Coconut fibre, also known as coir, is obtained from the outer shell of the unripe coconut. The cellulose content of just 44 % is rather low compared to other natural fibres. As a result, the fibres have a high proportion (approx. 45 %) of lignin, which leads to high elasticity and durability. The fibres are resistant to fungal and bacterial attack and can also withstand months of moisture without deteriorating. They are mainly used today in ropes, mats, carpets and wall coverings. The use of coconut fibres as a filler is enjoying increasing popularity. It is used here to improve the mechanical properties as well as to refine the appearance of components (e.g. injection moulded parts).
Advantages
Disadvantages
The largest production facilities for coconut fibre are found in Sri Lanka. In addition, countries such as the Philippines, Indonesia and Malaysia also play an important role. Only unripe fruits are used to produce the fibres. Here, the mesocarp is separated from the nut inside and then stored in water (this is known as ‘retting’) where the pectins present between the fibres are decomposed by microorganisms. The fibres can then be separated and sorted according to colour and fineness.
