Nature Fiber - Coir 椰壳纤维




Coir is extracted from the tissues surrounding the seed of the coconut palm ( Cocos nucifera ). There are two types of coir : brown fiber, which is obtained from mature coconuts ; and white fiber, which is extracted from immature green coconuts after soaking for up to 10 months.

White coir spun into yarn is used in the manufacture of rope and fishing nets. Brown coir is used in sacking, brushes, doormats, rugs, mattresses, insulation panels and packaging. In Europe, the automobile industry upholsters cars with pads of brown coir bonded with rubber latex.

Geotextiles made from coir mesh are durable, absorb water, resist sunlight, facilitate seed germination and are 100% biodegradable.


Coir peat, a residue of milling, is gaining importance as mulch, soil treatment and a hydroponic growth medium.


Globally, about 500,000 tonnes of coir are produced annually, mainly in India and Sri Lanka, followed by Thailand, Vietnam, the Philippines, and Indonesia.
