In terms of literal meaning, this kind webbing needs to be able to stand the test of the inspection center. Manufacturers can use the health, green, and hygienic cotton raw materials to do the cotton belt through the relevant department certification. The second is that the machine that produces the environmental protection webbing also needs to meet the above condition. Only these conditions can be recognized as the environmental protection ribbon. Then how can manufacturers and textile appraisal associations identify whether this webbing is environmentally friendly?
1, PH value
The surface of human skin is weakly acidic, and the pH of the textile directly in contact with the skin should be between weakly acidic and neutral. It will not cause skin itching, and will not damage the weak acidic environment of the skin surface.
2, Formaldehyde
Formaldehyde is a toxic substance that is harmful to the protoplasm of biological cells through contact with the respiratory tract and skin of the human body, produces a strong stimulus to the respiratory mucosa, and causes respiratory inflammation and dermatitis.
3, Heavy metal
The cumulative toxicity of heavy metals on the human body is quite serious. When the heavy metals in the affected organs accumulate to a certain extent, it will cause certain harm to health.
In China, currently there are 13 associations that test environmental protection webbing. Their task is to detect the harmful substances in the webbing and determine their safety. The Oeko-Tex Standard 100 is now the most widely used textile eco-label. The standards set by Oeko-Tex Standard 100 are based on the latest scientific knowledge and limit the content of harmful substances in yarns, fibers and various types of textiles. Only manufacturers that can provide proof-of-warranty quality guarantees through strict inspection and inspection procedures are allowed to use on their webbing products. Therefore, webbings that have been subjected to such strict tests can all be called eco-friendly webbings.
