Abstract: This paper reports the development in flat weft knitting technology; the design and production of the novel natural fibre geotextiles along with their interactive behaviour in different soil types and conditions. These natural fibre products are found to be much more environment-friendly than their synthetic equivalents; the fibres themselves are a renewable resource and are biodegradable. Such structures would also offer economical benefits to a number of developing countries, where vegetable fibres are grown and cultivated in large quantity. These structures have been designed to provide the highest possible strength in one direction , combined with the ease of handling and laying on site; soil particles interlock with the fabric to such an extent that the soil/fabric interface exhibits greater shearing resistance than the surrounding soil, i.e. the soil/fabric coefficient of interaction is greater than one; a degree of protection to the high strength yarns during installation; a tensile strength in the range of 100-200 kN m⁻¹; and ease of manufacture on conventional textile machines.
