What is Coir?



The versatility of coconut fiber (coir fiber and extracts) has led to its wide usage in various industries. Coir fiber has established a remarkable reputation in the horticultural, agricultural and the erosion control industries.


Coir fiber is found between the husk and the outer shell of a coconut. The individual fiber cells are narrow and hollow, with thick walls made of cellulose. They are pale at first but are hardened later and yellowed as a layer of lignin is deposited on their walls. The high lignin content (46% by weight) of coco fibers makes it naturally resistant to mold and rot and requires zero chemical treatment.


There are two varieties of coir:

Brown coir is harvested from fully ripened coconuts. It is thick, strong and has high abrasion resistance. Mature brown coir fibers contain more lignin and less cellulose than fibers such as flax and cotton; this makes it stronger but less flexible.

White coir fibers are harvested from coconuts before they ripen. These fibers are white or light brown in colour and are smooth and fine. However, they are weaker than brown coir.
