1. What Is A Continuous Filament Non Woven Geotextile

Continuous Filament Non Woven Geotextile is an advanced geosynthetic material crafted from continuous polypropylene or polyester filaments. These filaments are uniformly spun over a flat surface and thermally bonded together to form a cohesive, tear-resistant fabric. Unlike woven geotextiles, this material is not woven but rather formed through a continuous process that enhances its strength and durability.

1.1 Manufacturing Process

The production of Continuous Filament Non Woven Geotextile involves several key steps:

Fiber Production: Polypropylene or polyester resin is melted and extruded through fine nozzles to form continuous filaments.
Fiber Spreading: These filaments are spread out to form a uniform web on a flat surface.
Thermal Bonding: The web is passed through heated rollers or ovens, thermally bonding the fibers together to create a stable network.

This meticulous manufacturing process ensures the geotextile possesses excellent uniformity, puncture resistance, and filtration efficiencies.

5. What Is The Difference Between Short Fiber and Continuous Filament Nonwoven Geotextile?

The fundamental difference between short fiber and Continuous Filament Nonwoven Geotextile lies in the length of the fibers used to construct the fabric, which significantly impacts their respective properties and applications:

5.1 Fiber Length and Manufacturing

Short Fiber Nonwoven Geotextile:Made from staple fibers, which are short, cut lengths of synthetic polymers (typically a few centimeters long). These short fibers are mechanically entangled through needle punching or thermally bonded to create the fabric.
Continuous Filament Nonwoven Geotextile:Constructed from continuous, unbroken strands of synthetic polymers that are spun directly into a web and then bonded thermally, mechanically, or chemically. The filaments run the entire length of the fabric roll.

5.2 Key Property Differences

No	Feature	Short Fiber Nonwoven Geotextile	Continuous Filament Nonwoven Geotextile
1	Fiber Length	Short, cut staple fibers	Long, continuous filaments
2	Tensile Strength	Generally lower to medium	Generally higher
3	Creep Resistance	Lower	Higher
4	Dimensional Stability	Lower	Higher
5	Uniformity	Can be less uniform due to random fiber orientation	Generally more uniform due to controlled filament placement
6	Filtration Efficiency	Good, often used primarily for filtration	Excellent, engineered for both filtration and reinforcement
7	Permeability	Generally high	Can be engineered for a range of permeability
8	Puncture Resistance	Moderate	Good to high
9	Tear Resistance	Moderate	Good
10	Cost	Generally lower	Generally higher due to the more complex manufacturing process
11	Primary Applications	Filtration, separation, basic soil stabilization	Reinforcement, critical filtration, long-term stability

In essence, Continuous Filament Nonwoven Geotextiles are engineered for higher performance and long-term durability in demanding applications where strength, creep resistance, and predictable behavior are critical. Short fiber nonwoven geotextiles are often favored for applications where filtration and separation are the primary requirements, and cost is a more significant factor. As leading Geotextile Manufacturers, we offer both types to cater to the diverse needs of the construction industry.
