What are the differences between staple fiber geotextile and filament geotextile?
What are the differences between staple fiber geotextile and filament geotextile?
Basic Information
Staple fiber needle-punched geotextile: GB/T 17638-2017
Polyester filament spunbond needle-punched geotextile: GB/T 17639-2023
Core Comparison Table (for foreign trade catalog)
Comparison Items | Staple Fiber Geotextile | Filament Spunbond Geotextile |
Raw Material & Production Process | Polyester/PP staple fibers (several centimeters long) → carding & web laying → needle punching | Continuous filaments extruded directly from polyester chips → web forming → integrated needle punching |
Strength at the same weight | Medium; average CBR burst strength | Higher; tensile and burst strength is 30%~50% higher at the same weight with uniform performance |
Elongation | Relatively high, 50%–100%; flexible with good deformation adaptability | Moderate, 20%–80%; stable under loading |
Creep Resistance & Durability | General; obvious strength attenuation under long-term load | Excellent; anti-aging and low creep, suitable for century-long permanent projects |
Pore Structure & Filtration | Rich pores, ideal for filtration and drainage of fine-grained soil | Uniform pore size, stable hydraulic performance and low clogging risk |
Price | Cost-effective, lower price | 20%~30% more expensive |
Appearance | Fuzzy, dark surface, felt-like texture | Whiter surface, visible continuous filaments, smooth texture |
Application Scenarios
Staple Fiber Geotextile (Main functions: filtration, separation, protection, drainage)
Protective layer for HDPE geomembranes in landfills, wrapping for blind drains
Filtration for river slope protection, drainage ditches, general municipal road subgrade separation
Landscape projects, artificial lakes, temporary works and budget-limited projects
Filament Spunbond Geotextile (Main functions: reinforcement, heavy load, high-standard permanent works)
Soft soil treatment for high-speed railways, expressways, airports and port yards
Large hydraulic dams, tailings ponds, reinforced soil retaining walls
Key projects requiring stable long-term performance, low creep and high tear resistance
Quick Selection Guide
Choose staple fiber geotextile for regular filtration, membrane protection and cost control; Choose filament spunbond geotextile for heavy-duty subgrade, railway/hydraulic projects and long-term durability requirements.
