The word 'coir' has been derived from the Malayalam word 'kayar' or 'kayaru', which means the traditional entwined rope.
Uses and Applications
Coir is used in brushes, doormats, mattresses and sacking. A small amount is also made into twine. Pads of curled brown coir fibre, made by needle-felting (a machine technique that mats the fibres together) are shaped and cut to fill mattresses and for use in erosion control on river banks and hillsides. A major proportion of coir pads are sprayed with rubber latex which bonds the fibres together (rubberized coir) to be used as upholstery padding for the automobile industry. The material is also used for insulation and packaging. The major use of coir is in rope manufacture. Mats of woven coir fibre are made from the finer grades of bristle and white fibre using hand or mechanical looms. Coir is recommended as substitute for milled peat moss because it is free of bacteria and fungal spores.
Some Coir Products
Traditional uses for the resilient and durable coir fiber include rope and twine, brooms and brushes, doormats, rugs, mattresses and other upholstery, often in the form of rubberized coir pads.

Currently, the worldwide yearly manufacture of coir fiber is about 350,000 metric tons (MT). At present India and Sri Lanka jointly account for about 90% of international coir fiber production. Other main coconut growing countries, include Philippines, Thailand and Vietnam.
In the 1980s and 90s, international exports of coir fiber was cut down by approximately half, as Western customers moved to artificial foam and fibers. Since 1990, speedily rising domestic demand in India doubled promoting solely the Indian coir industry. As a final point, since 2001, a increasing Chinese demand for coir, a growing market for coir-based erosion control products, and the extension of coir pith as a peat moss alternate in horticulture has advanced global production and prices.
Traditionally, Sri Lanka has been the world’s largest exporter of various fiber grades, whereas India has largely exported value added products – yarn, mats, and rugs. Global trade volume for coir fiber, value added products – yarn, mats, rugs – and coir pith now stands at about $140 million per year with India and Sri Lanka respectively accounting for about $70 and $60 million of that amount.
