FORMATION OF COIR
 


Woven magnificence is what you see in a coir product. The efforts behind manufacturing the raw materials are huge and involve several processes. The starting point of the industry is the process of de-husking after harvesting of the mature coconut crop.

 


Coir fibre is extracted from the husks surrounding the coconut. In most areas coir is a by-product of copra production, and the husks are left on the fields as mulch or used as fertiliser due to high potash content. For production of light coloured fibre of spinnable quality, green husk of 10 to 12 months old coconuts is ideally suitable.
India and Sri Lanka are the main areas where the fibre from the husk (termed 'coir') is extracted by traditional methods for the commercial production of a variety of products (brushes and brooms, ropes and yarns for nets and bags and mats and padding for mattresses)
 

 

 


However, world wide, only a small part of the fibre available are currently used for these purposes. The average fibre yield is dependent on geographical area and the variety of the coconut tree.
In the south of India and Sri Lanka, where the best quality fibre is produced, the average yield is 80-90 g fibre per husk, while the Caribbean husks which are relatively thick may yield up to 150 g of fibre. The husks are composed of 70 percent pith and 30 percent fibre on a dry weight basis. The ratio of yield of long, medium and short fibre is on average 40:40:20, respectively.
