*CORDURA*
Nylon is a thermoplastic silky material, first used commercially in a nylon-bristled toothbrush (1938), followed more famously by women's “nylons” stockings (1940). It is made of repeating units linked by peptide bonds (another name for amide bonds) and is frequently referred to as polyamide (PA).
Nylon was the first commercially successful polymer and the first synthetic fiber to be made entirely from coal, water and air. These are formed into monomers of intermediate molecular weight, which are then reacted to form long polymer chains. It was intended to be a synthetic replacement for silk and substituted for it in parachutes and also making things like ropes, flak vests, vehicle tires, combat uniforms and many other military uses after the United States entered World War II in 1941, making stockings hard to find until the war's end.
Nylon fibers are now used in fabrics, bridal veils, carpets, guitar strings and ropes, and solid nylon is used for mechanical parts, drumstick tips and as an engineering material. Engineering grade Nylon is processed by extrusion, casting & injection molding. Type 6/6 Nylon 101 is the most common commercial grade of Nylon, and Nylon 6 is the most common commercial grade of cast Nylon.
Cordura is the registered name of a certified nylon fabric from INVISTA. It is used in a wide range of products from luggage and backpacks to boots, military apparel (such as tactical blade sheaths, ammunition pouches, etc.), and performance apparel.It is designed to be long lasting and resistant to abrasions, tears and scuffs.
Prior to 1966, the name Cordura referred to a strengthened version of rayon, which was used in tires and other uses. When nylon was developed and proved superior, the Cordura brand was transferred to refer to the nylon product instead.
