Kerala produces a great variety of products made out of coir as a raw material. The commercial production of coir in Kerala dates back to the ninetieth century and has become the largest cottage industry in the state, employing millions. The beginning of coir spinning wheels during the mid nineties, facilitated in increasing the production and to obtain the required yarn strength for the manufacturing of matting. The coir fibre is elastic and flexible to twist without breaking and it holds a curl as though permanently waved. The coconut contains three layers– the outer layer which is smooth and greenish is called the Exocarp; the inner layer which is the fibrous husk is called Mesocarp and the innermost layer surrounded by the hard woody layer is called the Endocarp. The coir fibre is water-proof and resists damage against salt water. The sea water and fresh water is used in the production of white coir.
