Filament woven geotextile
Filament woven geotextiles are composed of two or more than two groups of yarn, tape or other ingredients, usually vertical intersection of woven geotextile. The material is mainly polyester (PET) and polypropylene (PP) of two kinds, with the characteristics of light weight, high strength, less elongation at break, good overall performance, and aging resistance.
SHEEC GROUP is a professional manufacturer in the line of building materials, earthwork products. We always do the best we can.
Usage:
Especially suitable for filtration, separation and drainage of landfills,salt marshes, railway, highway, dams, coastal beaches and other projects.
Properties:
The production line adopts the international advanced technology of the industry and the first time in the application of advanced twin-screw extrusion technology, dual-array spinning system, pipe airflow drafting technique,plate fiber pendulum systems and high-speed needle placed into the fabric production process,18 international and domestic patents,the product has features of high strength, resisitance to aging, acid and abrasion, good flexibility, easy constrction.
Tensile, CBR bursting, tear and piercing strength is one time or more of the value of the short fiber geotextile with the same gram weight.
Greater friction factor and hard to slip during construction.
Better extensibility, faster distribution and transmission of the stress to enable the load equispaced.
Resistance to low and high temperature: subject to temperature changes of -30
°C through +200 °C without impact on its quality.
