Geotextiles, also known as a geotextile, which is made by acupuncture or woven from synthetic fibers permeable geosynthetics. Finished for cloth-like, the general width of 4-6 m, a length of 50-100 m. The Geotextiles into textile geotextiles and nonwoven geotextiles. Geotextile with excellent filter, isolation, reinforced protective effect, high tensile strength, good permeability, high temperature, anti-freeze, anti-aging, corrosion-resistant. 
 Non-woven geotextile 
 The non-woven geotextile is different equipment and process layout of the filament or staple fiber into a network, and after acupuncture and other technology to allow different fiber intertwined with each other tangles solid fabric normalized, so that the fabric is soft, plump, thick, stiff, in order to achieve different thickness to meet the requirements of non-woven geotextile fabric clearance, good adhesion from the fiber soft tear impermeable membrane force at the same time have a very good deformation ability to adapt at the same time has a very good plane drainage capability, soft surface multi-gap a good coefficient of friction can increase the adhesion of soil particles and other, to prevent fine particles by preventing the loss of particles at the same time ruled out the excess water, surface soft to have a good ability to protect. According to the length of wire into the filament non-woven geotextile or short-filament non-woven geotextile. They can play a very good filtering, isolation, reinforced protective effect, is a widely used geosynthetics. Filament tensile strength higher than a short wire, can be selected according to the specific requirements. 
 Woven geotextile fabric (reinforced geotextile) 
 Spinning geotextile loom is at least two sets of parallel yarn (or flat yarn) composed of a group along the longitudinal direction) on (the fabric moving said warp, another set of horizontal arrangement known as the weft. Preparation of weaving equipment and processes will be interwoven with the warp and weft woven into the cloth-like, depending on the use of weaving into a different thickness and density, usually spun geotextile thin aspect to have a very strong anti- tensile strength (greater than the longitude-latitude), with good stability. Spinning geotextile fabric weaving and use of latitude and longitude are divided into reinforced geotextile and reinforced geotextile two categories, reinforced geotextile warp tensile strength far greater than ordinary geotextile. The spinning geotextile general practical application of geotechnical engineering projects of the reinforced enhanced primary function is to reinforce enhanced with the plane isolation and protection features, and do not have the flat drainage function can be selected depending on the purpose.
