Textile pH Value Testing

The pH value is a safety index of textiles, and the standard requires a pH value of 4.0 to 9.0. Higher or lower pH value not only affects the performance of the textile itself, but also may cause certain harm to human health during the use of textile. The pH of human skin is between 4.5 and 6.0, and slightly acidic can protect the skin against bacteria and viruses. If the pH of textile is too high or too low, the skin surface is easily damaged. pH value is an important indicator to ensure and improve the safety performance of textiles.

STEMart provides comprehensive pH value testing services to provide inspection reports that meet relevant regulations and international standards, thus proving the quality and safety of textile products.
