How is PU Leather Made?
☆ Dry and Wet Process
It is made using two methods: dry and wet processes; each has its own steps and outcomes.
▶ Dry Process
- Coating on Release Paper
Polyurethane resin slurry is applied to release paper, usually in one or two layers.
Baked in an oven to remove solvents and to form a polyurethane film.
- Adhesive Application
Adhesive is applied to the dried polyurethane film.
The film is attached to a base cloth and solidified before the release paper is removed.
- Bonding with Fabric
A fabric base, like polyester, cotton, rayon, or nylon, supports a polyurethane film. It adds strength and durability.
- Drying and Curing
Coated material is dried to remove moisture.
Curing process in a controlled environment for 36 to 48 hours.
▶ Wet Process
1. Coating on Nonwoven Fabric：Polyurethane slurry is extruded onto nonwoven fabric. Fabric is immersed in a bath with DMF (N,N-Dimethylformamide). It causes the polyurethane to gel and form a solid film.
2. Micropores Formation：Micropores form during coagulation from additives and polyurethane shrinkage. They allow air and moisture to flow.
3. Washing and Drying: DMF is removed through washing and then drying to remove any leftover solvents.
4. Surface Coating: The final layer of polyurethane is applied using release paper. Baked in an oven and peeled off, the finished Polyurethane leather is revealed.
☆ Additions for Durability and Style
1.Printing and Texturing: Surface is embossed or printed to mimic a natural leather pattern and style.
2. Surface Treatment: Final adjustments for color and texture for both appearance and usability.
☆ Environmental Impact
- Dry processing produces more exhaust gas but less wastewater.
- Wet processing improves moisture and air permeability with its microporous structure.
