How much do you know about the pH value of textile fabrics?

The pH value of textiles refers to the residual acid and alkali content in fabrics, which is one of the limited indicators of harmful substances that affect human health. The national standard GB18401-2010 "basic technical specification for national textile products" stipulates that the pH value of the textile products for infants and directly exposed to skin should be controlled from 4 to 8.5. The pH value of textile products that are not directly exposed to skin should be controlled from 4 to 9. If the products need to be treated in the following processing technology, the pH value can be relaxed to 4.. Between 0 and 10.5.

In general, the pH of human skin is between 5.5 and 7, and is weakly acidic. The high pH value of textiles will destroy the weak acid environment on the skin surface of the human body, cause itching, and make the skin vulnerable to other pathogenic bacteria, and even cause dermatitis and other symptoms.

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.
