How Is Pu Leather Made?

The main component of PU leather is polyurethane, with a plasticizer and UV light stabilizer to provide resistance to sunlight. However, the production process of this type of leather is mind-blowing and simple to understand. First, a base fabric is chosen considering the end product. For example, if the leather is to be used for manufacturing furniture, the thick fabric will be used to keep the robustness that it requires. If the leather is for something like leather bags or wallets, a thinner and lighter fabric will be used. Technically, leather is built on this fabric. Then machines will apply a plastic coating on the base fabric. The plastic coat consists of polyurethane, plasticizer, and other materials. Next, a second coat of plastic is applied to the first coat. The second coat covers any imperfections that were left by the first coat. Color dyes are coated on the base fabric through the second coat. Finally, the double-coated base fabric is pressed with release papers. The release paper is a thick and heavy paper with leathery patterns carved into it. After the manufacturing process, PU leather sheets are cut and shaped into their value-added end product.
