coir

noun

1. (countable, uncountable)The fibre obtained from the husk of a coconut, used chiefly in making rope, matting and as a peat substitute.

   “Then, how comparatively sweet was everything on board - no paint, no tar, no new rope, (vilest of smells to the qualmish!) no grease, or oil, or varnish; but instead of these, bamboo and rattan, and coir rope and palm thatch; pure vegetable fibres, which smell pleasantly if they smell at all, and recall quiet scenes in the green and shady forest.”
