Excessive Ph Value Of Clothing Stimulates Skin Easily.

Recently, AQSIQ conducted a spot check on the quality of 4 kinds of products, including soy sauce, vinegar, sauce, children and infant clothing. Among them, 14 samples of children and infant clothing were found to be out of line with the standard, including the famous brands such as Babu bean and E-COLETTE.

Two children's clothing brands in Beijing are listed on the black list, which are the "baby" children's thickness produced by Beijing British daily plastic products Co., Ltd., "baby Fang Xi" shoulder opening suit and Beijing Carman Clothing Co., Ltd. Sweater 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 inspection center of China Textile Industry Association, said that in the process of garment production, printing and dyeing And other chemical agents such as dyes and auxiliaries should be added to the production process. If the rinsing is not enough during the whole process, the pH value will deviate from the standard value, resulting in improper acid and alkali in clothing, which will cause the natural barrier on the skin surface to be damaged. The skin of the human body is irritated by its neutral acidic skin, resulting in burning sensation, causing bacteria and 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, costumes PH value There are many reasons for exceeding the standard. However, after dyeing and finishing, the fabrics are dried and washed out. At the same time, some measures of neutralization are not taken. This is the main reason why the pH value is not qualified. "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.
