Polymers are obtained when many small units are joined together chemically. On burning it turns into ash. Synthetic fibers are immune to these pests and do not suffer damage from sun, water or oil exposure. Natural fabrics, like merino wool, cotton, cashmere, and silk, are made of fibers that are produced by animals and plants. One is synthetic fiber and another is regenerated fiber. These blends are called mixed fibres. All synthetic fibers are filament fibers with a rod like structure, long, circular in shape when cut in a cross section. Synthetic fibres are the man-made polymers designed to make a fabric. Natural fibers are fibers that are made out of natural materials that come from plants, animals, or minerals. In general, the properties of synthetic fibres can be engineered to suit different end-uses when the fibres are manufactured. Polyamides and polyesters are two groups of synthetic fibres with high strength, not easily stretched and used as textile.
