DuPont and Lion have collaborated on a new gear that protects personnel using advanced blends of DuPont Kevlar filament, Nomex and Kevlar staple. Family owned Lion is the first company to adopt new Kevlar products in blends with Nomex to provide maximum protection in its new link of gear, dubbed Janesville V-Force, the companies announced. DuPont and Lion collaborate with fire departments around the world to test new fiber technologies and thermal protection within firefighter gear.

Lion’s Janesville V-Force garments with new Kevlar filament-based outer shells and thermal liners offer comfort and strength, using Kevlar and Nomex for added comfort, mobility and durability, the company said. Kevlar and Nomex are critical materials in three key layers: a tough outer shell with cut- and flame-resistance; a moisture barrier that prevents penetration of liquid and blood-borne pathogens; and a thermal liner that provides efficient thermal insulation while not restricting user mobility.

DuPont Nomex can withstand temperatures up to 700°F (370°C). Nomex and Kevlar are inherently fire-resistant and do not need to be treated. Tested through DuPont’s rigorous Thermo-Man unit, they are both self-extinguishing and durable, according to the company.
