As per the new standards, pH value of clothing directly in contact with skin is required to be between 4.0 ~ 7.5, while pH value for clothing not in direct contact with skin is supposed to be between 4.0 ~ 9.0.
With regards to formaldehyde content, the national standards specify that, it should not be more than 300 mg per kg with regards to suits and trousers.
With regards to labels, clothing label should include trademark, type, components and content of raw materials, washing methods, standard number of product, product quality, product grade and so on. It is not mandatory to provide details of pH and formaldehyde content in the labels.
