TREVIRA CS : Permanently flame retardant textiles. The abbreviation CS stands for comfort and safety.
Textiles made from these fibres and yarns bear the trademark Trevira CS and are permanently flame retardant, unlike fabrics that receive a surface treatment at the finishing stages of production.
This small but decisive difference results from the chemical structure of the polyester fibre. In the shape of a comonomer – a phosphor-organic compound, where the flame retardant properties are firmly anchored in the fibre. It is not possible for external influences to affect them.
Thus it is possible to wash these curtains, sheers, drapery without loosing the inherent flame retardant properties.
