Recently, Xiaoshan Inspection and Quarantine Bureau successfully returned a batch of chemical fiber knitted women’s T-shirts imported from France, a total of 80 pieces. On-site sampling testing of the above-mentioned clothing found that the pH value was 9.4, which did not meet the requirements of my country’s mandatory standard GB18401-2010. According to the relevant provisions of the “Standardization Law of the People’s Republic of China” and the “Regulations on the Implementation of the Standardization Law of the People’s Republic of China”, the import and sale of products that do not meet the above standards are prohibited. After communication and negotiation between the trade importers within its jurisdiction and foreign businessmen, the Xiaoshan Inspection and Quarantine Bureau implemented a return process for this batch of goods.
The pH value in textiles refers to the residual acid and alkali content in the fabric. It is one of the limited indicators of harmful substances that affect human safety and health. The national standard GB18401-2010 “National Basic Safety Technical Specifications for Textile Products” stipulates that the pH value of textile products for infants and young children (category A requirements) should be controlled between 4.0 and 7.5, and the pH value of textile products in direct contact with the skin (category B requirements) should be controlled between 4.0 and 7.5. 4.0 ~ 8.5. The pH value of textile products that are not in direct contact with the skin (Category C requirements) should be controlled at 4.0 ~ 9.0. If the product requires non-final products that must undergo wet treatment in the subsequent processing process, the pH value can be relaxed to 4.0 ~ 10.5 between.
Normally, the pH value of human skin is between 5.5 and 7.0, which is slightly acidic. If the pH value of textiles exceeds the standard, it will destroy the weakly acidic environment on the surface of human skin, cause itching, make the skin susceptible to other pathogens, and even cause symptoms such as dermatitis. In addition, high or low pH value of textiles will make the fabrics susceptible 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 inseparable from the quality of the textile products themselves.
Here, Xiaoshan Inspection and Quarantine Bureau reminds relevant enterprises that imported textiles must comply with the requirements of my country’s technical specifications. Before importing a product, you must first understand the national mandatory standards of the product, strengthen communication with customers, and sign relevant product quality compliance agreements to prevent the inflow of substandard products and avoid unnecessary economic losses caused by trade disputes. loss.
