PP Filament Nonwoven Geotextile

PP (Polypropylene) Filament Nonwoven Geotextile is a durable, permeable fabric made from continuous polypropylene fibers, needle-punched to form strong, interlocked filaments, providing excellent filtration, separation, stabilization, and reinforcement in civil engineering for roads, railways, landfills, and drainage, due to its high tensile strength, chemical resistance, and good water flow.

Key Characteristics

Material: 100% Polypropylene (PP) continuous filaments.

Manufacturing: Created by needle-punching, which interlocks the continuous filaments into a strong, felt-like fabric.

Properties: High strength, good elongation, excellent water permeability, chemical resistance (acids/alkalis), UV resistance (with additives), and resistance to microbes.

Types: Can be staple fiber or continuous filament, with variations like thermal bonding and UV treatment available.
Primary Functions

Filtration: Allows water to pass while retaining soil fines, ideal for drains and pipe wraps.

Separation: Prevents mixing of different soil layers (e.g., gravel from subgrade).

Reinforcement: Improves soil stability and load-bearing capacity, like in retaining walls.

Protection: Shields underlying geomembranes and other structures from damage.

Drainage: Facilitates liquid or gas flow within the soil.

Common Applications

Road & Railway Construction (stabilization, sub-base separation)

Landfills (liner protection, gas venting)

Dams & Embankments

Erosion Control & Slope Protection

Trench & Pipe Drainage Systems

FAQ

Q: What happens if the product is damaged during transportation?

A: We take the following measures to reduce risk: Export-grade packaging + pallet securing; Taking photos to confirm packaging condition before shipment; Arranging third-party pre-shipment inspection (SGS, etc.).

Q: What trade terms and payment methods do you accept?

A: Trade Terms: FOB (major ports such as Qingdao/Shanghai/Tianjin), CIF, and CFR are all acceptable. Payment Method: T/T wire transfer (usually 30% deposit + 70% balance upon receipt of copy of bill of lading), details negotiable.

Q: Can you provide samples?

A: Yes. We provide free samples (small size), with shipping costs borne by the buyer. For pre-production samples before large-volume orders, a sample fee is required, which will be refunded upon placing a formal order. Samples usually come with corresponding test reports for customer verification.

Q: What are the production cycle and delivery time?

A: Standard products are typically produced and shipped within 10-20 business days after order confirmation. This depends on: product type and quantity; whether customized specifications are required; and we recommend informing us of your target delivery date in advance so that we can arrange production and booking accordingly.

Q: How should the product be packaged? Is it suitable for sea freight?

A: All products use export-grade packaging: Geotextile/Geomembrane: Roll packaging, with an outer PE film or woven fabric protective layer, suitable for container loading. Geocells: Can be folded into rolls to save on shipping costs. Drainage Boards: Flat or roll packaging, depending on order quantity. Packaging design fully considers the requirements for moisture and abrasion protection during sea transport. Palletized packaging and customized shipping marks are available.

Q: What is the minimum order quantity (MOQ)?

A: The MOQ varies depending on the product: Geotextile/Geomembrane: There is no strict MOQ for standard specifications, but ordering in rolls is recommended to optimize costs. Geocell: Usually priced per area, small batch orders are acceptable.
