After long-term contact with human skin, clothing containing prohibited azo dyes will mix with components released during metabolism and undergo a reduction reaction to form carcinogenic aromatic amine compounds. This compound will be absorbed by the human body and become a trigger for human diseases p> Dyes are classified according to their structure, including azo dyes, nitro dyes, sulfide dyes, anthraquinone dyes, etc. In the molecular structure of dyes, those containing azo groups (- N=N -) are collectively referred to as azo dyes, where the azo group is often connected to one or more aromatic ring systems to form a conjugated system and serve as the chromophore of the dye p> Azo dyes are widely used in dyeing and printing of textiles, leather products, etc. Azo dyes have a wide chromatographic range, including red, orange, yellow, blue, purple, black, etc. They have a complete range of colors, good shade, and a certain degree of fastness. Therefore, they are widely used in the dyeing of various fibers p> AZO azo detection It is commonly used for AZO azo detection in clothing/fabrics, or other textile products. The GST quantity is far from azo detection, with years of service quality p> AZO refers to a type of dye in clothing and textiles. Azo is the substance that forms the basic color in the dye. If the azo structure is discarded, most of the basic colors of the dye will not be generated. A few azo structured dye varieties may produce the following 24 carcinogenic aromatic amine substances during chemical reaction decomposition, which are prohibited by the European Union. These prohibited azo dye varieties account for about 5% of all azo dyes, and not all azo structured dyes are prohibited. With the increasing improvement of living standards, the quality requirements for clothing and textiles are becoming increasingly strict. Due to the fact that prohibited AZO azo dyes (or decomposable aromatic amine dyes) can decompose into carcinogens, seriously affecting physical health; Moreover, this type of dye is usually colorless and odorless, and cannot be perceived by the human sensory organs, or even reduced in harm through washing or other methods. Therefore, foreign textile standards prohibit this type of dye p>   p> AZO azo detection products; Clothing, bedding, towels, wigs, fake eyebrows, hats, diapers, and other cleaning and hygiene items, sleeping bags ; Shoes, gloves, watch straps, handbags, various wallets, briefcases, chair covers; Textile or leather toys, toys with textile or leather clothing, synthetic dyes, organic compound dyes; Testing standards for fabrics and yarns used by consumers EN14362-1:2012, EN14362-2:2012 GB/T 17592-2006 BS EN ISO 17234-1-2010 The EU has officially announced three European standards for testing methods for harmful azo dyes. These standards are the supporting documents for implementing EU Directive 2002/61/EC, which are: 1: CENISO/TS17234:2003 Leather - Chemical testing - Inspection of dyed leather for a certain type of azo dye 2: EN14362-1:2003 Textiles - Inspection of aromatic amines released by azo dyes - Part 1: Testing products for a certain type of azo dye without extraction 3: EN14362-2: 2003 Textiles - Inspection by Aromatic amines released from azo dyes - Part 2: Extracting fibers to test whether the product contains a certain type of azo dye p> AZO (azo dye) Test items: Serial number Aromatic amine CAS No. 1 4-aminobiphenyl 92-67-1 2 Benzidine 92-87-5 3 4-chloroo-toluene 95-69-2 4 2-naphthylamine 91-59-8 5 p>o-aminodimethylazobenzene97-56-3 6 2-amino-4-nitrotoluene 99-55-8 7 p-chloroaniline 106-47-8 8 2, 4-diaminobenzene_ p> 615-05-4 9 4, 4 'aminodiphenylmethane 101-77-9 10 3, 3 '- Dichlorobenzidine 91-94-1 11 3, 3 '- Dimethoxybenzidine 119-90-4 12 3, 3 '- Dimethylbenzidine 119-93-7 13 3, 3 '- Dimethyl-4,4' - diaminodiphenylmethane 838-88-0 14 3-Amino para toluene methyl ether (p-Klee tincture) 120-71-8 15 4,4 '- methylene bis - (2-chloroaniline) 101-14-4 16 4,4' - diaminodiphenylether 101-80-4 17 4,4 '- diaminodiphenyl sulfide139-65-1 18 o-toluidine 95-53-4 19 2,4-diaminotoluene 95-80-7 20 2,4,5-trimethylaniline 137-17-7 21 o-methoxyaniline 90-04-0 22 4-aminoazobenzene 60-09-3 The above article is a partial list for more detection needs Free consultation with online consultants for details: 1520 173 3840 (phone and WeChat), conducting testing on over a hundred inspection websites - issuing authoritative testing reports has legal effect P> Function of testing report:1.
