Coconut Coir also known as coconut fiber, a natural fiber extracted from the husk of coconut. Coconut fiber is used to manufacture products such as floor mats, doormats, brushes and mattresses. Coir is the fibrous material found between the hard, internal shell and the outer coat of a coconut. Other uses of brown coconut fiber (made from ripe coconut) are in upholstery padding, sacking and horticulture. White coir, harvested from unripe coconuts, is used for making finer brushes, string, rope and fishing nets.
