PU is polyurethane, and PU leather is leather with polyurethane components. Many garment manufacturers widely use PU leather to produce garments, commonly known as imitation leather garments. It is also widely used in life, especially in making purses.
PU leather is generally the second layer of leather with cowhide on the reverse side, and the surface is coated with a layer of PU resin, so it is also called coated cowhide. With the change of technology, it can also be made into various grades of products, such as imported two-layer cowhide, which is a high-grade leather with unique technology, stable quality and novel varieties.
Compared with real leather, PU leather is lighter in weight, waterproof, less prone to swelling or deformation after water absorption, environmentally friendly, light in smell, easy to handle, and more patterns can be extruded on the surface. The bag made of PU leather is not only beautiful in appearance, easy to take, but also low in price.
Characteristics of PU leather:
PVC (imitation leather): It is rarely used on sofas, or only used on ultra-low-end sofas. PU (imitation leather): it is usually used for non-contact surfaces of offices and leather sofas.
Ultrafine leather and technical cloth will be used as contact fabrics for sofas. Polyurethane pays more attention to skin feeling, while technical cloth pays more attention to hand feeling. Many technological fabrics produced in reality are indeed fabric sensitive, which may be the real reason why technological fabrics are not called technological leather.
After cutting on the basis of superfine fibers, many fibers stand upright and can be touched by hands. Its matrix is very similar to dermis, so it can also be used as a control to distinguish whether it is polyurethane or PU.
