May 2018 Green FC Free is a fluorine-free hydrophobisation for all DIOLEN® POLYESTER and TIMBRELLE® POLYAMID 6.6 yarns of TWD Fibres. The optional yarn finish is a pollution-free alternative compared to fluorine-based hydrophobisation and is compliant with the requirements of the Detox-Campaign. The hydrophobic properties of Green FC Free have been tested by various standard test methods and confirmed by independent testing institutes. Perfluorooctanoic acid (PFOA), its salts and precursors were ranked by the European Commission as being substances of very high concern. Hence, from July 2020 onwards no more PFOAs of 25ppm or higher may be placed on the market.
