Coir

Coir, seed-hair fibre obtained from the outer shell, or husk, of the coconut. The coarse, stiff, reddish-brown fibre is made up of smaller threads, each about 0.03 to 0.1 cm (0.01 to 0.04 inch) long and 12 to 24 microns (a micron is about 0.00004 inch) in diameter, composed of lignin, a woody plant substance, and cellulose. India and Sri Lanka are top coir producers.
