Abstract

Coir, the fibre extracted from the mesocarp of the drupe of the coconut palm cocos nucifera is used for the production of beautiful products like mats, matting, carpet, handicrafts etc. (Table I) Coir suits very well for geotextiles and insulating materials and being environment friendly has an edge over synthetics for application in environmental operations.

Abstract

White coir fibre is extracted from coconut husks after 'retting' for a period varying between six to ten months depending upon several environmental factors. With a view to explore the possibility of reducing the prolonged period required for retting and improving the quality of the coir fibre a field study was conducted at Azhikode in the N. Parur regions of Kerala which is a 'poor'* retting area. Selected strains of efficient pectin and phenol degrading bacterial cultures were inoculated into pits containing lots of husks soaked for retting. Samples of husks were analysed at regular intervals for details of degradation of the husk constituents holding the individual fibres together. It was observed that inoculation of the bacterial strains could shorten the period of retting by two and a half months and yield an improved quality of fibre with respect to colour and texture. The detaiis of the experimental field study are presented in this paper.

Abstract

A bacterial consortium developed on coconut husk leachates could ret coconut husk steeped for retting in rap water in a period of three months. The quality of the coir fibre obtained was comparable to traditionally retted fibre. The consortia could also bestow a greater degree of softness to the mechanically extracted coir fibre. Coir extraction can therefore be practiced by supplying the consortia for retting of husk for production of fibre and enhance the commercial utilization of the husk in coconut growing regions of Asia.
