Coconut Fibers (Coir) are derived from the husk of the coconut. The coconut tree grows in hot and wet tropical climates a they need year round warmth and moisture. The fibers can be used to make brushes, spun into yarns for marine cordage and fishnets. It can also be used as a cushion for shoes, mattresses, upholstery and as and packaging for eggs, perfume and luxury gifts.

Harvesting

The highest producers of coconuts in 2019 were Indonesia, Philippines, India, Sri Lanka, Brazil and Mexico. Coir can be sourced as agricultural waste from the coconut oil industry.

Forming

The fibers are washed, dried, curled by a spinning process and fixed with steam. The fibers can be bound together by needling. Fibers can be combined with latex rubber to form sheets of various thickness that can be pressed into 3D forms or die-cut into shapes. Used as a natural fiber reinforcement for concrete, insulation and doormats.

Sustainability

Sustainable and compostable. Renewable but coconut trees only produce 50 – 100 fruits per year. Environmentally friendlier alternative to peat moss in gardening. It is used as a growing medium for hydroponic gardening and can help retain moisture and aerate the soil.

Physical Properties

The processed fibers are 4 – 12 inches, lightweight, brittle, strong and elastic with a tendency to curl. The coarse, reddish brown fiber is composed of smaller threads that are cellulose and lignin (a woody plant substance). Hand processing yields a superior fiber, resistant to abrasion and easily dyed.

May be covered with latex to give it elasticity.

Good for sound insulation.

Waterproof - The fibers swell in water and are used in boats for plugging spaces between planks.
