Define: Kevlar® & Nomex® Fiber

These two brands are belong to DuPontTM. They are most used ARAMID material, which Kevlar® is para-aramid and always has a natural color of yellow, on the other hand, Nomex® is meta-aramid and has a natural color of white.

Kevlar® has successfully emerged out as one of the ultra high-performance fiber since it’s been first introduced by Stephanie Kwolek on 1971, and was registered by DuPont as a famous para-aramid material commercial brand. This magic fiber has various amazing features: long-term working in high-temperature environment, high tensile load, low elongation.

Advanced Properties of Kevlar® | Para-Aramid fiber

High strength to weight ratio
Low elongation to break
Low thermal shrinkage
Good heat & flame resistance
Self-extinguishing flame retardant properties
Good chemical resistance
Excellent bulletproof/ballistic properties
High cut resistance (not so easy to cut off than normal fibers)
UV resistance good (ONLY on black and other non-natural color fiber)
UV resistance poor (natural, and please notice this is the MAIN WEAKNESS of aramid fiber)

Common Types & Deniers
T-29: Standard Modulus
T-49: High Modulus
AP: 15% higher tenacity than T-29

Comparision of Materials

For complicated working conditions, ordinary materials are more and more replaced by aramid, UHMWPE, PBO fibers. With these advanced fibers, we managed to develop a series of textile which includes sewing thread, string, rope, straps, webbing, and fabric.
