The difference between the geotechnical membrane and the earthwork cloth?

The geotechnical fabric, also known as the earth fabric, is made of synthetic fibers that are made of permeable synthetic material through a needle or needle. Finished cloth, the general width of 4-6 meters, length of 50-100 meters. The geotechnical cloth is divided into a textile and nonwoven fabric. The geotechnical fabric has excellent filtration, drainage, isolation, reinforcement, seepage prevention and protection, and has the characteristics of light weight, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance.
In the field of geotechnical membrane construction, the plastic film is used as the impervious material, and the composite of the non-woven fabric is made up of the soil. At present, the domestic and foreign anti seepage application of plastic film, mainly polyvinyl chloride (PVC) and polyethylene (PE) and EVA (ethylene / vinyl acetate copolymer), they are a kind of polymer chemistry of flexible material, a smaller proportion, extending strong, to adapt to the deformation of high ability, corrosion resistance, low temperature resistance, frost resistance is good. The main mechanism is conducive to the stability of composite geomembrane and a protective layer to plastic film is not permeable partition dam water leakage passage, to the greater tensile strength and elongation under pressure and adapt to the deformation of the dam; and non-woven fabric is also a polymer short chemical fiber material, formed by acupuncture or thermally bonded, has higher tensile strength and elongation, combined with plastic film, not only increases the tensile strength of plastic film and anti puncture capability and due to the non-woven surface roughness, increasing the coefficient of friction of the contact surface. At the same time, they have good resistance to bacteria and chemical action, and not afraid of acid, alkali and
