Project Description

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 KM2: Optimized ballistic resistance Deniers: 200, 380, 400, 750, 800, 1000, 1420, 2160, 2250, 2840, 3000, 7100

Advanced Properties of Nomex® | Meta-Aramid fiber

Lower elongation to break the 4th level of dye colorfastness, dyeable Low thermal shrinkage Excellent heat & flame resistance Self-extinguishing flame retardant properties Soft-hand yields good textile properties High chemical resistance

Common Types & Deniers T-430: Filament Yarn Deniers: 200, 1200, 1600, 2400

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. Here’s the table of specifications of various materials:
