The General Administration has 4 kinds of products, such as soy sauce, vinegar, sauce, children and infant clothing.

Spot checks were conducted, among which 14 products were found to be out of standard for children and infant clothing, including famous brands such as Babu bean and E-COLETTE.

The two children's clothing brands in Beijing are listed on the black list, which are produced by Beijing Ying Fang daily plastic products Co., Ltd. "baby side Xi" shoulder open suit and "water boy" produced by Beijing Carmen Clothing Co., Ltd.

The reasons are that the fabric's pH value is unqualified and the ingredient and content of lining material are not qualified.

[exposure interpretation]

Buy new clothes and wash them before wearing them.

Your personal clothing has a pH value of more than 7.5, which is an unqualified product.

What does pH mean?

Yang Ping, deputy director of the China Textile Industry Association's testing center, said that in the production process of clothing, various chemicals such as dyes and auxiliaries should be added to the production process such as printing and dyeing. If the rinsing is not enough during the whole process, the pH value deviates from the standard value, resulting in improper acid and alkali of the clothing, which will cause the natural barrier of the skin surface to be damaged, and the skin of the human body itself is stimulated to produce burning sensation and bacteria, causing diseases.

Therefore, the state has drawn up the 18401 level standard. The pH value of textiles directly exposed to B should be between 4 and 7.5. The C value of textiles that are not directly exposed to skin should be in the range of 4 to 9, when people wear the most comfortable.

Yang Ping said that there are many reasons why the clothing value exceeds the standard. However, after the printing and dyeing process, the fabric is not fully washed and dried, and at the same time, it does not take certain measures to neutralize it. This is the main reason for the failure of the pH value. Inferior fabrics will also cause the pH value to exceed the standard.

"After buying new clothes, especially children's clothing and infant clothing, do not wear them directly, rinse them with water and then wear them. They can reduce harmful substances in clothes and keep pH value as far as possible."

Yang Ping said.

In addition, formaldehyde exceeding standard is also a big problem.

"Formaldehyde is beyond the standard, not necessarily smell of clothes."

Yang Ping said that in order to make clothes more smooth, crease resistant, stronger colors, printing and dyeing and finishing processes, formaldehyde is often added as preservatives and thickeners. When the residual components reach a certain value, it will cause harm to human skin and body, but it can only be detected by instruments.

Long term use of formaldehyde beyond the standard of textiles can cause chronic respiratory diseases, conjunctivitis, laryngitis, asthma, bronchitis, etc., which can cause cancer seriously, children like to chew and suck textiles, and may also directly produce toxic reactions.
