Customer background

Customer Background

A road-construction company in Inner Mongolia was awarded the local expressway anti-seepage works and needed a high-uniformity geotextile line for high-grade impermeable layers.

The challenge

The Customer’s Production Challenges

Only challenges supported by the original project material are included here.

01

Thickness uniformity

High-grade impermeable layers require tightly controlled thickness uniformity.

02

High daily output

The project required high continuous daily output.

03

Reliable delivery quality

Consistent first-pass quality was needed for engineering acceptance.

ZHOU JI solution

A 6,500 mm Geotextile Line for High-Grade Impermeable Layers

ZHOU JI supplied a 6,500 mm-wide geotextile needle punching line featuring cross-lapping and multi-zone needling. The resulting fabric achieves thickness uniformity CV ≤3%, meeting the stringent requirements of high-grade impermeable layers used in highway anti-seepage works.

01

Fiber Opening

Open PET / PP or recycled fibers for a stable supply.

02

Blending

Even out the fiber composition before carding.

03

Carding

Form a uniform web for wide-width geotextile.

04

Cross-lapping

Build product weight, width and thickness.

05

Multi-Zone Needling

Consolidate the web for high-grade impermeable layers.

06

Winding

Wind the finished geotextile into rolls.
