Nylon was invented in the early 1930s by an American chemist, Julian Hill. Other scientists worked with his invention and finally on 27 October 1938, nylon was introduced to the world. It was cheap and strong and immediately became successful, especially in the making of ladies’ stockings.
During the Second World War, the best present for many women was a pair of nylon stockings, but more importantly, it was used to make parachutes and tyres. Today, nylon is found in many things: carpets, ropes, seat belts, furniture, computers, and even spare parts of human body. It has played an important part in our lives for over 50 years. Next year, about 36 million tons of it will be manufactured.
