Aramid fiber is an artificial (synthetic) fiber with high strength, heat resistance, strong fabric integrity even at high temperatures, high toughness, abrasion resistance, resistance to chemicals and organic solvents, and insolubilization. Simply put, aramid is a man-made fiber that has a chemical structure that gives it high heat resistance and degradation resistance. Aramid is produced by spinning solid fibers from liquid chemicals into high performance fibers for a variety of applications, including spinning into yarns used in the manufacture of protective fabrics and garments - for arc flash protection, flash fire protection, military, Fire, and so on. Aramid flame retardant fabrics have a wide range of uses and applications, including oil and gas, petrochemical, chemical, pharmaceutical and electric utilities. Nomex fiber is also used in protective clothing in the fire, racing, military, police and aerospace industries. Nomex IIIA is used for flash fire protection in the oil and gas industry and consists of 93% Nomex fiber, 5% Kevlar® and 2% antistatic fiber.
There are two main types of aramid, defined by their molecular composition:
Meta-aramid is most commonly used in textiles such as protective clothing. One of the most famous aramids fabric is DuPont's Nomex®. This inherently flame retardant fabric can be used for arc flash and/or flash fire protection. Para-aramids fabric are even stronger and are more commonly used in applications that require extremely high tensile strength. The most famous para-aramids fabric include DuPont's Kevlar®. Kevlar® may be known for its use in bulletproof vests. Nomex is an inherent FR fiber that does not burn or melt and drip, its protective properties are permanent; they cannot be washed away or worn. When exposed to extreme temperatures during arc flash or flash fire, Nomex swells and forms a char, providing the wearer with critical protection and additional effective seconds. The protective char remains soft until it cools. Known for its long life and decades of global use. Made of meta-aramid yarn.
