Cordura

Cordura is a brand of synthetic fiber-based fabrics used in products such as luggage, backpacks, trousers, military wear, and performance apparel.

du Pont de Nemours and Company (DuPont) in 1929; it is currently owned by Invista, a subsidiary of Koch Industries.

[2] DuPont introduced Cordura as a type of rayon,[3][4] a semi-synthetic fiber made from natural sources of regenerated cellulose.

“DuPont scientists were working to improve on the properties of rayon…when, in 1928, a rubber company asked for a rayon yarn that would be stronger than cotton for tire cords.

In addition, a textile finish was developed that combined just the right amount of plasticizing action and lubricating power, allowing the filaments to twist evenly in forming the cord.

Out of the cooperation among scientists—ranging from studies of cellulose as a high polymer to design of enormous plants—came a new product, “Cordura” high-tenacity rayon, as strong as mild steel yet able to stand up under repeated flexing.” Tires made with it are less bulky and cooler running, yet give greater mileage under adverse operating conditions.
