What is PP/PET staple fiber non woven geotextile?

Nonwoven geotextile fabrics have a variety of raw materials and processing techniques, making them very versatile. From the processing technology, geotextiles can be divided into four categories: woven geotextiles, non-woven geotextiles, synthetic geotextiles and composite geotextiles. Nonwoven geotextile fabric products have the largest application volume and the widest application field.

Among them, staple fiber non woven geotextile fabric is made of polyester or polypropylene staple fiber by needle-punching consolidation, which has good mechanical properties that are uniform in all directions. At the same time, it has a wide range of pore size, tortuous pore distribution, excellent permeability and filtration performance, as well as high chemical stability properties such as biological resistance, acid and alkali resistance, and aging resistance.

PET staple fiber non woven geotextile has been widely used in major water conservancy, transportation and civil engineering due to its outstanding role in protection, reinforcement, seepage prevention and drainage. PP staple fiber non woven geotextile has high strength, low density, excellent low temperature resistance, corrosion resistance and abrasion resistance, and also has good hydrophobic properties and wicking effect, making it have better drainage performance.

What are the basic properties of nonwoven geotextile fabric (staple fiber) ?

1. High strength: Due to the use of plastic fibers, it can maintain full strength and elongation in both dry and wet conditions.
2. Corrosion resistance: It can resist corrosion for a long time in soil and water with different pH degrees.
3. Good water permeability: It has a wide range of pore sizes and a tortuous pore distribution

4. Good anti-microbial: It is not damaged by microorganisms and insects.
5. Convenient construction: Due to the light and soft material, it is convenient to transport, lay and construct.
6. Complete specifications: Width up to 7 meters. Mass per unit area: 100-1000g/m².

6) Soft foundation treatment of port engineering, reinforcement and drainage of beach embankments, harbor wharves and breakwaters.

Technical Data Sheet

When to Use Filament Geotextile and When to Use Staple Fiber Geotextile?

Choosing between filament geotextile and staple fiber geotextile mainly depends on the specific needs and conditions of the project. Below are some typical scenarios and explanations, along with specific performance parameters to assist in understanding:

Filament Geotextile

1.Projects Requiring High Strength:

• Example: Highways, airport runways, port terminals, and other situations requiring high strength and durability.
• Reason: Filament geotextile is made from continuous filament fibers, offering high tensile strength, usually above 20-40 kN/m, and puncture resistance up to 500-1500 N. This ensures structural stability under heavy loads and high pressure, reducing the risk of damage.

2.Long-Term Use with High Durability Requirements:

• Example: Landfills, soil reinforcement, coastal protection, and other projects requiring long-term stability.
• Reason: Filament geotextile has excellent aging resistance, with UV aging strength retention rates above 70%, allowing it to maintain good physical and chemical properties over long-term exposure or burial, ensuring the project's longevity.

3.Filtration and Drainage Projects:

• Example: Reservoirs, riverbank protection, drainage channels, and other scenarios requiring effective filtration and drainage.
• Reason: Filament geotextile offers good permeability, with a vertical permeability coefficient typically above 10^-3 cm/s, and a porosity greater than 70%, effectively preventing soil particles from entering the drainage system while ensuring smooth water flow.

Staple Fiber Geotextile

1.Cost-Sensitive Short-Term or Small Projects:

• Example: Temporary road reinforcement, simple cofferdams, protective layers under liners, etc.
• Reason: Staple fiber geotextile has a relatively simple manufacturing process, with unit weight typically between 100-600 g/m² and tensile strength generally between 10-20 kN/m. It is cost-effective, making it suitable for budget-limited or short-duration projects.

2.Soil Separation Projects:

• Example: Railway subgrades, road subbases, and other projects requiring soil separation.
• Reason: Staple fiber geotextile effectively prevents the mixing of soil layers with different particle sizes, offering moderate tensile strength (10-20 kN/m) and permeability (vertical permeability coefficient around 10^-2 cm/s), meeting general separation requirements.

3.Erosion Control and Slope Protection:

• Example: Riverbank protection, slope stabilization, and other scenarios requiring soil erosion prevention.
• Reason: Staple fiber geotextile can be quickly laid to prevent soil loss due to rainwater erosion. Its lightweight unit weight, typically between 100-300 g/m², makes it adaptable to certain terrain changes and easy to construct.

Filament Geotextile: Suitable for projects requiring high strength (20-40 kN/m and above), high durability (UV aging strength retention rate above 70%), and long-term performance, typically used in heavy-duty, long-term, filtration, and drainage scenarios.

Staple Fiber Geotextile: Suitable for lower-budget, short-term, or small projects, offering moderate strength (10-20 kN/m), permeability (vertical permeability coefficient 10^-2 cm/s), and is more suitable for general soil separation and erosion control.

Choosing the right type of geotextile based on the specific needs of the project can effectively improve the quality and cost-effectiveness of the project.
