PE Geotextile Production Line

PE geotextiles produced by this line are widely used in:

Road & railway construction – separation and stabilization of subgrades, preventing aggregate mixing with soil.
Landfill liners & covers – drainage and protection layers beneath geomembranes.
Erosion control – on slopes, riverbanks, and coastal revetments.
Drainage systems – behind retaining walls or under pavements.
Mining & tailings ponds – as a permeable barrier for liquid-solid separation.

Real-world case
A highway expansion project in Southeast Asia used the JWS150/150-6400 model to produce 6,000 mm wide, 2.0 mm thick PE geotextile. The dual-extruder setup delivered 1,350 kg/h, allowing the contractor to cover 12,000 m² per shift. The wide width reduced on-site seams by 40%, accelerating installation and lowering labor costs.

Every production batch follows a strict QC protocol to meet international standards (e.g., ASTM, ISO, EN).

1. In-process monitoring
Melt temperature & pressure sensors at each extruder (JWS150) – ensure stable output within ±2°C.
Ultrasonic thickness gauge scanning across the full width (2,000–8,000 mm) every 5 seconds. Tolerance: ±0.05 mm.
Online width measurement using laser sensors – automatically adjusts spreading rollers.

2. Laboratory testing (per roll)

3. Roll finish inspection
Visual check for pinholes, wrinkles, or contamination.
Core hardness and edge straightness measured with a go/no-go gauge.
Each roll is labeled with model, width, thickness, lot number, and test report QR code.

Real-world example
A Chilean mining company required 1.5 mm PE geotextile for tailings pond lining. The JWS150/150-8500 line produced 8,000 mm rolls. Third-party lab results showed puncture resistance of 620 N and permittivity of 1.8 sec⁻¹ – exceeding project specs. Zero defects were found in 150 consecutive rolls.

Q1: What is the difference between single and dual extruder models?
A: Single extruder (JWS150-2400) uses one JWS150 screw, max output 600–700 kg/h, width 2,000 mm. Dual extruder models (JWS150+JWS150) run two extruders feeding a single wide die, delivering 1,200–1,450 kg/h for widths from 4,000 to 8,000 mm. Dual configuration also provides redundancy – if one extruder needs maintenance, the other can continue at reduced output.

Q2: Can I produce nonwoven geotextile on this line?
A: No – this line is for solid PE sheets (smooth or textured). For nonwoven (needle-punched) geotextiles, you would need a staple fiber or spunbond line. The JWS series is ideal for geomembrane backing, drainage geocomposites, and impermeable liners.

Q3: How do I change thickness during production?
A: Adjust the die lip gap and take-up speed. Thinner sheets (0.5 mm) require faster haul-off; thicker sheets (3.0 mm) use slower speed. The transition takes about 10–15 minutes, and the online thickness gauge confirms uniformity before switching to new rolls.

Q4: What is the typical roll length for 8,000 mm width?
A: Limited by roll weight for handling. For 2.0 mm thickness, a full roll (approx. 800 kg) gives about 65 linear meters. For 0.8 mm, same weight yields ~160 meters. We can supply custom lengths upon request.

Q5: Do you provide installation training?
A: Yes – our engineers supervise first-run commissioning at your site. We also provide manuals and video tutorials. Remote support is available 24/7 via video call.

Q6: How does the production line handle recycled PE?
A: The JWS150 extruders have a high-torque gearbox and wear-resistant screw coating (bimetal). They can process up to 30% post-industrial recycled PE (clean, dried, and reground) without significant output loss. For higher recycle ratios, we recommend adding a melt filter and degassing unit.

Q7: What is the power consumption per kg?
A: Approximately 0.25–0.30 kWh per kg for the dual extruder models at full capacity. The single extruder model consumes about 0.28–0.32 kWh/kg. Energy recovery systems (optional) can reduce this by 15%.
