COIR
FIBRE
A Natural & Water Resistant Fibre
Coir, also known as coconut fibre, is a natural fibre that’s extracted from or that is between the hard, internal shell and husk of coconuts. Coir fibres are one of the most lignin-rich natural fibres.
We supply brown coir. Brown coir is made from ripe coconuts and is used to manufacture upholstery padding, floor and doormats, brushes, mattresses, and horticulture.
Coir is widely used because of its highly water resistant properties against water and seawater. It’s the thickest and most resistant of all commercial natural fibres, and its low composition rate is the key advantage of its durability. Coir also features excellent thermal and sound insulation.
Quality matters, so at Goonvean Fibres, we’ve added further value to our coir fibres, including purchasing large volumes to maximise production and demand, greater range, and traceability.
Available in a range of sizes.
Standard Fibre Details
Our coir natural fibres are often used as a base material in filtration systems. They are also very efficient at absorbing organic chemicals, pesticides, herbicides, disinfection by-products, and improving the appearance and taste of drinking water.
Our coir Flocks can filter out common particulates and impurities and are highly resistant to seawater damage.
Other characteristics include resistance against fungi and rot, insulation against temperature and sound, static-free, and not easily combustible.
Technical Fibre Details
The individual cells of coir fibres are narrow and hollow, with thick walls that are made of cellulose. Mature brown coir fibres are stronger and more flexible as they contain more lignin and less cellulose.
The husk (exocarp) of coconuts consists of a smooth water resistant outer layer (epicarp) and fibrous zone (mesocarp).
