| Abstract/Contents: | "India produces the best quality of coir fibre (Cocos nucifera) by retting the matured green coconut husks in waters for 6 to 10 months. It is mostly used for manufacture of mats, mattings and carpets. This fibre is free from toxic phenolic materials which are usually present on the surface of brown fibre, extracted mechanically from dry husk. The retted fibre is also comparatively less sensitive to UV light due to leaching out of photo-sensitive materials from its surface during retting process. Yarn made out of retted fibre has superior strength compared to the yarn made out of brown fibre. Recently a unique process has been developed by Central Coir Research Institute of Coir Board by which green husk fibre can be retted by Coirret (a bacterial cocktail) within 72 hrs. A wide variety of geotextiles ranging in densities from 400 to 1400 grams/m₂ of coir nettings can be made for different applications. Experiments were conducted in 1995 at three different sites using coir nettings as erosion control material. A canal bank and road slope at two different sites were chosed for this purpose It was observed that the area treated with coir geotextiles in the three locations was free from soil erosion when compared to other areas elsewhere thus establishing the fact that coir is an ideal geotextile. The lemon grass root slips were used for vegetating the soil on the canal bank of area 370 m₂ (Experiment I), a nearby road slope of area 800 m₂ (Experiment II) and vetiver grass slips were used at a different place on a very steep slope of area 600 m₂ (Experiment III). The study revealed that the nutrients of the soil increased due to degradation of coir nettings and substantial growth of grass was observed in the areas under experiment. It has been observed that the material maintains the pH balance of the soil and becomes part of it after vegetation grows. The material due to its weight and capability to absorb water conforms closely to the contour of the soil surface. The hairiness of the yarn also contributes to holding soil particles in place. The woven construction of coir nettings allows intersecting strands to move independently of one another which reduces the risk of wild life entrapment also." |
