ABOUT COIR
 


COIR is a versatile natural fibre extracted from mesocarp tissue, or husk of the coconut fruit, the nut of 'Cocos Nicifera' . The husk contains 20% to 30% fibre of varying length. After grinding the husk, the long fibres are removed and used for various industrial purposes, such as rope and mat making.

The remaining material, composed of short and medium-length fibres as well as pith tissue, is commonly referred to as waste-grade coir. The waste grade coir may be screened to remove part or all of the fibre, and the remaining product is referred to as coir pith.

 

The history explains different stories on the birth of the golden fibre. Ropes and cordage, made out of coconut fibre have been in use from ancient times. Indian navigators, who sailed the seas to Malaya, Java, China and to the Gulf of Arabia centuries ago, had been using coir as their ship's cables. Arab writers of the 11th century AD referred to the extensive use of coir as ship's cables, fenders and for rigging
Facts record that there was coir industry in U.K. before the 2nd half of the 19th century. During the year 1840, Captain Widely, in co-operation with Captain Logan and Mr. Thomas Treloar founded the well-known carpet firms of Treloar and Sons in Ludgate Hill, England for the manufacture of coir into various fabrics suitable for floor coverings.
The coir manufacturing industry producing coir mats, mattings and other floor coverings, was started in India on a factory basis, over a hundred years ago when the first factory was set up in Alleppey in 1859 by the Late Mr. James Darragh, an adventurous Irish born American national. Enterprising Indians followed the trail blazed by this foreigner.
