MANUFACTURING WORKFLOW
Planning the PU Synthetic Leather Production Process
Dry-process transfer coating, wet DMF coagulation, water-borne mechanical foaming and solvent-free reactive coating or impregnation are separate synthetic-leather routes. Configure substrate handling and downstream treatment for the chosen system.
01
Select the Leather Route
Confirm the substrate, layer construction and whether production uses dry transfer, wet coagulation, water-borne foam or a solvent-free system.
02
Prepare Material and Web
Prepare the route-specific PU material and substrate or release paper, including feeding and web-tension arrangements.
03
Coat or Impregnate
Coordinate coating, mechanical foam application or impregnation with the defined material delivery and layer thickness.
04
Treat the Layer
Use drying and lamination for the selected dry route, coagulation and washing for the wet route, or the specified reactive cure for solvent-free production.
05
Finish the Surface
Arrange separation, drying, finishing and winding appropriate to the selected leather construction.
06
Inspect the Web
Check thickness, surface quality, bonding and agreed mechanical properties, and document route-specific material and process conditions.

Synthetic Leather Processing Routes Selection FAQ
Are dry processing and solvent-free processing the same?
No. A dry route describes the selected coating and drying construction; solvent content depends on the actual resin and adhesive system.
How does water-borne mechanical foaming differ from reactive PU coating?
Mechanical foaming disperses gas into a selected water-borne system. Reactive coating uses separately metered reactive components and its own curing requirements.
Is solvent recovery included in a wet-process package?
Coagulation, washing, recovery and wastewater responsibilities must be explicitly stated in the proposal. A coating or dosing machine listing does not establish the full package.
