Coir (also known as "Kokos" or "Coco") is a natural fiber extracted from the husk of Coconut fruit. The husk consists of Coir fiber and a corky tissue called pith. The husk is immersed in water for 6 - 9 months. This process is called retting. Retting removes some of the dirt and natural enzymes present in the fiber giving it a golden color. The fiber is then extracted by beating it manually using a mallet or by a mechanical extractor machine. This leaves the outer skin of the coconut fruit along with the corky pith. Pith finds large scale use in horticulture as a growing medium. The fiber thus extracted is then hand - spun to form the golden coir yarn. This yarn is used to make an ever increasing range of products.
The advantages of coir fibers are
100% natural
Bio - degradable
Made from infinitely replinishable resources
Natural golden brown color - fits any decor
Hard and resilient fiber provides excellent scrubbing action - ideal for door / entrance mat applications
High water retention
Coir mattings and rugs: hard - wearing, rustic and elegant
Moth and rot resistant
Good insulator of heat and sound
