The production process of PU (Polyurethane) synthetic leather involves coating a layer of polyurethane on a fabric backing to create a material that looks and feels like genuine leather. Here are the basic steps involved in the production process of PU synthetic leather:
- Pre-treatment: The fabric backing is pre-treated to remove any dirt, oil, or other impurities that could affect the quality of the final product.
- Coating: A layer of polyurethane is coated onto the fabric backing using a variety of techniques such as roll coating, spray coating, or dip coating. The thickness of the coating can be varied depending on the desired texture and appearance of the final product.
- Drying: The coated fabric is then dried in an oven or using other methods such as hot air, infrared, or microwave radiation.
- Embossing: The dried PU synthetic leather can be embossed with a variety of patterns and textures to create a more realistic look and feel.
- Finishing: The synthetic leather is then finished with additional coatings to improve its durability, water resistance, and other properties. Finishing can also include treatments such as dyeing, printing, and polishing.
Overall, the production process of PU synthetic leather is relatively straightforward and can be customized to create a wide variety of textures, colors, and patterns. The result is a material that looks and feels like genuine leather but is more affordable and environmentally friendly.
