How Much Is The Ph Value Of Fabric?

Recently, Nantong A number of unqualified light textile products were detected by the Development Office of the State Administration of inspection. A textile company in Nantong plans to export embroidered sheet sets to Egypt. Our Bureau inspectors strictly follow the requirements of the Jiangsu import and export light textile products inspection and supervision regulations, and send the representative samples to the lab. in accordance with the national basic safety technical specification for textile products (GB18401-2010). The pH value of the test is 3.8, which exceeds the standard range.

The pH value of textiles refers to the residual acid and alkali content in fabrics, and it is one of the limited indicators that affect the safety and health of human body. The national standard GB18401-2010, the basic technical specification for national textile products, stipulates that the pH value of textile products for infants and children directly exposed to the skin should be controlled at 4 to 8.5, which is not directly related to the skin. Textile products PH The value should be controlled between 4 and 9. If the product needs to be wet treated non final products in subsequent processing, the pH value can be relaxed to 4 to 10.5.

The skin of the human body is in general condition. PH value Between 5.5 and 7, it is weakly acidic. The excessive pH value of textiles will damage the weak acidic environment of human skin surface, cause itching, and make the skin vulnerable to other pathogens and even cause dermatitis.

In addition, the high or low pH value of the fabric will make the fabric easy to damage 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 closely related to the quality of textile products.

Therefore, Nantong State Inspection Bureau reminds consumers that when buying textile products, they must first see clearly the information in the product tag, and try not to buy low quality products. According to the classification of basic safety technical specifications for national textiles, textile products can be divided into three safety levels: A, B and C, that is, infants and young children (36 months or less) should meet the technical requirements of class a products. Products directly exposed to skin should meet the technical requirements of B products. The products that are not directly exposed to skin should meet the technical requirements of C products. For textile products labeled "C" or "qualified", it is best to buy them carefully. Secondly, after buying new products, especially children, baby products, underwear and other textile products directly contacting the human body, do not wear them directly. It can be washed with water and then worn again, so that the harmful substances in textile products can be effectively reduced, so that pH value can not deviate from the standard range as far as possible.
