Shanghai Yingfan Engineering Material Co., Ltd. is specialized in producing and exporting of PET short filament nonwoven geotextile. PET short filament geotextile is maybe the most widely used nonwoven geotextile in civil engineering around the world because of its good performance and low cost.

PET Short Filament Nonwoven Geotextile Introduction

PET short filament geotextile is manufactured under advanced production and quality‑control system to achieve highly uniform, consistent needle‑punched non‑woven geotextile. Yingfan adopts strict fiber selection, inline quality monitoring and in‑house laboratory testing, to guarantee every delivered roll meets customer and project‑specific specifications.

PET raw material delivers good UV‑resistance and chemical‑resistance performance. It is an eco‑friendly geotechnical construction material.

Functions

PET short filament geotextile core functions: separation, filtration, drainage and reinforcement.

Features

1. Superior water permeability & good filtrability

2. Good deformation adaptability, corrosion‑resistant and anti‑aging

3. Reliable water‑diversion performance, forms drainage channels to discharge excess liquid and gas

4. Maintains high permeability under soil‑water loading pressure

5. Efficiently distributes and relieves concentrated stress to avoid soil damage

6. Blocks intermixing between stone layers, soil and concrete

7. Acid‑alkali resistant, anti‑oxidation, non‑corroded by biology, made of polyester/PP chemical fiber

8. Light‑weight, easy‑handling, convenient construction, shortens construction period and improves economic benefit

9. Improves soil tensile strength and anti‑deformation performance, stabilizes building structure and optimizes soil condition

Application

PET short‑filament non‑woven geotextile is designed for filtration, soil stabilization, separation, drainage, gas transmission, cushion and liner‑protection purposes:

1. Reinforcement for retaining‑wall backfill

2. Soft‑road strengthening and pavement crack‑treatment

3. Slope stabilization & soil reinforcement, prevent soil‑water loss and frost damage

4. Isolation layer for artificial backfill, stone‑soil foundation and different frozen‑soil layers

5. Filtration layer for drainage pipes and gravel sub‑drains

6. Vertical & horizontal drainage; buried for releasing soil air pressure

7. Soft‑foundation reinforcement for roads, railways, embankments and airport projects
