How Much Do You Know About Clothing Safety Level?

According to a test report of Shanghai Quality Supervision Bureau, some of the products of the international fashion retail chain giant H&M were unqualified, and the value of a T-shirt exceeded the standard. The famous clothing brand was once again involved in the "quality gate".

Each of us has intimate contact with clothes every day. Those seemingly clean and beautiful clothes sometimes become "invisible killer" threatening our health.

In fact, clothing also has a safety grade, and the state has corresponding review standards. Do you know that?

Do you know the safety grade of clothing?

Clothing also has

All of this sounds a bit distant from the consumers, but it can be seen from the clothing label.

The national basic safety technical specification for textile products also clearly stipulates that labels, labels, labels or instructions for all garments and decorative textiles sold on the market should be clearly marked with product classification and labels should not be handwritten or altered.

In January this year, the relevant state departments also issued new standards, requiring clothing manufacturers to mark formaldehyde content and pH value. This is the two chemical substance that can be most harmful to human body in clothing ingredients.

Therefore, when buying clothes, consumers should pay special attention to the relevant labels on the labels.

Why do clothes contain dangerous ingredients?

The quality is not up to standard.

At present, according to the national mandatory technical standards, the indicators for testing clothing mainly include pH value, formaldehyde content, azo dye, color fastness, fiber content, plocation and so on.

In the process of garment manufacture, some chemicals are unavoidable. If the chemicals are not treated well, the content of these chemicals on textiles exceeds a certain standard, if they are directly exposed to the skin, they will do harm to people's health, and some of them will still have a long incubation period.

We may have access to:

PH value.

The pH value is closely related to the processing technology and quality control of fabrics.

The failure of pH value is mainly due to the use of a large number of acid and alkali substances in the dyeing and finishing process of fabric production enterprises, and no reasonable neutralization treatment process has been taken, resulting in excessive pH value of the products.

The normal pH of human skin should be between 5.5 and 7, which is slightly acidic. It can protect the body from infection by bacteria.

If the pH value of clothing is high or low, it will directly damage the balance mechanism of human skin and weaken the skin's ability to resist the invasion of germs, which may cause skin allergies, itching, redness and swelling, and even trigger irritant dermatitis and contact dermatitis.

Formaldehyde content.

When clothing is produced, it will add formaldehyde to auxiliaries in order to achieve the functions of crease prevention, shrinkproof, flame retardancy, or to maintain the durability of printing and dyeing or to improve the handle.

In particular, some garment manufacturers in order to save costs, in the production of ironing clothing, in order to make the fabric is not easy to wrinkle, the use of formaldehyde finishing agent.

When the residual formaldehyde is not treated and made into garments, it will do harm to the human body.

Formaldehyde will gradually release in the process of wearing, combined with human sweat or hydrolyze to produce free formaldehyde, which will produce strong stimulation on respiratory mucosa, eyes and skin, causing dizziness, airway inflammation and skin inflammation, which can cause hematological diseases and even cancer.

Azo dyes.

Azo dyes are common in clothing dyeing.

Color fastness.

Color fastness refers to the degree of firmness of dyed garments.

Clothing with unqualified color fastness may stain stains on other clothing while washing clothes, and dyes can also be easily pferred from textiles to human skin, which is likely to cause harm to human health.

At the same time, when dyeing or washing, the dyes and finishing agents that fall off due to poor color fastness will be discharged into rivers with waste water, and will also have adverse effects on the ecological environment.

Authoritative tips

If the formaldehyde and pH value of clothing components are indeed exceeded, it is very difficult for consumers to make a correct judgement without passing the testing apparatus. In this regard, Yang Ping, deputy director of the China Textile Industry Association's testing center, pointed out the following solutions that are convenient for you to operate.

1. when consumers buy Textiles and clothing products, it is best to buy them in regular stores, where goods need to be submitted to the test report before they are allowed to go public, and the overall safety is guaranteed.

2., pay attention when buying.

3. pay special attention to the special odors emitted from some textile products, such as mildew, gasoline and kerosene, fishy smell, especially those newly opened. This indicates that there are excessive chemical residues on the textiles.

4. generally speaking, everyone will clean the newly bought underwear. In fact, as long as new clothes (especially T-shirts, shirts and other direct contact with the skin), regardless of the price level, should first wash and wear, and then in the sun.

Assuming that pH exceeds the standard, cleaning will be very helpful.
