AI Technical Summary
Technical Problem
Leather produced by existing tanning processes has slightly poor flexural resistance during use, obvious wrinkles on the surface, and low quality and grade.
Method used
A multi-layer coating process is employed, including pretreatment, sealing, base coat, intermediate coat, top coat, and hand-feel layer treatment. A specific resin and emulsion composition is used to form a uniform and flexible coating on the leather surface through high-pressure airless spraying technology.
Benefits of technology
It improves the leather's resistance to bending, gives it a smooth and even appearance, and enhances the quality and grade of the finished leather.
