The consequence of over-expending of PH value of textiles is so serious. Do you know?
The over-expendation of PH value of textiles can damage the weak acidic environment of human skin, cause itching, and make the skin easily damaged by other bacteria, and even cause dermatitis and other symptoms. So what kind of PH value do you know are qualified? What is the PH value of textiles? PH value of textiles refers to the residual acid and alkali content in fabrics, and it is one of the quantitative goals of harmful substances that affect human health and health. What is the relationship between pH and us? The skin of the human body usually has a pH of 5.5 to 7.0 and is weakly acidic. If the PH value of the textile is alkaline, then the pH of the skin surface will be destroyed after contact with the body, resulting in the health of the skin. After the skin loses its protective function, the bacteria can easily enter the body. In addition, the high or low PH value of the textile can make the fabric easily damaged during storage. This shows that the PH value of textile products is not only closely related to the health of consumers, but also inseparable with the quality of textile products. Reasons for PH overrun There are many reasons for PH overruns. However, after the fabrics are dyed and processed, the fabrics are not fully washed and dried, and they have not adopted a certain neutralization method. This is the main reason for the formation of unsatisfactory PH values. In addition, residual fabrics, etc. will also form a pH overrun. How much is the PH value of textiles? National regulations GB18401-2010 "National Textile Products Safety Standard Specification" rules, infants and children directly touch the skin of the PH value of the textile products should be controlled at 4.0 to 8.5, non-straight touch the skin of textile products PH value should be controlled at 4.0 ~ 9.0. If the product requires non-final products that require wet disposal in subsequent processing techniques, the PH can be relaxed to between 4.0 and 10.5. Finally, we must remind everyone to buy back new products, especially children, baby products, underwear and other textile products that touch the human body directly. Do not wear them directly. It can be used after rinsing with fresh water, which can effectively reduce harmful substances in textile products, so that the PH value does not violate the standard scale as much as possible. polyester viscose, tr fabric,tr suiting fabric, tr woven fabric dyed printing fabric, tr checks fabric,Uniform Fabric Shaoxing City Shengfeng Import And Export Co.,Ltd. , https://www.sunfeelfabric.com
