Nylon 66 is a type of polyamide or nylon. There are many kinds of nylon.
The two most common types in the textile and plastics industries are nylon 6 and nylon 66. Nylon 66 is made of two monomers, each containing six carbon atoms, namely hexamethylenediamine and adipic acid, hence the name of nylon 66.
Nylon 66 has excellent mechanical properties, high tensile strength and high tearing strength, suitable for making industrial fabrics.
Nylon 66 also has great frictional resistance and good flexibility which makes it a suitable fabric for extreme outdoor gears.
