Trevira CS (Polyester – flame retardant)
Trevira CS is a brand name for polyester with flame retardant qualities. Fabric produced with Polyester Trevira CS is permanently flame retardant. This quality is owed to the polyester fibre. Polyester curtain fabrics are stabilised during the finishing process. Because of this, and because polyester fibre is highly waterproof, these curtain fabrics are highly washable, and have a low shrinkage rate (± 1%). Polyester curtains are not prone to sagging.
