The Production Process Steps Of PU Leather

Slurry preparation: Mix polyurethane resin with other additives to form a uniform slurry.
Coating: Apply the prepared slurry onto a substrate, such as non-woven fabric or lint free fabric.
Solidification: The coated substrate undergoes solidification treatment to cure the polyurethane.
Washing and drying: After solidification, the substrate is washed with water to remove residual solvents and impurities, and then dried.
Surface treatment: Embossing, grinding, and other treatments are applied to the leather surface as needed to enhance its aesthetics and functionality
