This small but decisive difference is due to the chemical structure of the polyester fibre. The flame retardant properties are firmly anchored in the fibre in the form of a comonomer – an organophosphorous compound. As a result, they remain unaffected by external influences.
Comfort and safety, the two most important requirements in home textiles, were first successfully combined in 1980 with the creation of flame retardant Trevira fibres and yarns. Textiles made from these fibres and yarns carry the trademark Trevira CS and are permanently flame retardant. Unlike fabrics that receive a surface treatment at a later stage, Trevira CS textiles offer long-term safety and security.
