- Key performance comparison
*Manufacturing Process
Non Woven Geotextile:Fibers bonded mechanically (needle-punched), thermally, or chemically.
Woven Geotextile:Fibers woven together (like fabric) on looms.
*Structure
Non Woven Geotextile:Random fiber orientation (felt-like).
Woven Geotextile:Grid-like pattern (warp + weft yarns).
*Primary Function
Non Woven Geotextile:Separation, Filtration, Drainage.
Woven Geotextile:Reinforcement, Stabilization.
*Tensile strength
Non Woven Geotextile:Lower tensile strength, isotropic (similar strength in all directions).
Woven Geotextile:High tensile strength, anisotropic (stronger in machine direction).
*Permeability
Non Woven Geotextile:High (water flows easily through pores).
Woven Geotextile:Low to moderate (dense weave restricts flow).
*Filtration Efficiency
Non Woven Geotextile:Excellent (retains soil while allowing water passage).
Woven Geotextile:Good, but prone to clogging in fine soils.
*Elongation
Non Woven Geotextile:High (stretches more under load).
Woven Geotextile:Low (minimal stretch).
2.Key Properties & Performance
*Hydraulic Behavior (Water Flow):
Non Woven Geotextile: High permeability → Ideal for drainage (e.g., behind retaining walls, under roads).
Woven Geotextile: Lower permeability → Better for erosion control but may require careful soil compatibility.
*Mechanical Strength:
Non Woven Geotextile: Good puncture resistance but lower load capacity → Used for cushioning/protection (e.g., under geomembranes).
Woven Geotextile: High tensile strength → Perfect for soil reinforcement (e.g., steep slopes, embankments).
*Filtration & Soil Retention:
Non Woven Geotextile: Random pores trap soil particles while allowing water → Superior for filtration (e.g., landfill leachate systems).
Woven Geotextile: Uniform pores may clog with fine silts → Requires proper opening size (AOS) selection.
*Durability:
Non Woven Geotetxile are both resist UV/chemical degradation (if made from polypropylene/polyester).
Woven geotextile generally has higher abrasion resistance.
3.Typical Applications
*Road Construction
Non Woven Geotextile : Separation layer between subsoil/aggregate
Woven Geotextile : Base reinforcement for weak subgrades.
*Drainage Systems
Non Woven Geotextile : Wrap for perforated pipes, French drains.
Woven Geotextile : Limited (low permeability).
*Erosion Control
Non Woven Geotextile : Under riprap/armor layers.
Woven Geotextile: Slope stabilization, silt fences.
*Landfills
Non Woven Geotextile: Protection layer for liners, leachate collection.
Woven Geotextile: Reinforcement of cover systems.
*Railway Ballast
Non Woven Geotextile:Separation/filtration beneath tracks.
Woven Geotextile: Trackbed stabilization.
4.How to Choose?
You need drainage, filtration, or separation (e.g., under driveways, behind retaining walls, pond liners).
You need high strength and stabilization (e.g., reinforcing soft soils, building access roads over mud).
*Hybrid Tip: Some projects use both! For example:
Non woven geotextile for drainage + woven geotextile for reinforcement in steep slopes.
5.Quick Reference

6.Summary:
Non woven geotextile:Drainage/Filter (water-centric).
Woven geotextile: Reinforcement (strength-centric).
