Coir....is a natural fibre extracted from the husk of coconut[1]and used in products such as floor mats, doormats, brushes and mattresses. Coir is the fibrous material found between the hard, internal shell and the outer coat of a coconut. Other uses of brown coir (made from ripe coconut) are in upholstery padding, sacking and horticulture. White coir, harvested from unripe coconuts, is used for making finer brushes, string, rope and fishing nets.
Silk Cotton.....Some species are harvested for their wood, which is rather soft and can be easily carved into dugout canoes and other useful products. Balsa wood is an extremely light yet strong wood that is obtained from the fast-growing balsa tree (Ochroma pyramidale). This species is native to tropical forests of Central and northern South America, but most balsa wood is now harvested from plantations. Balsa wood is widely used to make architectural and other models, and to manufacture airplanes, flotation devices, and bottle corks.
Balsa wood was also used to construct the Kon Tiki, a simply-built raft used by Thor Heyerdahl, an anthropologist

Coir fibres are 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
The two varieties of coir are brown and white. Brown coir harvested from fully ripened coconuts is thick, strong and has high abrasion resistance. It is typically used in mats, brushes and sacking. 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. They are generally spun to make yarn used in mats or rope.
The coir fibre is relatively waterproof, and is one of the few natural fibres resistant to damage by saltwater. Fresh water is used to process brown coir, while seawater and fresh water are both used in the production of white coir.
