1. The fibres obtained from plants and animals are called natural fibres. Examples of natural  fibres include cotton, jute, wool, and silk. 

2. Man-made fibres are known as synthetic fibres. They are made by carrying out reactions between various chemicals. For example: Rayon, nylon, acrylic, and polyester.

3. When the jute plant is in the flowering stage, it is harvested. After harvesting, it is kept submerged in water for a few days. During this period, the stem of the plant rots and the fibres (present in the stem) remain. The process by which fibres are obtained from the stem of the plant is known as retting. These fibres can then be separated from the non-fibrous matter by hand. This process is known as stripping. After the fibres are separated, they can be spun into yarns and fabrics can be made from these yarns.
