributed in almost all colors. Therefore, not all azo dyes are banned, and only azo dyes (especially the aniline series) that release the standard 24 types of aromatic amines specified in the regulations are released. When these garments or other consumer products that are banned from the production of azo dyes are in contact with human skin, they will be mixed with the components released by the normal metabolism of the human body to produce a carcinogenic aromatic amine compound, which becomes a cause of cancer in human body.
