Now a days, synthetic fibers such as glass fibers, carbon fibers and Kevlar fibers are being highly used in the manufacturing of reinforced plastic products for applications ranging from aerospace industries, for building construction, to transportation and packaging. But the high cost of these fibers is a constraint for low cost applications. It is therefore, worthwhile to look for cheaper substitutes for such fibers in developing countries such as India. Coir, the hard, versatile, natural fiber which is abundantly available in India can be a best solution for this problem. The properties of coir such as Abrasion resistance, UV rays proof, salt water resistance, durability, biodegradable, high tenacity, ability to hold water shows it as…show more content…
Curled coir is used in the manufacture of rubberized coir pads used for upholstery. It is also used to prepare simulated animal hair and as packaging material as well as for thermal Insulation. By studies it is identified that coir can also used as a material to control soil-erosion, rail embankments and on the slopes of high-ways. Now the extreme usage of bi-products of coir, like coir pith is also identified and is used for various applications. With the improved understanding of properties of the fiber, it may be possible to find new uses for…show more content…
Retting, is an important process in the production of coir fibre,which is a biological process that can be done in fresh water or in saline water, flowing water or stagnant water, deep waters or back waters during any time of the year. The husks are placed for retting process in upright position in coir nets or pits. Quality of the coir varies according to the retting process. In Saline water, after retting, stronger and golden yellow colour coir will be produced. The retting process of fibers obtained from husks placed in fresh water will be incomplete resulting to same amount of pith adhering to the fibre.In Stagnant water,the coir fibre will become weak. Husks soaked in back waters and placed in upright position in coir nets yields better quality fibres, in terms of color as well as strength.(2) There are two varieties of Coir: BROWN COIR Brown coir fiber will be thick and strong and is obtained from fully ripened coconuts which will have high abrasion resistance . It is typically used in mats, brushes and sacking. Mature brown coir fibers contain more lignin and less cellulose than fibers such as flax and cotton and will be stronger but less flexible.(1) WHITE COIR White coir fibers are obtained from the coconuts before they ripe. These fibers are white or light brown in color and are smoother and finer, but also weaker. They are generally
