LENZING™ FR is a sustainably produced inherently flame-resistant cellulosic fiber based on Lenzing’s renowned Modal fiber production process. LENZING™ FR is commonly blended with other high performance fibers to produce unique protective solutions for a variety of industrial applications. LENZING™ FR fibers typically contribute both protective qualities and enhanced comfort to these fabric blends.
LENZING™ FR blends offer unique solutions in all three areas of this application: wild land, structural fire fighting, and station wear. In structural fire fighting very low RET data of LENZING™ FR fibers (a measure of fabric breathability), scientifically recorded, shows a big improvement in reducing fatigue and heat stress, the number one killer of fire fighters in the USA. High performance LENZING™ FR fiber blends offer a solution-based complete concept for fire fighters, combining efficient flame and heat protection with improved physiological performance and enhanced comfort.
The “layers” concept includes protective wear with direct skin contact like underwear, hoods and gloves, as well as outer layers such as jackets and trousers. In turnout gear LENZING™ FR can be used in the facecloth, thermal/moisture barrier and the outer shell. Extensive tests on multi-layer garments under European standard EN469 confirm the effectiveness of LENZING™ FR blends in combining protection with comfort.
Personnel in metal smelting operations face inherently difficult conditions, including high ambient and radiant heat and metal splashes that can cause regular clothing to catch fire. Engineered blends incorporating LENZING™ FR fibers provide unique solutions for this industry against both ferrous and non-ferrous metals, in particular in the primary aluminum Industry, where it has previously been very difficult to provide workers with comfortable protection against the very aggressive mineral cryolite. Many global aluminum corporations are using LENZING™ FR blends, some for the past 20 years.
