DURAK Durafix CFR are 100% continuous polyester fibre threads to which flame protective solutions are added. This chemical flame retardant finishing method covers the surface of the threads according to international norms and quality standards. Even after 20 washes its properties are kept according to NFPA 701. They melt and self- extinguish once removed from the flame. Even at very high speeds excellent seams are achieved. DURAK Durafix CFR threads are suitable for many sectors through high strength properties, many colours and extensive ticket range.
