Optimization of Production Parameters for Manufacturing Polypropylene based Needle Punched Nonwoven Geosheet and Analysing Their Physical and Mechanical Properties

Needle punched nonwoven geotextiles exhibit the best performance parameters compared to other structures when used in civil engineering applications, drainage, filtration, soil protection, erosion control, river bank protection, river training, coastal protection and providing reinforcement. Besides, the physical and mechanical characteristics significantly influence the performance & functionality of the product. There is a significant correlation between the mechanical properties of geo-textiles & their aerial mass. In this paper, different production parameters such as feed rate, needle penetration, stroke frequency has been optimized for manufacturing polypropylene based geosheet samples of different aerial mass which are used to produce geobags by stitching for sand filling and also their various properties has been analyzed.
