Nylon makes a silky material which was first used in toothbrushes. It is used to make clothes. In fact, most polyamidea are most used for synthetic fibres in clothing. Nylon can also be used to make war materials, such as parachutes and ropes. Nylon was invented by Wallace Carothers at Du-Pont. Nylon is like silk in appearance.
