Product introduction of polyester short fiber needle punched non-woven geotextile:

The staple nonwoven geotextile is carding the synthetic fiber into net after opening , on the web under the repeated use puncture needle to make fiber entanglement fixation into cloth. The thickness of the product is more than 1mm, high porosity, high permeability, filtration drainage performance and application in water conservancy and highway engineering is very wide. It can also be combined with the geomembrane to form a composite material, which can provide reinforcement and protection to the membrane.

Product features of polyester short fiber needle punched non-woven geotextile:

1. high permeability,and it still can maintain good water permeability under the pressure of earth;

2. corrosion resistance, with polypropylene or polyester fiber as raw material, acid and alkali resistance, no corrosion, no moth, antioxidant;

3. simple construction, light weight, easy to use.

Application scope of polyester short fiber needle punched non-woven geotextile:

1. with different physical properties of building materials for isolation, so that two or more materials between the loss, not mixed, to maintain the overall structure and function of the material, so that the structure of the load bearing capacity;

2. when the water from the soil into the fine coarse material layer, good air permeability and water permeability of geotextile by acupuncture, the water flow passes through effective interception of soil grain, fine sand, small stones and so on, in order to maintain the stability of soil and water engineering;

3. the concentration of stress diffusion, transfer or decomposition, to prevent the soil from the external force and destruction;

4. preserve highway subgrade pavement’s health;

5. railway subgrade, dam, reclamation engineering filtration, isolation, drainage, maintenance.
