stabilisation of soil using hybrid needlepunched nonwoven geotextiles

in the past, natural and synthetic fibre based geotextiles have been used for short- and long-term applications of soil erosion. it is well known that these geotextiles complement each other in terms of various physical and mechanical properties. in this study, an attempt has been made to study various properties of hybrid geotextiles. these hybrid geotextiles have been produced from the blend of polypropylene/viscose and polyester/viscose fibres in defined weight proportions (0%, 20%, 40%, 60%, 80% and 100%). subsequently, a comparison has been made between various physical and mechanical properties of needlepunched nonwoven geotextiles. in this research work, it was found that hybrid geotextiles made of viscose (up to 40 wt.%) can replace 100% polypropylene or polyester based geotextiles.
