The OEKO-TEX® STANDARD 100 is a globally established system for the certification of textiles, leather goods and textile-related products that have been tested for harmful substances. Materials from all processing stages of the textile production chain can be certified. This applies to yarns, woven and knitted goods, accessories (e.g. zippers, ribbons, buttons) through to ready-made textiles (clothing, house and home textiles, technical textiles). The certification can thus be individually adapted to the requirements of the client and your products according to a “modular principle”.
