PET filament geotextiles are manufactured using polyester, which is a type of polymer derived from petroleum. Polyester is a versatile material with excellent physical and mechanical properties, making it suitable for geosynthetic applications. The PET filaments are formed into a nonwoven structure through a combination of mechanical processes, heat, and bonding agents.Polyester filament geotextile is a type of geosynthetic material made from polyester filaments. It is commonly used in civil engineering and construction projects for soil stabilization, erosion control, and reinforcement applications. Polyester filament geotextile is known for its high tensile strength, excellent durability, and resistance to UV radiation and biological degradation
