Filament non woven geotextile is a type of geotextile made from continuous filaments of either polyester (PET) or polypropylene (PP) fibers. These filaments are entangled together using a needle-punching process, resulting in a strong and durable fabric with excellent water permeability. Here are some key points about filament nonwoven geotextile:
Material Composition:
- Polyester (PET) or polypropylene (PP) fibers are used.
- These fibers are continuous and not cut into shorter lengths.
Manufacturing Process:
- Filament nonwoven geotextile is created through a needle-punching process.
- During this process, the continuous filaments are mechanically entangled, forming a cohesive fabric.
Properties:
- Tensile Strength: Filament nonwoven geotextile exhibits excellent tensile strength, making it suitable for various applications.
- Tear Resistance: It resists tearing and damage.
- Filtration and Drainage: The fabric allows water to pass through while retaining soil particles.
Applications:
- Soil Stabilization: Used to reinforce soil and prevent erosion.
- Erosion Control: Helps stabilize slopes, riverbanks, and embankments.
- Road Construction: Provides separation and filtration functions in road base layers.
