In chemistry, pH (Potential Hydrogen) is a measure of the acidity or basicity of an aqueous solution. Pure water is neutral, with a pH close to 7.0 at 25 °C (77 °F). 澳门银河娱乐电子游戏网址s with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline.

Regulations

• Oeko-Tex®Standard 100
• China GB 18401 National General Safety Technical Code for Textile Products
• China GB/T 18885 Technical Specifications on Ecological Textiles
• Environmental standards
• Other related standards

Textiles shall undergo fixation, reduction and washing in its production during desizing, scouring or bleaching, dyeing (printing). These processes consume large amounts of soda ash, caustic soda, surfactants, etc. It will lead to acid or alkali residue if the laundering process is not thorough. The pH value of the textiles, determined by the pH value of the textile extract, is the technical index to control the pH value in the production process.

Either extreme of pH value in textiles (beyond the pH range that the skin can tolerate) may lead to irritation and corrosion to skin causing scytitis. It may even do damage to sweat gland and neuro systems.
