Introduction

Polyester Continuous Filament Non Woven Geotextiles are made from 100% polyester long fibers, formed by the process of needle punching and thermally bounding,as to be protection materials,separator material and filter material etc. The product is mainly white, high tensile strength, corrosion resistance, erosion resistance…etc.The product width from 1m-6m,length 50m-100m,u can customize it.

Properties Of Polyester Continuous Filament Non Woven Geotextile

 *Made by pure long fibers

*Needled homogenously and properly

*Needled number and frequency are adjustable

*Line speed is adjustable

*Fiber length and size(denier/diameter)are adjustable

*Thermal treatment temperature is adjustable

*Thermal treatment roll pressure is adjustable

*Fiber blend and mixing and crimp are adjustable

*Product up to 6m width and 100m length

Advantages Of Polyester Continuous Filament Non Woven Geotextile

*Reduced volume of earthworks and soil transportation

*Straightforward,low-dust installation to speed up progress on site

*Replaces expensive well-graded sand and gravel with less expensive non-graded mix

*Provides long term performance with less clogging and maintenance

*Reduces reflective cracking and subsequently maintenance cost

*Aids in pavement flexibility

*Lower project cost leading from reduced aggregate thickness

*Maintains integrity and increases long term performance of pavement system

*Resistive to alkaline and acidic conditions

*Easy to install

Application Of Polyester Continuous Filament Non Woven Geotextile

*It’s using as reduce settlement of weak soil,stabilization of earth and formation of non-linear local settlements

*It’s used as filtering and bedding material in the coastal structures in order to prevent dislocation and mixing of fine and coarse material due to wave effect

*It must be applied on ready surface tightly and properly in order to assure full surface contact without any flexion

*Protection of waterproofing board on roofs and terraces

*Protection of external insulation board on roofs or terraces

*Protection of liquid waterproofing membrane on roofs or terrace or balconies

*Protection of waterproofing liner as HDPE,LDPE or PVC on water tanks or pools

*Protection of thin screed and topping concrete layer

*It improves resistance to damage coming from puncture and excessive friction loads
