Cordura, FR cotton, and Nomex are all types of fabric, each with distinct properties that make them suitable for specific uses:

1. Cordura Fabric: Cordura is a type of fabric developed by DuPont that is known for its durability and resistance to abrasions, tears, and scuffs. It is often used in performance gear, luggage, backpacks, and military and outdoor apparel. Cordura fabrics are often made from nylon.

2. FR (Fire Retarded) Cotton: FR Cotton is cotton that has been treated with a flame retardant substance to make it resistant to ignition or burning. This type of fabric is typically used in industries where workers are exposed to potential fire hazards, such as welding, electrical work, oil and gas industry, and firefighting. FR cotton provides the comfort of cotton while also offering protection against potential fire hazards.

3. Nomex: Nomex, another product developed by DuPont, is an inherently flame-resistant material used to make fabrics, fibers, and other materials. It doesn’t melt, drip, or support combustion in air, and it also provides excellent heat and flame resistance. Nomex is commonly used in applications such as firefighter gear, racing suits, and other protective apparel, where high heat or fire is a risk.
