____________________________

➙ There are generally two types of fibres, natural and synthetic.

➙ Fibre's which are naturally occurring and are obtained from plants and animals are known as natural fibres. For example cotton, wool, jute, silk, rubber etc.

➙ Fibre's that are artificial or man made are known as synthetic fibres. For example nylon, terrylene, acrylic, polyester, rayon etc.

➙ Natural fibres are costly, not much available but are not harmful to us.

➙ Synthetic fibres are low cost, readily available, can be easily washed but they are harmful to us as they are hydrophobic in nature and in case of heat, they can even cause heavy burns.
