Coir fibre is obtained from husk of coconut & composed of highly lignified form of cellulose. All coir fibre falls into two distinctly different categories viz. white coir and brown coir. The differences between two categories are due to the conditions of husk used, the method of extraction, the physical properties as well as in the uses. This review article discusses about the physical & chemical properties of coir fibre and the current status of coir industry in India. The processing and various applications of coir fibres are brought out.

Coir fibre is obtained from the outer layer of the fruit of coconut tree (Cocos Nucifera L). This outer layer is called the coconut husk and this husk (exocarp) of the coconut consists of a smooth waterproof outer skin (epicarp) and fibrous zone (mesocarp).
