COIR PRODUCTS EXPORT OPPORTUNITIES DR.J.ANANDHA KUMAR Lecturer, Department of Textile Processing, GRG Polytechnic College
Abstract Coir is a versatile lingo-cellulosic fiber obtained from coconut trees (Cocos nucifera). Coir is available in large quantities, in the order of 5 million tons a year globally. The export of coir and coir products from India was Rs. 2757.90 crore for the year 2019-20. Registering an all-time high record, which was around Rs. 30 crores higher than that of the last year i.e., 2018-19 at Rs. 2728.04 crore. While the exports of coir pith, tufted mats, coir Geo-textiles, coir rugs and carpets, coir ropes and power-loom mats grew both in terms of quantity and value. The products like hand-loom mats, coir yarn, rubberized coir and power-loom matting showed a decline in terms of the quantity and increase in terms of value. Coir pith with export earnings of Rs. 1349.63 crore constituted 49% of the total export of coir products from the country. The value-added items put together constituted 33% of the total exports. The best way to bring the existing coir industry to a higher level is the development of new value-added coir products. This review article throws light on the opportunities in coir spinning and the various value-added coir products for Export. Introduction Coir is the fibre obtained from the fruit of coconut tree (Cocos nucifera). It belongs to the palm tree family (Arecaceae) grown in tropical and sub-tropical countries [1]. Coconut fruit consists of exocarp (the outer husk), mesocarp (the fibrous husk), endocarp (the hard shell) and the endosperm (the meat) [2]. Coir fibre is extracted from the coconut fruit after the removal of husk after the removal of the endocarp and the endosperm. The husk consists of 75%

of fibre material and 25% fine material called pith [3]. Though coconut tree grows in several countries, majority of fibre extraction takes place in countries like India, Sri Lanka and Philippines. Less than 50% of coconut husk are utilised for fibre extraction and remaining husks are used as domestic fuel and left over as waste which decomposes in due course of time. Coir fibre consists of 43.44% of cellulose, 45.84% of lignin, 0.25% of hemi cellulose, 3.00% of pectin, 2.20% of ash and 5.25% of watersoluble compounds [4]. Due to the high quantity of lignin, coir fibre is brown, stiff and has high flexural rigidity [5]. Two types of of course fibres are available in the coir industry like white fibre and brown fibre [6]. Fibre obtained from the immature green husk after a long retting process of 10 to 12 month is known as white fibres. Brown fibres are extracted from matured husk with a getting process of 10 days. Spinning of coir fibres has been carried out in India, Sri Lanka and Thailand. Coir fibre yarn is produced by the traditional hand spinning process and the mechanised spinning process. Hand spinning is being carried out by women workers in the rural regions of Kerala and provides livelihood to a sizable women population. Mechanised spinning process has got its importance as the demand for coir yarns is not fulfilled by the low production of hand spinning process [7]. Most of the white fibres are processed in hand spinning and the brown fibres are processed in the mechanised spinning system. Coir Fibre Industry in India Coir Industry in India, manufactures yarns, mats, mattings and other products using age-old processes due
to which the quality of the products leaves much to be desired. The fibre properties and chemical composition are given below in Table 1. and Table 2. respectively: Table 1. Physical Properties of Coir Fibers

Spinning Spinning is mostly done manually. The output is low, and the nature of work is tiresome. Mechanised ratts are available, but in most of the cases, the quality of yarns from these ratts does not conform to the exporter’s quality requirements. Majority of the coir yarns
