Guard Against Excessive Banned Azo Dyes And Prohibited Azo Dyes In Garment Accessories

Recently, the Nantong inspection and Quarantine Bureau Integrated Technology Center was banned in the sample of sewing thread samples.

Content exceeds standard, 4- amino azobenzene content is as high as 286mg/kg, far higher than the EU 2002/61/EC directive 30mg/kg limit requirement.

Fortunately, it was confirmed by investigation that the sewing thread is only sample and has not yet been used for production.

Due to the timely discovery, enterprises have plenty of time to adjust their production plans, thus effectively avoiding them.

The finished products were returned, claimed or destroyed because of prohibited azo dyes.

Azo dyes are

A synthetic dye widely used in printing and dyeing processes. It is used for dyeing and printing natural and synthetic fibers.

Studies have shown that under special conditions, banned azo dyes may crack out carcinogenic aromatic hydrocarbons, causing direct contact with human skin lesions, and severe cases can induce cancer.

Banned azo dyes have become one of the most important quality control items in international textile and clothing trade due to their high hazard. They are also one of the most basic quality indicators of eco textiles.

Therefore, the inspection and quarantine department reminds the relevant enterprises that we must enhance awareness of risk prevention and control, strictly control the quality and safety of raw materials, and strengthen product quality control from the source. We should not only pay attention to the internal quality of the main materials, but also pay attention to the safety of accessories such as sewing thread and embroidery thread.

At the same time, we should pay attention to the understanding of the laws and regulations of importing countries, and constantly enhance their coping ability, so as to ensure that products can remain invincible in international trade.

Banned azo dyes

Not all azo dyes are prohibited, but 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.

In view of this, 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. After the implementation in April of 96, the government of Holland also made similar legislation in August of 96. The French and Australian Leah are drafting similar legislation. China's AQSIQ also drafted "textile basic safety technical requirements" in 2002.

。

Since the German government promulgated the ban on some dyes in July 15, 1994, the world's dye industry 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", domestic

It is urgent to intensify the technological development of alternative products.

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 or the products imported from third countries on the 15 member states of the EU will contain 22 azo dyes with carcinogenic aromatic amines, which must not exceed 30 * 10-6.

In January 6, 2003, the European Commission further issued the third order of 2003 to stipulate textiles, clothing and

It is forbidden to use and sell chromic azo dyes on the products market and will take effect in June 30, 2004.
