The pH value of textiles refers to the acid-base content remaining in the fabric, and is one of the limited indicators of harmful substances that affect human safety and health. The pH value of infants and textile products that directly contact the skin should be controlled at 4.0-8.5, and the pH value of textile products that do not directly contact the skin should be controlled at 4.0-9.0. If the product needs to be wet-treated in the subsequent processing Products, the pH value can be relaxed to between 4.0 and 10.5.
Under normal circumstances, the pH value of human skin is between 5.5 and 7.0, which is weakly acidic. If the pH value of textiles exceeds the standard, it will destroy the weak acidic environment on the surface of the human skin, cause itching, and make the skin vulnerable to other germs, and even cause symptoms such as dermatitis.
Others, high or low PH value of textiles will make the fabric easy to be damaged during storage. It can be seen that the pH value of textile products is not only closely related to the health of consumers, but also inseparable from the quality of textile products.
There are many reasons why the PH value exceeds the standard, but after the printing and dyeing process, the fabric is dried out of the factory without sufficient washing, and at the same time no definite neutralization measures are taken, which is the main reason for the unqualified PH value. In addition, inferior fabrics, etc. will also cause the PH value to exceed the standard.
After buying new products, especially children's, infant products, underwear and other textile products that are in direct contact with the human body, do not wear them directly. It can be rinsed with clean water before wearing, which can effectively reduce harmful substances in textile products, so that the pH value can never deviate from the standard range.
