What is Nylon and Its Uses?

Nylon, or polyamide (PA), a synthetic polymer, is a high-molecular-weight polymer that contains amide groups (-CONH-) that add tensile strength, ductility, impact resistance, and fatigue strength. It was invented in 1935 and has found many applications in textiles, industrial products, automotive parts, and medical devices. Common examples are Nylon 6 produced by caprolactam ring-opening polymerization and Nylon 6,6 produced by condensation of hexamethylene diamine and adipic acid. It's used in textiles and parachutes as well as in machinery and electronics for its sturdiness and flexibility. But the environmental footprint of nylon production (water contamination and greenhouse gas emissions) has boosted demand for bio-based and recycled fibres.
