Low Price Azo Dyes Are Banned Repeatedly In Textile And Leather Production.

A few days ago, the Guangdong provincial industrial and commercial bureau announced the first batch of defective commodities involving dangerous personal and property safety this year, including bedding, toys, children's cars, air conditioners, clothing and so on, totaling 53.

Among the defective products, 26 bedding and 10 clothing items, half of which were found to be decomposed carcinogenic aromatic amine dyes.

Some consumers spend hundreds of yuan or even thousands of dollars on brand-name clothes and bedclothes, but they are not as safe as they think.

How should consumers choose comfortable products?

The decomposable aromatic amine mainly comes from azo dyes in clothing.

It is understood that the dye is used by many small and medium-sized textile and garment production enterprises in textile, clothing, leather products, household cloth production, mainly for two reasons: price and source.

Most of the green dyestuffs used to replace the decomposable aromatic amine dyes are imported and the price is 3~4 times higher.

Azo dyes are easy to produce, low in price, full in color, strong in coloring, bright in color, and high in color fastness. Compared with environmental dyes, manufacturers are more willing to choose azo dyes.

According to the experts, from the point of view of textile safety, the toxicity and carcinogenicity of decomposable aromatic amine has far exceeded that of formaldehyde.

Because formaldehyde is pungent, easily distinguishable, and soluble in water, consumers can buy most of the formaldehyde after washing the fabric.

However, the decomposition of aromatic amine dyes is not acceptable.

After decomposing aromatic amine dyes into clothes, it is not only insoluble in water, but also colorless and tasteless, and can not be eliminated.

At the same time, it can not be distinguished from appearance, and can only be detected by technical means.

Under certain conditions, azo dyes can decompose and restore more than 20 aromatic amines with carcinogenicity. After prolonged contact with the human body, the harmful ingredients of the dye will be absorbed by the skin and spread in the human body.

In addition to harmful to human health, in the production of "banned azo dyes" process will also be a large number of sewage, which can cause serious environmental pollution.

How to avoid decomposable aromatic amines

Experts say, first, look at the appearance.

To see if the product has a complete identity, including product use instructions, durability labels, whether the manufacturer's name, address, telephone, product name, product size, specification, and number are clearly specified. The ingredients and contents of raw materials, washing methods, product standard numbers, product quality levels, and product quality inspection are used.

And the categories of safety technology must be marked.

At the same time, to see whether the products are good workmanship; two is to smell the smell, you can smell the product at short distance whether there is a pungent odor, especially the product of folded belt packaging.

If there is a pungent odor, be vigilant. The product may exist.

There are quality problems such as odors and so on. The three is to keep vouchers, and try to keep all the credentials related to the commodity as far as possible after purchase, including purchase of bills, clothing tags, etc., which can be used as an important evidence for safeguarding rights in quality disputes.

In addition, the new clothes and bedclothes should be washed and reused before being washed. They should not be washed after being exposed to sunlight, so that the concentration of harmful substances can be reduced to the maximum.
