Black long fiber geotextile is a high-performance geosynthetic material manufactured from polyester filaments using advanced needling reinforcement technology. This engineering fabric delivers exceptional mechanical properties, superior water permeability, and outstanding resistance to corrosion and aging, making it ideal for demanding civil engineering applications.

• High Tensile Strength: Excellent mechanical properties with high tensile strength and elastic modulus to withstand external forces
• Temperature Resistance: Maintains performance across wide temperature ranges from -40°C to 120°C
• Chemical Resistance: Superior alkali resistance after surface coating treatment
• Environmental Safety: Contains no chemical additives and requires no heat treatment

• Transportation Infrastructure: Highway and railway construction for roadbed reinforcement, cost reduction, and prevention of reflection cracks
• Hydraulic Engineering: Dams, river channels, coastlines, and retaining walls as drainage layers while preventing soil particle migration
• Separation Function: Isolation between railway ballast and subgrade, airport surfaces and bases, and different dam materials
• Reinforcement Function: Soil stress distribution and lateral displacement prevention in slopes, embankments, and retaining walls
• Erosion Control: Riverbank protection against wind, waves, and rainfall erosion
