Continuous Filament Spunbonded Nonwoven Geotextile

Made from virgin PET(polyester)chips. The continuous filament is extruded from PET chip by machine directly through spunbond process, then punched together to get stable 3D and high strength fabric. So, it has high strength, good creep property and excellent erosion resistance, aging-resistance and heat resistance.

Specification

Weight: 100g/m2 – 800g/m2

Width: 4-7m; Length: 50-200m(as requested)
