Intercontinental Nonwoven Machinery

Synthetic Leather Substrate Production Line

ZHOU JI provides complete synthetic leather substrate production lines for needle punched nonwoven base fabrics used in microfiber leather, PU / PVC synthetic leather and artificial leather. The line covers fiber opening, blending, carding, web formation and multi-stage needle punching, configured around the fiber system, substrate weight, working width, apparent density and surface flatness. It can be adapted to island-type and other fine-fiber systems.

Finished Products

The line can produce different nonwoven leather substrates to suit fiber systems, density and downstream leather processing requirements.

Microfiber leather base fabric

Microfiber Leather Base Fabric

Dense needle punched nonwoven base fabric designed for microfiber synthetic leather production.

The substrate provides a stable fiber structure for subsequent impregnation, splitting and finishing processes.

Island-type microfiber leather substrate

Island-Type Microfiber Leather Substrate

Nonwoven substrate made from island-type microfiber systems for high-density microfiber synthetic leather applications.

Multi-stage needling helps build the required three-dimensional fiber structure before downstream processing.

PU and PVC synthetic leather substrate

PU / PVC Synthetic Leather Substrate

Needle punched synthetic leather base fabric for PU or PVC coating, impregnation and other artificial leather manufacturing processes.

Synthetic leather backing fabric

Synthetic Leather Backing Fabric

Nonwoven backing material for synthetic leather products requiring consistent thickness, strength and dimensional stability.

01

Opening & blending

Polyester, island-type microfiber or other fibers are opened and blended for a consistent fiber supply.

02

Carding & web formation

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

03

Multi-stage needle punching

Several needling stages build a dense 3D fiber network; direction, density and intensity are set by substrate requirements.

04

Inspection & winding

The substrate is checked for weight uniformity, thickness and surface, then wound for downstream leather processing.

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

It produces the nonwoven base fabric used before coating, impregnation and other synthetic leather processes. Main stages include fiber opening, blending, carding, web formation and multi-stage needle punching.

A dense nonwoven substrate made from fine or microfiber-based fibers. Needle punching forms a three-dimensional fiber network that provides the structure for subsequent microfiber leather processing.

A single needling stage may not provide enough entanglement for a dense substrate. Multi-stage needling gradually reinforces the web and controls density, strength, thickness and surface condition.

Opposed or staggered needling entangles fibers from different directions to develop a denser, more stable 3D structure — suitable for microfiber base fabric requiring high structural stability.

Yes. The process can be configured for island-type microfiber systems used in high-density microfiber synthetic leather substrate production, depending on fiber characteristics and required structure.

Basis-weight uniformity, thickness consistency, surface flatness, apparent density, fiber entanglement and structural stability — influenced by fiber preparation, carding, web formation and needle punching settings.
