Oeko-Tex^® standard 10 is widely used in the field of Textile Ecology. It aims to test harmful substances of textile products to ensure the safety of textile products. Currently, most textile products will take this standard as the reference for testing to confirm their chemical safety. C&K Testing advises companies should pay attention to this update and check whether their products conform to the latest requirements.
