Geotextile is made of synthetic fiber through acupuncture or woven with water permeability cloth, commonly known as geotextile also known as geotextile. At present, the synthetic fibers used in the production of geotextile are mainly nylon, polyester, polypropylene, ethylene fiber, they have strong buried resistance, corrosion resistance.

Geotextile is divided into short fiber needled punch geotextile (non-woven fabric, also known as short silk geotextile), long silk needled punch non-woven geotextile (also known as filament geotextile), woven geotextile, composite geotextile (also known as waterproof geotextile), etc.

Characteristics and uses of various geotextiles:

1. Staple fiber needled geotextile, also known as short filament geotextile, has the characteristics of aging relief, filtration, repeated filtration, acid and alkali resistance, wear resistance, good flexibility and easy construction. It can be used for maintenance, filtration, reinforcement of roads, railways, DAMS and hydraulic buildings.

2. Filament needled nonwoven geotextiles, also known as filament geotextiles, is made of polyester chips as raw materials through textile and needled production, in addition to the characteristics of short silk geotextiles, and closed (impervious) function, mainly used for water conservancy, dam, tunnel, landfill protection, impervious.

3. Composite geotextile (also known as waterproof geotextile), in fact, is another name for composite geomembrane, which is mainly made of a layer of geomembrane each bonded to a layer of geotextile (we commonly known as two cloth a film, except for a cloth a film, two cloth two membranes, three cloth two membranes and other multi-cloth multi-membrane can be customized according to customer requirements). Geotextile is mainly to protect the intermediate geomembrane from harm, its anti-seepage effect, generally used for artificial lakes, reservoirs, canals, landscape lake anti-seepage.

4. Woven geotextile is made of polypropylene, propylene vinyl fiber flat yarn as raw material, composed of at least two groups of parallel yarn (or flat yarn), a group along the loom longitudinal (fabric direction of travel) called warp, another group of transverse arrangement called weft. With different knitting equipment and technology will warp and weft woven together woven cloth, according to different construction, the first to use smaller diameter sand or clay leveling base, and then lay geomembrane. Geomembrane do not be too tight, buried in the soil at both ends of the part is corrugated, and finally in the spread of geomembrane with fine sand or clay spread a layer of about 10cm over the layer.

Construction, should try to avoid stones directly hit on the geomembrane, it is best to cover the edge of the protective layer construction.

The application range of geotextiles is very wide, aging problem has been a very important life factor in the application of geotextiles, we need to understand clearly in order to make the application of geotextiles better, so that it is more favored by users.

So at present, the mainland which manufacturers produced geotextile product quality is relatively good? Obviously, it is difficult to find a standard answer to such a question. With the increase of customer orders in customization, geotextile manufacturers need to constantly improve the customization technology, but also need to constantly improve the customization service process, in order to meet the actual needs of customers. Only in this way can the process of expanding sales in the market be more relaxed and easy.
