Coir is a versatile natural fibre extracted from mesocarp tissue, or husk of the coconut fruit. The husk contains 20% to 30% fibre of varying length. After thrashing the husk, the long fibres are removed and used for various industrial purposes such as rope and mat making. Industries based on coir have developed in many coconut producing countries especially India, Tanzania, Kenya, Bangladesh, Burma, Thailand, Sri Lanka, Nigeria and Ghana.
Uses and Common Types of Coir Fibres:
Brown coir is used in floor mats, door mats, brushes, mattresses, floor tiles and sacking.
White coir is mainly used in rope manufacturing. It is also used in the fabrication of fishing nets.
Coir fibre is high in sodium and potassium, therefore it is used as a growth medium for plants and herbs.
Steps Involved in the Manufacturing of Coir Fibres:
Deterioration: Coir has been found to be remarkably resistant to both fungal and bacterial decomposition.
Spinning: It is produced either by wheel spinning or hand spinning or mechanized spinning.
Weaving: Coir yarn is treated with dilute solution of sulphuric acid, which improves its color and gives a certain amount of brightness for the production of various products.
Dyeing and Printing: Color and design play an important part in the marketing of coir products.
