Non Woven Filter Fabric
Description
What is filament non woven geotextile?
Geotextiles are weaving, non-woven or weaving methods that make fibers or yarns into continuous flat materials. Non woven filter fabrics are widely used in railways, highways, water conservancy, mining and metallurgy and environmental protection and other major projects related to the national economy and people's livelihood, and have important roles such as reinforcement, filtration, drainage, protection and separation. Geotextiles can be divided into filament geotextiles and short-filament geotextiles according to the length of their fibers, which are obtained by filament spunbond and staple fiber wrapping respectively. Compared with short-fiber geotextiles, the geotextiles prepared by filament spunbond have the characteristics of uniform texture, high tensile strength and high production efficiency.
Non woven filter fabric (Filament) is a new type of building material used in civil engineering, which is laid into a network by filament fibers through different equipment and processes, and then intertwined with each other through acupuncture and moxibustion and other processes, so that different fibers are intertwined and fixed with each other, so that the fabric is standardized, and the fabric is soft, plump, thick and tough, so as to achieve different thicknesses and meet the requirements of use.
PP filament non woven geotextile have high chemical stability, strength and density, which makes them occupy an important position in water conservancy engineering, geotechnical engineering and geological environment engineering. PET filament non woven geotextile has good mechanical properties, freeze-thaw resistance, and photo-oxidation aging resistance.

Differences Between Filament and Short-Fiber Non Woven Geotextiles
Filament geotextiles and short-fiber geotextiles differ significantly in manufacturing processes, performance characteristics, and applications. Here are the main differences between these two types of geotextiles:
1. Manufacturing Processes
Filament Geotextiles:
Material: Filament geotextiles are made from continuous long fibers through processes such as needle punching, heat bonding, or other methods.
Manufacturing Process: The production process typically includes spinning, needle punching, and heat bonding. These long fibers remain continuous throughout the production process, resulting in higher strength and durability.
Short-Fiber Geotextiles:
Material: Short-fiber geotextiles are made from short fibers through processes such as needle punching or other methods.
Manufacturing Process: The production process is relatively simple, involving the random distribution and needle punching of short fibers to form the geotextile. Due to the shorter fibers, the material's strength and durability are relatively lower, but the manufacturing cost is lower.
2. Performance Characteristics
Filament Geotextiles:
Strength: Filament geotextiles have high tensile strength and tear resistance, making them suitable for applications requiring high strength.
Durability: The continuous fiber structure provides higher durability and longevity in long-term use.
Permeability: Generally, filament geotextiles have good permeability, allowing for effective filtration and drainage.
Short-Fiber Geotextiles:
Strength: Short-fiber geotextiles have lower tensile strength and tear resistance, suitable for general geotechnical applications.
Durability: Although less durable than filament geotextiles, short-fiber geotextiles still perform well in various engineering environments.
Permeability: Short-fiber geotextiles typically have good permeability, suitable for drainage and filtration applications.
3. Applications
Filament Geotextiles:
Road and Railway Construction: Used for subgrade reinforcement and separation, providing high strength and durability.
Dams and River Engineering: Used for protection and reinforcement, offering excellent erosion resistance.
Landfills: Used for lining and protection, providing long-term durability and stability.
Bridge and Tunnel Engineering: Used for foundation reinforcement and protection.
Short-Fiber Geotextiles:
Drainage Systems: Used for drainage and filtration, offering good permeability and filtration performance.
Landscape Engineering: Used for soil stabilization and protection, suitable for general landscaping and greening projects.
Temporary Works: Used for short-term projects, such as temporary roads and construction site protection.
4. Comparative Data
| Performance Parameter | Filament Geotextiles | Short-Fiber Geotextiles |
|---|---|---|
| Tensile Strength | 20-80 kN/m | 10-40 kN/m |
| Tear Resistance | High | Medium |
| Permeability | High | High |
| Durability | High | Medium |
| Manufacturing Cost | Higher | Lower |
Filament and short-fiber geotextiles each have their advantages and are suitable for different engineering needs. Filament geotextiles, with their high strength and durability, are ideal for projects requiring high strength and long-term use. Short-fiber geotextiles, with their lower manufacturing cost and good permeability, are suitable for general engineering and short-term projects. Selecting the appropriate type of geotextile based on specific engineering requirements ensures the stability and longevity of the project.
