pls can someone tell me were i can get info on natural fibre extraction

Natural fibres Potentials Reinforcement For polymers (Synthetic or Natural)

Coconut fibre known as coir is a nature fibre extracted from the husk of coconut and used in products such as floor mats, door mats, brushes, mattresses etc. Coir is the fibrous material found between the hard, internal shell and the outer coat of a coconut. The individual fibre cells are narrow and hollow, with thick walls made of cellulose. They are pale when immature, but later become hardened and yellowed as a layer of lignin is deposited on their walls. Each cell is about 1mm long and 10 to 20µm in diameter.

The two varieties of coir are brown and white. Brown coir harvested from fully ripened coconuts is thick, strong and has high abrasion resistance. Mature brown coir fibres contain more lignin and less cellulose than fibres such as flax and cotton, so are stronger but less flexible. White coir fibres harvested from coconuts before they are ripe are white or light brown in color and are smoother and finer, but also weaker, coconut coir, either brown or white is high in sodium and potassium content (Hunt, Robert, Ricciard, Zac, 2011).

Fillers as composites acts as modification to various properties of polymers. These fillers are much stiffer and stronger than the polymer and usually increases its modulus and strength and also subsequently affects many other mechanical properties of polymers which includes thermal expansion, transparency thermal stability and so on. They can also extend their properties to fine retardants, electrical and magnetic property modifiers, surface property modifiers and processing aids.

Coir which is thick and coarse, resistant to abrasion and salt water has been strongly proven by many studies to exhibit certain of these properties of filler as it has played a very significant and important role as composites in polymers and therefore, has been considered as a traditional filler. These studies, thus, has being carried out in different parts of the world with coir sample collected from different locations band different results has being taken into account bout to the best of my knowledge, none of these researches has bei
