The main component of PU leather fabric is polyurethane (PU). Polyurethane is a polymer compound formed by the reaction of isocyanate groups and hydroxyl groups, which has the characteristics of resistance to bending, softness, strong stretchability, and breathability.
PU leather is widely used in the decoration of luggage, clothing, shoes, vehicles, and furniture. Its advantages include soft gloss, soft feel, strong leather feeling, abrasion resistance, flexure resistance, aging resistance, etc., and it also has the characteristics of good cold resistance, breathability, washability, convenient processing, and low price.
In the production process, the substrate of PU leather is usually non-woven fabric made of synthetic fibers, which has a porous structure similar to the mesh structure of natural leather. This structure makes PU leather similar to natural leather in appearance and physical properties, and has a more vibrant color.
