Composite geotextile, also known as geotextile, which is synthetic fiber through acupuncture or weaving made of permeable geosynthetics. Finished products for the cloth, the general width of 4-6 meters
, The length of 50-100 meters. Geotextile is divided into a geotextile and non-woven geotextile. Geotextile has excellent filtration, isolation, reinforcement protection, high tensile strength, good permeability, high temperature, anti-freeze, anti-aging, corrosion resistance.
Nonwoven composite geotextile
Non-woven geotextile is made of filament or staple fiber through different equipment and process shop in a mesh, after acupuncture and other processes so that different fibers intertwined with each other, tangled to the fabric of the normalization, so that the fabric soft, Plump, thick, stiff, in order to achieve different thickness to meet the requirements of use, non-woven geotextile has a good fabric gap, a good attachment from the fiber due to a certain degree of anti-tearing anti- Good deformation adaptability, but also has a good flat drainage capacity, the surface of a soft multi-gap has a good coefficient of friction can increase the adhesion of soil particles, etc., can prevent small particles by preventing the loss of particulate matter at the same time ruled out the excess water, Soft surface has a very good protection. According to the length of the silk is divided into filament non-woven geotextile or short silk non-woven geotextile. They can play a very good filter, isolation, reinforcement, protection and other effects, is a widely used geosynthetics. Filament tensile strength higher than the short wire, according to the specific requirements of choice.
Woven composite geotextile (reinforced geotextile)
There are at least two sets of parallel yarns (or flat yarn), a group of looms along the loom (the direction of fabric travel) called warp yarn, another group of horizontal arrangement called weft. With different preparation of weaving equipment and technology will be woven and weft yarn woven together woven fabric, according to the different use of the range of woven into a different thickness and density, generally have a thin geotextile longitudinal and horizontal have a very strong resistance Tensile strength (longitude than latitude), with good stability. There are two types of reinforced geotextile and reinforced geotextile according to the weaving process and the use of latitude and longitude. The tensile strength of the reinforced geotextile is much greater than that of the ordinary geotextile. There are general application of geotextile and geotextile project reinforcement, the main function is enhanced reinforcement, with a plane isolation and protection functions, do not have the plane drainage function can be selected according to the specific purpose of use.
