Synthetic fibres are man-made fibres which are produced from chemical substances.Some of the synthetic fibres are nylon, rayon, polyester, acrylic etc.Synthetic fabrics are often non-biodegradable, which means that when discarded, they do not break down in soil, and the chemicals used in their manufacture can leach out into the environment.
