Coir is a natural fiber derived from the outer husk of coconut and
used in items such as floor mats, doormats, brushes and mattresses, or coconut fibre.
Coir is the fibrous substance that is present
between a coconut's rough, internal shell and outer coat.
In upholstery lining, sacking and horticulture, other uses
of brown coir (made from ripe coconut) are
For making finer brushes, string, rope and fishing nets, white
coir, harvested from unripe coconuts, is used.
Between the rough, internal shell and the outer
coat of a coconut, coir fibres are contained.
The individual fibre cells are small and
hollow, with thick walls made of cellulose.
When immature, they are pale, but are later hardened and
yellowed as a coating of lignin is formed on their walls.
