In the production process, a large amount of alkali, pH adjuster, surfactant, etc. are required from the aspects of fading, scouring, bleaching, dyeing, printing, etc. If the cleaning is not thorough, acid and alkali residues will be caused. Lead to excessive pH.
Excessive residue will cause strong irritation to our skin, destroying the pH of the skin surface. In severe cases, it will cause skin irritation and induce symptoms such as dermatitis, which will cause great harm to the body.
Strict control of textile pH not only ensures product quality, but also protects our health!
Let us first understand the pH value of the textiles stipulated by the national standard. The pH standard specified in the National Textile Products Basic Safety Technical Specification is pH ≤ 7.5 for Class A infant products; the pH value of Class B textiles directly contacting the skin is 4.0 ～ 8.5; Class C textiles that are not in direct contact with the skin have a pH of 4.0 to 9.0. Choose an efficient and convenient pH meter product to make your testing easy.
