Nylon is a man made replacement material for silk. Like silk it is smooth, light yet strong and durable. Carbon is an important element of Nylon. There are other man made materials like Nylon. Plastics are another example. These materials are called Polymers. Polymers have their molecular structure arranged into long connecting chains like a long train with attached trailers. This chaining gives them their strength.
Nylon is used for stockings, ropes, and nets.
