geotextile short fiber cloth non woven for construction

Geotextile short fiber cloth non woven 

Geotextiles are permeable nonwoven fabrics used to separate,filter,reinforce, protect or drain.Geotextiles allow filtration or separation of granular layers in roads and rail applications,used to protect membranes in landfill applications,used in coastal defence applications and used in landscaping to protect surfaces and structures from weeds and root growth.

Geotextiles are available as woven and non-woven .As liner protection, against physical damage, the non wovens are normally the answer.They are made up of fibers of polyester or polypropylene in random directions and punched together by needles during the manufacturing process.Geotextiles are normally used to separate layers like clay and drainage and to protect liner from damage.

Features:

1, tensile and tearing resistance, bursting resistance, resistance to puncture, such as high mechanical strength, is equally grams weighs more than doubling of staple fiber geotextile, especially bursting resistance, strength reached more than 2200 Newton, in the stone slope protection, can effectively prevent irregular stones on the impact of the cloth;
2, good extension performance, stress dispersion and transmission is fast, make the uniformly distributed load;
3, the friction coefficient is big, not easy to slip when construction;
4, good chemical resistance;
5, corrosion resistance;
6, ageing resistance, embedded laid, the service life of more than 50 years;
7, heat resistant, cold resistant performance is good, can withstand 200 ~ 30 ℃ temperature difference and the quality is not affected;

Applications:

Filtration

It can be the filtration layer of the dykes, river canal, seacoast, concrete slope, retaining walls. At the same time of preventing the clay granule from passing, it allows the water and the gas pass through freely.

Separation

The isolation of the railway dregs and the roadbed, roadbed and the soft base, surface of the airdrome and parking lot and the groundsill, different dam materials. It isolates the soil and the gravel of two kinds different

granule pathway from the groundsill or other buildings.

Reinforcement

The highway, railway, soil-stone dam, breakwater, airport, backfill soil of retaining wall, slope protection, etc in which distributes the earth stress, prevents the side-displacement of the earth body and improves the earthbody stability.

Protection

It prevents the bank from being washed out, protects the bank and the

bottom, prevents the water and soil from being washed away.

So nonwoven fabric can be used in almost any stabilization,separation or cushioning application,they are most commonly used in areas that also require filatration.The non woven design of the material provides a higher rate of flow through,making it easier for water to pass through the material.Some commen uses of the material includes the following:

     * Road stabilization applications

     *Roofs

     *Civil applications

     *Railway work

     *Landfill lining

     *Trenches

     *Dams

     *Filtration under rip rap and rocks

     *Environmental applications
