Koyr (from malayal. കയർ kayar - rope) - fiber from the inter- fruit of coconut palm nuts. These are lignified vascular bundles 15–33 cm long and 0.05–0.3 mm thick. The walls of the fibers are made up of cellulose . In their immature form, they are white and soft, but as lignin is deposited in them, they become harder and acquire a reddish-brown color. Flexible white fiber is obtained from unripe fruits, brown - from fully ripened.
Collected coconuts are soaked in sea or just running water (up to 10 months), then the fibers are separated (usually by hand), combed and dried. The longest (25.4-30.5 cm) and medium (20.3-25.4 cm) fibers are used to make coir yarn, which are used to make mats, mats, fishing ropes and ropes that do not get wet or drown in water, and fishing network. The coarse lignified fiber of ripe nuts goes to the manufacture of brush products, the short and tangled fiber goes to the packing of mattresses and pillows. Due to its high lignin content, coconut fiber is very flexible, strong and resistant to decay. Products made of coir, in particular nautical ropes, are exceptionally resistant to salt water.
