what is natural fibre

Natural fibers are hairlike raw materials directly obtainable from animal, vegetable, or mineral sources. They can be classified into different categories based on their origin. The vegetable or cellulose-based class includes important fibers such as cotton, flax, and jute, while the animal or protein-based fibers include wool, mohair, and silk. Examples of natural fibers include cotton, flax, hemp, bamboo, sisal, and jute, which are sourced from plants, as well as wool and silk, which are obtained from animals. Natural fibers have various advantages, such as high specific stiffness and strength, biodegradability, and availability from renewable sources
