Long Fiber Geotextile - PET Engineering Fabric for Environmental & Infrastructure Projects

Raw Material & Manufacturing Process

• Raw material: High-purity PET polyester chips, selected for their high strength, low shrinkage, and chemical stability.
• Manufacturing process: Chips are melted, extruded into continuous filaments, stretched to optimize strength, laid into a web, and needle-punched to form a cohesive fabric.
• The needle-punching step ensures the fabric retains its shape and performance under various mechanical and environmental stresses.

Key Performance Features

• High tensile strength: Can withstand heavy loads and lateral stresses in large-scale infrastructure projects.
• Anti-aging properties: Resists UV degradation and environmental wear, suitable for long-term outdoor applications.
• Acid and alkali resistance: Suitable for use in soil or water with high chemical content (e.g., saline-alkali marshes, industrial waste sites).
• Flexibility: Easy to handle and install on uneven or sloped surfaces, reducing construction complexity.

Typical Application Scenarios

• Environmental remediation: Heavy metal 治理 landfills, tailings pond capping, and saline-alkali soil improvement projects.
• Transportation: Highway and railway subgrades for drainage, soil separation, and reinforcement.
• Hydraulic engineering: Coastal protection works, river embankments, and dam construction for filtration and erosion control.

Product Specifications

• Weight per square meter: 100g ~ 800g
• Width: 1.0m ~ 6.6m
• Roll length: 50m ~ 200m (custom lengths can be provided based on user requirements)
