Natural and Synthetic Fibres| Short Notes, Usage, Types, Important Facts

Natural Fiber:

Natural fibers are derived from plants, animals, or minerals. 

Example of Natural fibers:

  • Plant Fibers( Cotton, Jute, Flax, and Hemp)
  • Animal Fibers ( Wool and Silk)

Cotton Fiber:

Cotton is a natural polymer that is made up of Cellulose. 

It is made up of a large number of Glucose (Carbohydrates). 

Cotton fibers are obtained from seed coats. 

Wool Fibers:

Wool polymer comprises twenty amino acids, also known as Keratin Proteins( Nitrogen compounds). 

Wool fibers are obtained from hair. Pashmita wool ( Kashmir Goat) and Angara Wool ( Rabbit) are the best quality wool sources. 

Silk Fibers:

Silk polymer is comprised of sixteen different amino acids which are also known as Fibroin Protein( Nitrogen compounds). 

The cultivation of silkworms to produce silk is known as Sericulture. 

Silk is obtained from Cocoon ( Larva).

Synthetic Fibers:

Synthetic Fibers are man-made materials created through chemical processes. Examples of Synthetic fibers are Rayon, Nylon, Polyester, Acrylic, and Kevlar. 


Reyon is the first synthetic fiber.

It is also called Artificial Silk.

Reyon is obtained by chemical treatment of wood pulp, which contains Cellulose. That is why it is also known as semi-synthetic fiber. 


Nylon is the strongest fiber, which is why it is used for making conveyors and seat belts, parachutes, airbags, nets, ropes, thread, and tents.

It is also known as Polyamide.

It is the first fully synthetic fiber. 


Acrylic is used to substitute for wool.


Kevlar is a type of aramid fiber, it is extremely strong and lightweight. 

Kevlar polymer is used in the manufacturing of bulletproof jackets.
