Synthetic fibre is a manufactured fibre made in industries using chemicals. It comprises small monomers units bound concurrently to form a long-chain polymer. Nylon, acrylic, rayon, and plastic are some instances of synthetic fibres.
Plastic is also a manufactured fibre like synthetic fibre. It may be linear or cross-linked. The arrangement of units is not identical in all kinds of plastics.
