PP Filament Nonwoven Geotextile

What is the Polypropylene Nonwoven Geotextile ？

HX® Polypropylene filament spunbond needle punched nonwoven geotextile is made of polypropylene as the raw material. Through the needle punching process, different fibers are interwoven, entangled, and fixed to standardize the fabric.

Polypropylene filament spunbond needle punched nonwoven geotextile, abbreviated as “PP filament spunbond needle punched nonwoven geotextile”. Its physical and mechanical properties such as fracture strength and puncture resistance have obvious advantages, which are 2-3 times higher than conventional products. It has good acid and alkali resistance and good hot melt adhesion, and is used for reverse filtration, reinforcement, isolation, and drainage in highways, railways, landfill sites, embankments, coastal engineering, and other projects.

What are the types of Nonwoven Geotextile?

Short Fiber Non-Woven Geotextiles: These are manufactured by mechanically orienting and interlocking polypropylene fibers to form a sturdy and dimensionally stable network. These geotextiles are commonly used in applications that require superior filtration and secure soil separation.

Continuous Filament Non-Woven Geotextiles: These are composed of polyester yarns formed into a complex 3D network and then consolidated by needle punching. They are commonly used in road construction, filtration, and drainage systems due to their high permeability and toughness.

Each type of non-woven geotextile has its specific characteristics and applications, so it is crucial to select the right type based on the requirements of the project.

What are the types of filament nonwoven Geotextile?

There are two main types of filament nonwoven geotextiles: needle-punched and hydroentangled.

HX^® Needle-punched filament nonwoven geotextiles are made by entangling continuous filaments of polyester or polypropylene with barbed needles. This process creates a strong, durable fabric with excellent water permeability. Needle-punched filament nonwoven geotextiles are the most common type of filament nonwoven geotextile.
Hydroentangled filament nonwoven geotextiles are made by entangling continuous filaments of polyester or polypropylene with water jets. This process creates a fabric that is similar to needle-punched filament nonwoven geotextiles, but it is often more uniform and has a smoother surface. Hydroentangled filament nonwoven geotextiles are less common than needle-punched filament nonwoven geotextiles, but they are often preferred for applications where a smooth surface is required.

Synonyms or Substitutes：

filament nonwoven geotextile has a few other names, synonyms, and substitutes. Here are a few examples:

Needle-punched geotextile
Hydroentangled geotextile
Continuous filament geotextile
Polypropylene geotextile
Nonwoven geotextile
In general, the term “filament nonwoven geotextile” is the most accurate and descriptive name for this type of material. However, the other names listed above are also used interchangeably and can be considered synonyms.

Where is geotextile fabric used? 

HX^® PP filament spunbond needle punched nonwoven geotextile is made from polypropylene as raw material through processes such as spinning, air flow net laying, and needle punching. High strength, aging resistance, acid and alkali resistance, abrasion resistance, good flexibility, easy construction, widely used in garbage disposal sites, river treatment, slope protection, road maintenance, artificial lake bottom waterproof layer, etc.

Geotextile fabric is widely used in civil engineering and construction projects. Some of the common uses include:
Road Construction: Geotextile fabric helps to stabilize the ground and increase the lifespan of the road by preventing the mixing of sub-base and subgrade layers.
Erosion Control: It can be used to protect soil from erosion, especially on slopes and in areas exposed to water flow.
Drainage: Geotextiles have excellent water permeability and are used in drainage systems to filter out soil particles while allowing water to pass.
Landfill: In landfill sites, geotextile fabric is used to separate different layers and prevent contamination of groundwater.
Reservoirs and lakes: Filament nonwoven geotextile fabric can be used to line reservoirs and lakes to prevent seepage and erosion.
Sports fields: Filament nonwoven geotextile fabric can be used to improve drainage in sports fields and prevent the formation of mud.
Green roofs: Filament nonwoven geotextile fabric can be used to create green roofs, which help to reduce stormwater runoff and improve air quality.Filament nonwoven geotextile fabric is a versatile material that can be used in a variety of applications. It is a strong, durable, and water-permeable fabric that can be used to improve the performance of a variety of structures and systems.

Performance

HX^® PP filament spunbond needle punched nonwoven geotextile has the advantages of high strength, strong resistance to piercing, strong resistance, corrosion resistance, anti-microorganism, aging resistance, high temperature resistance, superior water permeability, filtering, soil preservation and other advantages. Compared with polyester filament geotextile, it has higher strength, stronger tear and puncture resistance, especially acid and alkali resistance. It can be in long-term contact with alkaline materials such as cement, fly ash, and lime, and can maintain stable performance in alkaline environments without hydrolysis.

◆ PP filament spunbond needle punched nonwoven geotextile is a permeable material, so it has good filtration and isolation function;

◆ PP filament spunbond needle punched nonwoven geotextile has good drainage performance due to its fluffy structure;

◆ PP filament spunbond needle punched nonwoven geotextile has good puncture resistance, so it has good protective performance;

◆ PP filament spunbond needle punched nonwoven geotextile has good friction coefficient and tensile strength, and has geotextile reinforcement protection and filtration performance.
