Geotextiles and composite geotextiles are of ten used in civil engineering materials. Due to the similar appearance of geotextiles and composite geotextiles, it is unclear what kind of geotextile composite geomembrane composites are used by many customers when choosing which geotextile materials to choose. Geotextile (also known as), the differences and contacts are detailed below.

Differences between geotextiles and composite geotextiles:

First, the production process is different. Geotextiles(Non Woven Geotextile Manufacturer) are mainly divided into filament geotextiles and short filament geotextiles. The filament geotextile is made from polyester chips by high temperature melting, spinneret forming and needle punching. Short fiber geotextiles are made from polyester staple fibers through chaotic equipment - combing - into a network - acupuncture. Therefore, the geotextile is a needle-punching process, and the composite geotextile is made by bonding the upper and lower sides of the PE geotextile or one side of the geotextile, and is a thermal composite process.

Second, the product features are different. Filament geotextiles(Polyester Felt Sheet Factory) and short filament geotextiles are mainly used for filtration, anti-filtration, reinforcement and protection in engineering. Geotextiles are permeable but not waterproof. The composite geotextile has the effect of preventing leakage, waterproofing and isolation, and the composite geotextile is waterproof and impervious.

Third, the product specifications are different. Geotextiles are mainly in the range of 100 g/m2 to 800 g/m2, and composite geotextiles are mainly in the range of 300 g/m2 to 3000 g/m2.

Finally, the implementation standards are different. The national filament geotextile implementation standard is GB / t17639-2008, the short wire geotextile implementation standard is GB / t17638-2008, and the composite geotextile implementation standard is GB / t17642-2008.

The connection between geotextiles and composite geotextiles: Geotextiles(China Non Woven Geotextile Supplier) are used in the production of composite geotextiles. Therefore, the composite geotextile consists of geotextile and PE geotextile, and the appearance is similar.
