Nylon- Nylon was first commercially synthesized fibre.
Synthetic fibres and plastics, similar to natural fibres are made up of very large units. The larger units are called polymers. These are made up by combining many similar or dissimilar small units. The small units are called monomers. Natural fibres are obtained from plant and animal sources, synthetic fibres are obtained by chemical processing of petrochemicals.
Fibres and Fabrics The clothes are made of fabrics. Fabrics are made from fibres obtained from natural or artificial sources. Types of Fibres: 1.
