Non woven fabric construction filter 

Product Description

Filament yarn with polyester filament geotextile acupuncture non-woven geotextile, there is a polyester filament geotextile after high-speed needle acupuncture and into cloth products, do not contain chemical additives in the process of needle, also without heat treatment, is environmentally friendly building materials Can replace the traditional engineering materials and construction methods, construction is more secure, and contribute to environmental protection, can be more economic, effective and lasting to solve basic problems in engineering construction.
Polyester filament geotextile the latest national standard GB/T 17639-2008

 

 

 

 

 

 

 

 

 

 

 

 

 

Product Advantage

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

Product Application

1.Water conservancy project and hydropower project
2.Road paving,railway
3.Airport and port
4.River bank protection and tunnel
5.Environmental protection, etc
