PVC Artificial Leather, Microfiber Leather, And Real Leather Are Related

Take a look at the comparison of different leather materials. The microfiber leather is mainly composed of a base layer made of ultrafine fiber non-woven fabric impregnated with polyurethane resin and a dry-coated polyurethane surface layer. Because the microfiber non-woven fabric itself has a large porosity, it still retains a certain porosity after being impregnated with polyurethane. It can not only achieve the leather effect in appearance, but also close to leather in structure. It has better riding comfort than PVC leather and is equivalent to leather. The dermis is made of raw animal skin, and there is also a porous structure inside, and the dermis material has good air permeability.
Covering materials such as PVC leather, PVC wear-resistant leather, perforated PVC leather, microfiber leather, perforated microfiber and genuine leather are commonly used for seat covering leather. The difference in mechanical properties between PVC leather and PVC wear-resistant leather is relatively small. Because the formulas of the two materials are roughly similar, only the formula of the PVC leather surface layer is slightly different from that of the surface layer. The mechanical properties mainly depend on the performance of the fabric backing; the tensile strength and tear strength of the PVC wear-resistant leather are severely reduced after perforation; The mechanical properties of microfiber leather are better than real leather in all aspects, and the strength is attenuated after perforation, but still maintains a higher value. "Gluing" each other, punching will not damage the microstructure, so the strength and strength values after punching are higher.
The abrasion resistance of genuine leather, microfiber leather and PVC wear-resistant leather is basically the same, and the three are significantly better than PVC leather. Polyurethane coatings on the surface of real leather and microfiber leather materials are all attached to the substrate with a network cross-linked structure, which is beneficial to improve the wear resistance of the coating. Compared with PVC leather, the surface paint layer of PVC leather contains abrasion resistance. Silicone additives, the PVC dense layer formula contains a higher degree of polymerization of PVC powder resin, so the wear resistance is significantly better than that of PVC leather.
As a new type of material, microfiber leather has excellent mechanical properties, color fastness, environmental protection, and cost-effectiveness. Microfiber leather also has strong abrasion resistance and can still maintain a high Tensile strength, so it can give the stylist more styling design choices. The application prospect of microfiber leather in car seats is broad. Even with the development of interior design and material technology progress, the price of microfiber leather will drop, which will bring new growth points for its applications, such as door guards. Parts such as visor, sun visor, steering wheel and roof may be applied to microfiber leather materials in a large area.
