Question

What are natural fibres? Give two examples of natural fibres.​

Answer 1

$\sf \hookrightarrow \bf \underline{Natural \: Fibres :}$

• Natural Fibres are fibres that are obtained from animals, plants and mineral sources.
• Most of them are obtained from both Animals and Plants.
• Fibres that are obtained from Plants are called Plant fiber.

→ Examples of Plant Fibers : Cotton, Jute, and Linen.

• Fibres that are obtained from Animals are called Animal Fiber.

→ Examples of Animal Fibers : Wool, Silk, and Alpaca.

• Natural Fibres
• Synthetic fibres  

⇒ Synthetic fibres are also called as Man-made fibres.

Explanation:

• Natural fibers or natural fibres (see spelling differences) are fibers that are produced by geological processes, or from the bodies of plants or animals. [1] They can be used as a component of composite materials, where the orientation of fibers impacts the properties.[2] Natural fibers can also be matted into sheets to make paper or felt.[3][4]

• Natural fibers or natural fibres (see spelling differences) are fibers that are produced by geological processes, or from the bodies of plants or animals. [1] They can be used as a component of composite materials, where the orientation of fibers impacts the properties.[2] Natural fibers can also be matted into sheets to make paper or felt.[3][4]The earliest evidence of humans using fibers is the discovery of wool and dyed flax fibers found in a prehistoric cave in the Republic of Georgia that date back to 36,000 BP.[5][6] Natural fibers can be used for high-tech applications, such as composite parts for automobiles. Compared to composites reinforced with glass fibers, composites with natural fibers have advantages such as lower density, better thermal insulation, and reduced skin irritation. Further, unlike glass fibers, natural fibers can be broken down by bacteria once they are no longer in use.
