Description

Introduction

Needle-punched PET filament geotextile is a specific type of geotextile made from polyester (PET) filaments through a needle-punching process. In this manufacturing technique, continuous PET filaments are mechanically entangled with one another using barbed needles, forming a non-woven fabric structure.

PET Long fiber geotextile was made from virgin polyester chips, the continous filament was extruded from polyester chip by machine directly by spunbond process. Pet Long Fiber Nonwoven Geotextile punch together to get the stable 3D with highter strength fabric . so Nonwoven Geotextile Fiber has high strength , good creep property excellent and erosio resistance, aging-resistance and heat resistance.

Applications

1.Non-Woven Structure: Unlike woven geotextiles, needle-punched geotextiles have a non-woven structure, which means the filaments are not interlaced in a traditional weaving pattern but rather entangled through mechanical processes.

2.High Strength: Despite being non-woven, needle-punched PET filament geotextiles offer high tensile strength and puncture resistance, making them suitable for applications requiring reinforcement and stabilization of soil.

3.Permeability: Needle-punched geotextiles maintain permeability, allowing water to pass through while providing effective filtration to prevent soil erosion and clogging of drainage systems.

4.Dimensional Stability: These geotextiles exhibit good dimensional stability, maintaining their shape and structure under various environmental conditions.

5.Chemical Resistance: PET filaments provide resistance to chemical degradation, enhancing the durability and longevity of the geotextile in harsh environments.

6.Versatility: Needle-punched PET filament geotextiles find applications in a wide range of civil engineering projects, including road construction, embankment stabilization, erosion control, landscaping, and drainage systems.
