Non-Woven Long Fiber Geotextile: Advanced Filtration, Protection, and Drainage

Product Specification

Introduction: Next-Generation Geosynthetic Performance
Experience the superior engineering of our non-woven long fiber geotextiles, manufactured using advanced spunbond technology for consistent quality and enhanced performance. Unlike staple fiber alternatives, these geotextiles are formed from continuous filament fibers that are mechanically bonded and heat-calendered, creating a dimensionally stable fabric with exceptional mechanical properties. Designed for critical filtration, separation, protection, and drainage applications, our long fiber geotextiles deliver reliable performance in demanding environmental and civil engineering projects.

Advanced Manufacturing and Technical Excellence

1. Continuous Filament Superiority
Our geotextiles are produced from continuous polyester or polypropylene filaments, not short staple fibers. This manufacturing approach creates a more uniform fabric with consistent pore size distribution and higher tensile strength per unit weight, resulting in predictable, engineered performance.

2. Optimized Pore Structure for Precision Filtration
The controlled production process creates a precisely engineered pore size distribution that provides excellent filtration characteristics. The geotextile effectively retains soil particles while maintaining optimal water flow, preventing soil migration and system clogging in drainage applications.

3. Enhanced Mechanical Properties
The continuous filament structure provides:

• Higher Tensile Strength: Superior resistance to installation stresses and long-term loading

• Excellent Puncture and Tear Resistance: Withstands aggressive subgrade conditions and heavy aggregate placement

• Multi-Directional Strength: Uniform properties in all directions due to random fiber orientation

4. Consistent Thickness and Porosity
The heat-calendering process creates a uniform product with consistent thickness and porosity across entire rolls and between production batches. This consistency ensures predictable flow rates and filtration performance throughout your project.

Performance Advantages in Demanding Applications

1. Superior Filtration and Drainage Performance
The three-dimensional matrix of interconnected pores provides:

• High Permittivity: Efficient cross-plane water flow

• Excellent Transmissivity: Effective in-plane water transport

• Clogging Resistance: Maintains performance over decades of service

2. Exceptional Protection Capabilities
The combination of thickness, puncture resistance, and tensile strength makes it an ideal protective layer for geomembranes and other sensitive lining systems. It effectively distributes point loads and prevents damage from sharp objects and irregular subgrades.

3. Durability in Challenging Environments

• UV Resistance: Contains carbon black or other UV stabilizers for extended exposed performance

• Chemical Resistance: Resists degradation from soil chemicals and leachates

• Biological Resistance: Immune to microbial attack and rotting

4. Installation Advantages
The continuous filament construction provides:

• Better Handleability: Reduced tendency to tear during installation

• Edge Stability: Minimal fraying during cutting and placement

• Consistent Unrolling: Smooth deployment without bunching or twisting
