The Future of Soil Stabilization

Quality Control

Ensure the seepage prevention system achieves "zero leakage" and long-term stability.

Geotextile Production Process

Generation process

1

Raw Material Preparation and Drying

High-quality polyester (PET) chips are primarily used. Vacuum drying prevents hydrolysis during high-temperature melting, ensuring the mechanical strength of the filaments.

Ingredients and extrusion SOP

2

Melt Extrusion Screw Extruder

The dried chips enter the screw extruder, where high temperature and mechanical shearing melt the solid chips into a uniform polymer melt.

Precision stamping SOP

3

Spinning and Drawing

This is the key step that distinguishes filament geotextiles from staple filament geotextiles: spinning.

Lateral stretching SOP

Longitudinal stretching SOP

4

Yarn Spinning and Web Formation

The drawn filaments vibrate and disperse under the action of airflow.

Roll forming and testing SOP

5

Mechanical Reinforcement (Needle Punching)

Pre-needle punching and main needle punching: The loose fiber web enters the needle punching machine, causing the fibers to intertwine and lock together.

Roll forming and testing SOP

6

Edge Trimming, Rolling, and Inspection

Heat Setting/Singeing (Optional): Depending on customer requirements, surface heat rolling or singeing may be performed to improve fabric smoothness or control thickness.
