Reinforced high strength spun polyester filament woven geotextile
Short Description:
Filament woven geotextile is a kind of high strength geomaterial made from synthetic materials such as polyester or polypropylene after processing. It has excellent physical properties such as tensile resistance, tear resistance and puncture resistance, and can be used in land regulation, seepage prevention, corrosion prevention and other fields.
Products Description
Filament woven geotextile is a classification of geotextile, it is high strength industrial synthetic fiber as raw materials, by weaving process production, is a kind of textile mainly used in civil engineering. In recent years, with the acceleration of infrastructure construction around the country, the demand for filament woven geotextiles is also increasing, and has great market demand potential. Especially in some large-scale river management and transformation, water conservancy construction, highway and bridge, railway construction, airport wharf and other engineering fields, has a wide range of applications.
Specification
Nominal breaking strength in MD (kN/m): 35, 50, 65,8 0, 100, 120, 140, 160, 180, 200, 250, width within 6m.
Property
1. High strength, low deformation.
2. Durability: steady property, not easy to resolved, air slaked and can keep the original property long term.
3. Anti-erosion: anti-acid, anti-alkali, resists insects and mould.
4. Permeability: could control the sieve size to retain certain permeability.
Application
It is widely used in river, coast, harbor, highway, railway, wharf, tunnel, bridge and other geotechnical engineering. It could meet all kinds of geotechnical projects needs such as filtration,separation,reinforcement, protection and so on.
