< p > < a target= "_blank" href= "http://www.91se91.com/" > textile > /a > a target= "_blank" href= "_blank" > clothing < < > Zhang Peng, engineer of product quality supervision and inspection center, said "azo dyes": "its toxicity is stronger than that of food dye Sudan."

Azo dyes, also known as decomposable aromatic amine dyes, are synthesized from 23 carcinogenic aromatic amines as intermediates.

At present, such dyes are widely used in the world, and there are about 360 kinds of dyes.

These dyestuffs are used for dyeing < a target= "_blank" href= "http://www.91se91.com/" > cloth < /a > dyeing, especially when the underwear is dyed. When it is directly contacted with human skin, its toxic components will be absorbed and diffused by the skin. Under special conditions, 20 kinds of carcinogenic aromatic amines can be decomposed, and the DNA structure of human body can be changed through activation, causing lesions and inducing cancer.

< /p >

< p > in these toxic dyes, the most toxic is benzidine.

Benzidine is an important intermediate in the dyestuff industry. Benzidine and its salts are strong carcinogens, which can lead to bladder cancer, ureteral cancer and pyelonephrosis.

That is to say, when we dress happily in the shop, the clothes may be sending terrible carcinogens to our bodies.

< /p >

< p > more frightening is azo dye induced cancer incubation period is very long, can be up to 20 years.

According to Zhang engineer, "bladder cancer today is probably caused by a benzidine containing" a "target=" _blank "href=" http://www.91se91.com/ "> 20 years ago.

At that time, people may not know who to go to complain.

From the legal point of view, who can prove that your bladder cancer has something to do with this dress?

< /p >

"P", as consumers, is even more frightening. These toxic dyes can not be detected at all.

It can not see, can not smell, can not wash, can not burn, like devil like in the clothes, everywhere, everywhere devour your life.

Dr. Ruan Wenhong, an associate professor at the Institute of materials science, School of chemistry and chemical engineering, Zhongshan University, said that these toxic dyes are far more powerful than formaldehyde, because formaldehyde is odorous, easily distinguishable and soluble in water.

When consumers buy clothes, they usually remove most of the formaldehyde by washing with water, but decomposable aromatic amine (azo dye) is not only insoluble in water, but also indistinguishable from the appearance of textiles.

< /p >

< p > there is already a scientific conclusion about the cancer caused by such toxic clothing dyes.

According to relevant data, as early as nineteenth Century, the number of bladder cancer caused by occupational exposure to azo dyes in western developed countries reached more than 3000.

The German health department has found a significant increase in the incidence of bladder cancer in people using this kind of dye.

Moreover, a large number of medical surveys show that the incidence of bladder cancer is often 28 times that of the normal population.

In this regard, all countries in the world have formulated laws prohibiting the use of such toxic dyes.

In 1994, Germany promulgated the regulations prohibiting the use of azo dyes in textiles. The EU implemented the directive on the prohibition of the use of azo dyes in 2003. Our country has implemented mandatory standards since January 1, 2005, and banned the production, sale and import of textiles containing such dyes.

< /p >

< p > however, recently, the quality inspection department found that about 6% of the samples of 20 well-known brands 1051 samples of garment fabrics were found to contain azo dyes. The most serious case was 190 times the standard, and the active inspection of famous brands is still the case. As for those unknown brands, the content of textiles produced by small and medium-sized enterprises can be imagined.

< p > not all azo dyes are prohibited. Only 24 kinds of aromatic amine azo dyes designated by legislation are released after reduction, about 130 species.

These banned dyestuffs dyed clothing or other consumer products will be mixed with human skin for long term. They will be mixed with the released components in the metabolic process and produce a reduction reaction to form carcinogenic aromatic amine compounds. This compound will be absorbed by human body. After a series of activation, the structure and function of DNA in human cells will become the inducement of human diseases.

< /p >

In 1994, the German government formally banned the use of certain azo dyes for long-term consumption of skin products in the "food and consumer goods" regulations. In April 96, the government of Holland also made similar legislation in August of 96. France and Australia are drafting similar legislation. China's AQSIQ also drafted the national standard of "textile basic safety technical requirements" in 2002.

< /p >

< p > since the German government promulgated the prohibition of partial dyes act in July 15, 1994, the dye industry in the world has been working on the prohibition of dye substitutes.

With the continuous improvement of environmental and ecological protection requirements, the scope of banned dyes has been expanding.

The EU has banned banned azo dyes in recent years. Once the ban comes into force, the impact of such a big exporter of textiles and clothing is self-evident.

Facing the aggressive "green barrier", it is urgent for the domestic dyestuff industry to intensify the technological development of substitute products.

< /p >

In September 11, 2002, the European Commission issued sixty-first decree prohibiting the use of azo dyes that decompose 22 kinds of carcinogenic aromatic amines under the condition of reduction, and stipulates that after September 11, 2003, the products produced by the European Union in the 15 member states of the European Union or the products imported from third countries will contain 22 azo dyes with carcinogenic aromatic amines, and the content of the 22 azo dyes that can be decomposed will not exceed 30 * 10-6.

< /p >

< p > January 6, 2003, the European Commission further issued the third order of 2003, which prohibits the use and sale of chromic azo dyes in the EU's textile, clothing and leather products market and will take effect in June 30, 2004.
