Known for its inherent flame resistance, Nomex® has been the fabric of choice for protective apparel for over forty years.Nomex® is a meta-aramid fiber developed in 1961 by DuPont and first marketed in 1967. Nomex® has outstanding strength and abrasion resistance, so hoods manufactured from the fiber have exceptional wear life making them cost effective in the long run.
Recommended for STRUCTURAL FIRE FIGHTING as well as other industries which require protection from flash fire, radiant heat, electric arc or cold weather.
Other properties of Nomex® include:
- Inherently flame resistant
- Exceptional wear life
- Superb flash fire protection
- Excellent chemical resistance
- Easy Care – can be laundered using normal home and commercial laundering and dry cleaning techniques
- Mid-weight (7oz. / sq. yd.)
- Natural off-white color
- Less comfort than other hood fibers or fiber blends due to low moisture absorbency of 4.5%
- Meets CAL-OSHA Requirements
- Passes Fed. Test 191, Method 5903.2: CAL OSHA Sections 3406(d)
- Complies with OSHA Rule 29 CFR Part 1910, 269
- Outer shell and lining are 100% Nomex®/Meta-Aramid - approx. 7 oz sq yd.
- 1 x 1 rib knit fabric - knit to allow approx. 130% stretch for maximum stretch and recovery.
- Calendared to minimize laundry shrinkage.
- All stitching conforms to federal Standard 751 Specifications (FED-STD-751).
