A very strong and resilient, waterproof, extruded fibre with a silky, shiny finish chemically produced from petroleum, and introduced by the American chemical company DuPont in 1939. Nylon and its derivatives have virtually replaced natural fibres in some cases, as with ropes and outdoor furniture, even quite convincingly mimicking cane and bamboo, which is jolly useful as it not only withstands all weathers and temperatures but resists dirt and stains as well. .
