The human - ecological safety of textiles refers to the impact of textiles on the wearer, user, and their immediate environment. As products that have the closest daily contact with the human body, textiles have a significant impact on human health. Products tested and certified by Oeko - Tex Standard 100 are guaranteed not to cause harm to human health. More importantly, this certification can effectively avoid trade barriers in the EU, North America, and other countries, helping Chinese manufacturers successfully enter the high - end markets in Europe and the United States.
