If you've shopped for a doormat, a coconut-fiber hanging basket liner, or an erosion-control mat, you've already handled coir — even if you didn't know the name. It's one of the oldest commercially traded natural fibers in the world, and it shows up constantly in the same aisles and catalogs as banana fiber, jute and sisal. This guide covers what coir actually is, how it's made, what it's good (and not good) at, and how it stacks up against the pseudostem fiber we work with every day.

Coir comes from the outer husk of the coconut — the fibrous layer between the hard shell and the outer skin, not the coconut's flesh or shell itself. It's a fruit fiber, in the same broad plant-fiber family as banana (a pseudostem fiber) and jute (a bast fiber), but extracted from a completely different part of a completely different plant.

There are two commercial grades. Brown coir comes from fully ripe coconuts. It's thick, stiff and highly abrasion-resistant, which is why it ends up in mats, brushes and sacking. White coir comes from unripe coconuts, is smoother and finer, and is mainly spun into yarn for rope and lighter matting — though it's also the weaker of the two grades.

Traditional coir extraction relies on retting: husks are submerged in a river, pond or water-filled pit for up to several months. Microorganisms break down the pulpy tissue surrounding the fibers, loosening them so they can be beaten out by hand, washed and dried. It's a slow, water-intensive process, and the wastewater from large-scale retting has been a documented pollution concern in major coir-producing regions — which is part of why newer, enzyme-based extraction methods that use far less water have been developed and adopted in parts of India since the late 2000s.

Hard, coarse natural fibers like coir are used across household, agricultural and industrial applications.

• Floor and door mats, brushes and bristles — brown coir's abrasion resistance makes it the default choice.
• Rubberized coir padding — used in mattresses, upholstery and some vehicle interiors.
• Rope, twine and fishing nets — mainly white coir, where saltwater resistance and buoyancy matter.
• Erosion-control netting and geotextiles — biodegradable coir mats are laid over riverbanks and slopes to stabilize soil while plants establish roots.
• Horticulture — coir pith ("coco coir") is a widely used peat substitute in potting mixes and grow bags.

Coir production is concentrated in a handful of coconut-growing countries. Global output runs over a million tonnes a year, with India and Sri Lanka as the two dominant producers, followed by Vietnam, Thailand and Ghana at much smaller volumes. India's Kerala coast produces the large majority of the world's white coir, while Sri Lanka is the leading source of brown coir. Both countries have long-established processing industries, cooperatives and export infrastructure built specifically around this one fiber.

Both are genuine waste-stream fibers — coir from a food byproduct (the coconut husk), banana fiber from an agricultural byproduct (the pseudostem left after fruit harvest) — which is part of why they're so often mentioned in the same breath. But they sit at opposite ends of the strength spectrum: coir trades tensile strength for rot- and saltwater-resistance, while banana fiber trades some of that moisture tolerance for roughly three to four times the raw tensile strength and a finer, glossier hand that takes dye well. We cover the full side-by-side, including care differences, in Banana Fiber vs. Coir: How the Two Byproduct Fibers Compare, and coir's place in the wider natural-fibre family is mapped out in our complete guide to types of natural fibers.

Combed Banana Fiber

If you're sourcing a natural fiber for rope, woven goods or craft use and want higher raw tensile strength than coir offers, this is the raw material we actually supply: combed, 6-filament banana fiber, 2–5 feet long, graded from partner-farm pseudostems in Sindh (PKR 1,960, currently in stock).
