Chaîne de production de géotextiles

ZHOU JI provides complete geotextile production lines for infrastructure, road, railway, drainage and environmental engineering. The line combines fiber opening, blending, carding, crosslapping and needle punching to produce strong, uniform nonwoven geotextile, configured around raw material, target GSM, working width and output. Suitable for PET / polyester, PP / polypropylene and recycled PET fibers.

Geotextile Production Line process validation

Opening & blending

PET, PP or recycled polyester fibers are opened and evenly blended for a stable fiber supply.

Carding & crosslapping

The fibers are carded into a uniform web and crosslapped to build the required weight, width and thickness.

Needle punching

Repeated needle penetration mechanically entangles the fibers; needling is set by weight, thickness and strength.

Finishing & winding

Optional heat setting or coating is added, then the geotextile is wound into rolls for transport or processing.

FAQ

Common questions before requesting a line proposal.

The answers below help buyers prepare the right project information before discussing equipment configuration, factory layout and delivery support.

What machines are included in a geotextile production line?

A typical line includes a bale opener, fiber opener, big hopper blender, pneumatic feeder, carding machine, cross lapper, batt feeder, geotextile needle punching machines and winding equipment. Heat setting and coating can be added.

Can the line produce both PET and PP geotextile?

Yes. The same line can be configured as a PET geotextile production line or a polypropylene geotextile production line by adjusting fiber preparation, web formation and needle punching parameters.

Can recycled PET be used for geotextile production?

Yes. A recycled PET geotextile line can be configured according to the recycled fiber characteristics, target GSM, working width and finished product requirements.

What GSM can the line produce?

The reference configuration covers approximately 100–2000 gsm. The final range depends on raw material, line speed, web formation and needle punching configuration.

What is the maximum working width?

The reference line can be configured for working widths up to 8,500 mm, depending on the selected carding, crosslapping, needle punching and downstream equipment.

What affects geotextile production line cost?

Cost mainly depends on working width, target GSM, required output, raw material, number and type of needle punching machines, automation level and downstream finishing.
