Non-Woven Geotextiles
Needle-Punched or Thermally Bonded Fabrics for Drainage, Separation & Protection
Overview
Non-woven geotextiles are manufactured from synthetic fibers that are mechanically entangled or thermally bonded to form porous and durable fabrics. These textiles are designed for applications involving filtration, drainage, protection, or separation where permeability and strength are critical. Filtech Textiles provides a wide range of non-woven geotextiles tailored to civil engineering, water management, and environmental protection projects.
Types of Non-Woven Geotextile Fabrics
- Polypropylene (PP): Lightweight, chemically inert, and hydrophobic — ideal for drainage and barrier layers.
- Polyester (PET): High mechanical strength and temperature resistance — suitable for underdrains and erosion control.
- PET-PP Blends: Balanced strength, stability, and economic performance — used in multi-functional construction layers.
Key Features
- Available in GSM range from 80 to 1000
- Excellent filtration and permeability properties
- Thermal bonding or needle-punching options
- Roll widths up to 5.2 meters for large projects
- Resistant to biological and chemical degradation
Filter Media Specification for Woven Geotextiles
| Material | GSM Range | Advantages | Limitations |
|---|---|---|---|
| Polypropylene (PP) | 80 – 600 GSM | Excellent chemical resistance, hydrophobic, economical, lightweight | Limited UV resistance without stabilization |
| Polyester (PET) | 100 – 800 GSM | High strength, dimensional stability, suitable for high-temp zones | Moderate resistance to strong alkalis |
| PET-PP Blends | 100 – 700 GSM | Balanced durability and filtration, improved elongation and strength | Not suitable for highly acidic/alkaline environments |
Applications of Non-Woven Geotextiles
