Nylon is a very strong fibre that is why nylon is used for making parachutes, rock climbing ropes, fishing nets seat belts etc. A nylon thread is elastic and light but actually stronger than a steel wire. https://www.tiwariacademy.com/ncert-solutions/class-8/science/chapter-3/

Some fibres which are not natural (man-made fibres) called synthetic because they are made by chemical processing of petrochemicals. The synthetic fibres are made up of very large units called polymers. Some of the synthetic fibres are rayon, nylon and acrylon. https://www.tiwariacademy.com/ncert-soRead more
