1. The production process for brown coir is a 2 - step process unlike the white fiber. This is because brown husks are dry and very hard to break.
2. First the brown husks are fed into the auto feeder. The 1st decorticator breaks the brown husks into small pieces as shown in the picture to the left.
3. This is then stacked on cement concreted floors and is heavily watered. This is left undisturbed for 7 to 10 days. The amount of watering done and the period for which it is left undisturbed determines quality
4. After 10 days , this crude fiber is fed into all the 4 decorticators to produce the brown Coir fiber.
1. Coir fiber is sold in Various grades based on application and also how much the client is willing to pay for.
2. First grade fibers either brown or white has only Long length fibers in the range of 10 to 20 cms. Has very less impurities
3. Lower grade fibers are produced by mixing long length fibers with little amount of Short length fibers also called BABY fibers as explained above. Has more impurities than the 1st Grade.
4. picture to the left shows first grade White fiber. and 2nd Grade brown fiber with more impurities.
