Abstract: A simple machine has been developed at the Textile Technology Department of IIT Delhi that uses coir and jute yarns to manufacture 100% natural fibre strip drains. The machine employing braiding technology braids jute yarns to form the filter sheath and coir yarn as core. Typically the drains are about 7.5-12.5 mm thick in dry state and have a tensile strength of above 3 kN. The properties of the drain have been studied in comparison with two synthetic strip drains and another type of natural fibre strip drain. In general, the properties of this drain are found comparable with typical synthetic drains, except that for a slightly lower discharge capacity under soil confinement. An important feature of the jute yarn sheath is its swelling nature that allows it to function as filter without clogging. The present drain differs from the other natural fibre sheath drain is that it is manufactured in single machine, and has capability of varying the width, thickness and weight per linear meter to suit different soil conditions.
