Performances & characteristics

High tensile strength, good resistance to ripping, resistance to pushing. It is more than one time of equal weight of flock geotechnical cloth especially resistance to ripping and resisting intensity more than 2200 Newton. Among pieces of stone protection slope, it can protect cloth covered without being assaulted of irregular stones. 
Good performance of extending ,  disperse and transmit quickly of stress, make loading evenly

The coefficient of friction is great, It is difficult to slip while constructing.
Good performance of resistance to chemical attack
Anticorrosive 
Ageing-resistant, the laid of imbedding, service life is more than 50 years
Good performance of heat-resisting and cold-resistant  can stand 200~-30℃ different temperatures' changes but quality is not influenced.

The function of polyester filament geotechnological cloth

Buffer function: It can be made for isolating layer between railway dreg and road bed, airport’s parking layer and groundsill, different dam’s material, can isolate two different grain diameter of grit and plus material or grit and groundsill or other construction materials. 
Filter function: It can be made for filter layer of dyke,  dam ,river, canal and coast or concrete slope, retaining wall, etc., prevent the soil from passing and allow water or  gas to pass freely at the same time.
Protection function:  It can prevent embankment from eroding from wind, wave, tide, rain, be used in the shore protection, bank protection, bottom protection, and prevent soil erosion. 
Strengthen function: It is used in highway, railway, grit dam, defending slope dyke, stadium, retaining wall, backfill soil, slope, distribute the subject stress, increase the mould amount of soil, restrain soil from moving and improve the stability.
