Natural fabrics, like merino wool, cotton, cashmere, and silk, are made of fibers that are produced by animals and plants. Synthetic fabrics, like polyester, nylon and acrylic, are "man-made" fibers that are created in laboratories.
There are two types of fibres – One is natural fibres which are obtained from natural sources e.g. Cotton, silk, wool and other is synthetic fibres which are man-made for example – rayon, nylon, acrylic etc. II. A Synthetic Fibre is a chain of small units of chemical substance joined together.
Explanation:
Natural fibres:
Fibres produced by plants or animals are called natural fibres. Best examples of plant fibres are: linen and cotton. Examples of animal fibres are: wool and silk. They have natural color. Incase coloring is required then dying is very easy. Usually natural fabrics are comfortable to wear. It is environmental friendly. On burning it turns into ash. Limited use of these fibres when compared to synthetic fibres.
Synthetic fibres:
Man made fibres created in laboratories are called synthetic fibres. Examples of synthetic fibres are acrylic, nylon and polyester. Colors can be added as per required. Coloring is difficult. Theses fabrics are not comfortable to wear when compared to natural fibres. It is not environmental friendly because some fibres like polypropylene is harmful. On burning it melts and gives out chemical smell. These fibres are more durable than natural fibres.
