COIR, the outer covering of the husk of the coconut; an exceedingly strong fibrous material which has many uses in industry, notably in the manufacture of coarse mats and brushes. The name is from the Malay Kayar, cord, Kayaru, to be twisted. Very large quantities of coir are exported from the Pacific, and there is a considerable market in England, the imports and re exports reaching big figures. In 1926 the imports into the United Kingdom of coir yarn amounted to 425,881 tons, besides a con siderable quantity, not separately stated, of coir fibre.
