PP (Polypropylene) Filament Nonwoven Geotextile Introduction

PP filament non‑woven geotextile is spun‑bonded needle‑punched geotextile, manufactured with advanced imported production lines from Italy and Germany. Spinning equipment delivers filament fineness over 11 dtex and single‑filament strength above 3.5 g/d. Its performance exceeds Chinese national standard GB/T17639‑2008.

Benefiting from excellent physical properties and stable chemical performance, PP geotextile fits various geotechnical environments, especially alkaline working conditions. Under alkaline surroundings, polyester geotextile will degrade gradually with sharp strength loss and bring hidden risks to projects.

Main Functions

Core functions: separation, filtration, drainage, reinforcement, protection.

‑ Separation: isolate different soil‑layer materials to avoid intermixing

‑ Filtration: permit water flow while retaining soil particles

‑ Drainage: collect and discharge excess pore‑water

‑ Reinforcement: improve soil‑base bearing capacity and distribute load

‑ Protection: shield geomembranes and liners against puncture damage

Different application scenarios correspond to primary(X) and secondary(O) functions:

‑ Paved / unpaved roads & soft subgrade: Separation(X), Filtration(X), Reinforcement(X), Protection(O)

‑ Paved / unpaved roads & firm subgrade: Separation(X), Filtration(O), Drainage(O), Reinforcement(O)

‑ Road repaving: Filtration(O), Drainage(O), Reinforcement(X)

‑ Road drainage: Filtration(O), Drainage(X), Reinforcement(O)

‑ Sports fields: Separation(X), Filtration(X)

‑ Erosion‑control & hydraulic projects: Filtration(O), Reinforcement(X)

‑ Railways: Separation(X), Reinforcement(X)

‑ Geomembrane containment projects: Separation(O), Filtration(X), Drainage(O), Reinforcement(O), Protection(X), Waterproofing(O)

‑ Embankments: Separation(X), Filtration(X), Reinforcement(X), Protection(O)

‑ Retaining walls: Drainage(O), Reinforcement(X), Protection(X)

‑ Tunnels: Drainage(O), Protection(X)

Application

PP filament non‑woven geotextile is widely used in highway, high‑speed railway, airport, seaport, landfill, tailings dam, fly‑ash landfill, ash‑dam projects, artificial wetland, river‑lake regulation, reservoir, canal, land reclamation, sewage‑treatment works and other geotechnical projects. Especially suitable for alkaline‑environment projects such as heap‑leaching ponds, landfills, tailings dams, ash dams, and anti‑seepage / reinforcement works with direct cement‑water contact in hydraulic & transportation constructions.
