a fiber from the mesocarp of nuts of the coconut palm. Coir consists of lignified, vascular bundles of a red-brown color. Length, 15–33 cm; thickness, 0.05–0.3 mm. The best coir is obtained from underripe coconuts; these are soaked in seawater, and the fibers are then combed. The longest (25.4–30.5 cm) and medium-length (20.3–25.4 cm) fibers go to manufacture coir threads, which are used to make doormats, floor mats, nonwettable and nonsinking strings and ropes, and fishnets. The coarse, woody fiber of mature coconuts is used to manufacture brush products; short and tangled fiber is used to stuff mattresses and pillows. Coir is produced chiefly in India and Sri Lanka (Ceylon).
