Shanghai Yingfan Engineering Material Co., Ltd. is a comprehensive geosynthetics supplier in China. Our products can be widely used in a lot of civil engineering projects such as water conservancy, hazardous waste landfill, tailing waste containment, airport construction, high speed railway construction, etc.
PP filament nonwoven geotextile is spunbonded needle punched geotextile. It is produced by Italy and Germany imported advanced equipment. With the advanced spinning equipment, the filament fineness can reach more than 11 dtex, and strength can reach more than 3.5g/d. Its performance is far higher than our national standard GB/T17639-2008.
In virtue of the superior physical properties and good chemical stability of PP geotextile, it can be applied to any geotechnical engineering environment, especially the alkali environment. Polyester geotextile will be gradually decomposed and strength decrease sharply under alkaline conditions, so using polyester geotextile will cause safety risks of the project.
PP filament nonwoven geotextile has the following functions showed in the drawing:

PP Filament Nonwoven Geotextile VS PET filament Nonwoven Geotextile
1. Lower density than PET geotextile with larger area based on the same strength.
2. Better chemical resistance than PET geotextile.
3. Higher abrasion resistance than PET geotextile.
4. More hydrophobe than PET geotextile.
5. Higher strength than PET geotextile based on same unit weight.
PP filament nonwoven geotextile properties far exceed our national standard GB/T 17639-2008, its technical properties are showed as below:
