The PU wet process leather production line is the core manufacturing line for producing PU base materials (semi-finished leather). Using the water-based film-forming method, it creates a uniform porous structure within the PU layer. The finished PU base offers breathability close to that of natural leather and serves as the foundation for high-quality PU leather products.
Porous PU Film Formation
Forms a stable and uniform porous structure through the wet-process film-forming method.
Water–DMF Exchange Process
Solidifies PU resin by mutual replacement between water and DMF, creating the PU base layer.
High Breathability Performance
Produces PU base materials with air permeability similar to natural leather.
Semi-Finished Leather Production
Provides a high-quality PU base for subsequent dry-process coating and surface finishing.
In the PU wet process leather production line, a PU resin solution containing DMF is coated onto a substrate and then immersed in a water bath. Through the mutual diffusion and replacement of water and DMF, the PU resin gradually coagulates and solidifies. During this process, a fine and interconnected porous structure is formed inside the PU layer, resulting in a breathable and flexible PU base material.
