New clothes PH value easily exceed the standard should be washed before wearing

Buy a new clothes and then wear your personal clothes PH value of more than 7.5, is a substandard product. What does PH mean?

The director of the Testing Center of China Textile Industry Association stated that in the production process of clothing, dyes, auxiliaries and other chemical agents need to be added during the production process of printing and dyeing, and the rinsing is insufficient in the post-processing process, causing the occurrence of PH value and standard value. Divergence, resulting in improper acid and alkali of clothing, will result in the destruction of the skin's natural barrier, the body's own neutral acidic skin is stimulated, resulting in burning sensation, breeding bacteria, causing disease. Therefore, the State has established the standards of 18401 and other standards, the PH value of textiles in category B that directly touch the skin should be between 4.0 and 7.5, and the PH value of textiles in category C that does not directly contact the skin should be in the range of 4.0 to 9.0, and then people wear it. Most comfortable.

The director said that there are many reasons for the excessive PH value of garments, but fabrics are not fully washed and dried after printing and dyeing. At the same time, they have not taken certain neutralization measures. This is the main reason for the unsatisfactory PH value. It will cause the PH value to exceed the standard. "After buying new clothes, especially children's clothing, infants and children's clothing, do not wear it directly. If you want to wear it after rinsing it with clean water, you can reduce the harmful substances in the clothes so that the PH value does not deviate from the standard range as much as possible." said the director. .

In addition, excessive formaldehyde is also a big problem. "Formaldehyde is too high, and clothes don't necessarily smell." The director said that in order to make clothes smoother, more crease-resistant, and more solid in color, formaldehyde is often used as a preservative and in the production and processing processes such as printing and finishing. When thickeners are added, they will cause harm to human skin and body when the residual components reach a certain value. However, if they exceed the standards, they can only be detected by the instrument. Prolonged use of textiles with excessive levels of formaldehyde can cause chronic respiratory diseases, conjunctivitis, pharyngitis, asthma, bronchitis, etc. Severe cancers may be induced. Children like to chew and suck on textiles and may directly produce toxic reactions.
