What is geotextile?

As the name implies, geotextile is a geosynthetic fabric that differs greatly from the production methods of geotextiles and composite membranes. According to its production process, it can be divided into woven fabrics and non-woven fabrics. Generally speaking, geotextiles refer to non-woven fabrics(China Geofabrics Vendor) made by repeated needle-punching processes. In addition, woven fabrics refer to woven geotextiles such as woven fabrics and woven fabrics. The woven fabrics here are commonly used grass control cloths for farmers. , weeding cloth. Then, according to the raw material, the non-woven fabric can be classified into a short needle-punched nonwoven fabric and a filament-spun needle-punched nonwoven fabric.

Geotextile function

Since the geotextile(Non Woven Geotextile On Sales) is a process of repeated needling, it has a three-dimensional pore structure. We used to call it the equivalent aperture. The equivalent pore diameter of the staple fiber cloth is usually in the range of 0.07 to 0.2 mm, and the equivalent pore diameter of the filament cloth is in the range of 0.05 to 0.2 mm. Its three-dimensional structure makes it have good water permeability, so the actual user also calls it a permeable geotextile. Because it has good breaking strength, it refers to tension, so its main role is to strengthen and protect. In addition, it has the main role of permeable soil, which is called "reverse filtration". In summary, the non-woven fabric has water permeability, enhanced protection and anti-filtration function.

It has been reported that as early as the 1970s and 1980s, European geotextiles were widely used in various projects such as traffic roads, airport runways, dikes and slope protection. With the rapid development of China's economy, geotextiles(Non Woven Filter Fabric Factory) with low cost and good effect have become the first choice for civil engineering in various fields of civil construction.
