With the aim to contribute to higher levels of safety in the clothing, furniture and transportation sectors, DOMO has developed a new flame retardant polyamide 66 fiber. NYLEO® PROTECT combines all the advantages of polyamide 66, such as mechanical properties, comfort, low specific weight and outstanding abrasion resistance, with better flame retardancy. Indeed, the limiting oxygen index (LOI) of NYLEO® PROTECT has been improved up to 28%, which is the level of typical flame retardant fibers. Thanks to its unique properties, NYLEO® PROTECT offers a wide range of actions to enhance product performance, including for the workwear segment. Our global customers rely on DOMO's performance fibers because they are particularly resistant and resilient, including for under and outer garments for firefighters, military, construction and trades functions. 


Our fiber is antimony-, halogen- and bromide-free and is OEKOTEX® certified. NYLEO® PROTECT is available in​ a broad range of solutions, including staple fibers (from 1 to 30 Dtex​; cut length from 38 to 155 mm), tow for flock or short cut fibers (from 1 to 30 Dtex​) and crimped tow (from 2.2 to 6.7 Dtex​). NYLEO® PROTECT has an outstanding density of 1.14 g/cm3. 

Improved Limited Oxygen Index (LOI) performance

NYLEO® PROTECT also features improved LOI up to 28, which is the level of typical flame retardant fibers.

Exceptional mechanical performance and abrasion resistance

In comparison to PET FR, Modacrylic, Viscose FR, Meta-aramid, cotton FR or wool, NYLEO® PROTECT polyamide 66 displays a higher tenacity, enhanced mechanical properties and the highest abrasion resistance.

Abrasion resistance
