German Government funded DTNW project will develop non-halogenated reactive fabric dyes with FR properties. Every textile finishing process involves washing and drying of textiles, which requires water and energy. By combining into one the two processes of dyeing and flame retardants finishing, both resources can be saved. DTNW (Deutsches Textilforschungszentrum Nord-West gGmbH) is developing new one-pot synthesis flame retardant dye products, which ensure both dyeing and fire protection of fabrics such as cotton or polyesters. The chemical immobilisation of the PIN FR-dyes onto the surface of finished textiles is expected to ensure very low environmental exposure and high durability.
The project is financed by AiF (IGF No. 22599 N) (German Federation of Industrial Research Associations) of the German government https://www.dtnw.de/en/projekt/flammschutz-farbstoffe/
