The work coir is derived from malayalam kayary-cord. It is a coarse fibre extracted from the fibrous outer shell of a coconut.

 

Structure

 

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 ( a chemical compound that is an integral part of the cell walls of some cells, example tracheids, xylary fibres and sclereids of plants) is deposited on their walls. Mature brown coir fibres contain more lignin and less cellulose than fibres such as flax and cotton and so are stronger but less flexible. They are made up of small threads, each about 1 mm and 10 to 20 mocrometres in diameter. White fibre is smoother and finer, but also weaker. The coir fibre is relatively water- proff and is one of the few natural fibres resistant to damage by salt water.

 

Processing:

Green coconuts, harvested after about six to twelve months on the plant, contain pliable white fibres. Brown fibre is obtained by harvesting fully mature coconuts when the nutririous layer surrounding the seed is ready to be processed into copra and desiccated coconut. The fibrous layer of the fruit is then sepatated from the hard shell (manually) by driving the fruit down onto a spike to split it (De-husking). Machines are now available which crush the whole fruit to give the loose fibres.
