I. Performance and Application of Polyurethane Polyurethane is a kind of synthetic leather with high-grade leather inside, which has better performance and wear resistance than other leathers. Polyurethane is added to it to improve the characteristics of leather and maintain the particularly good properties of leather. Because it is superfine fiber, this kind of leather is very soft, very soft to the touch and very shiny on the surface.
At present, this kind of superfine fiber is widely used. The leather is better than the real leather, and the surface layer is particularly stable. If further improved, it can replace dermis. In addition to clothes, it is also used in sofas, sachets, gloves, car cushions and cell phone holsters, and microfibers become daily necessities.
Second, the difference between polyurethane and dermis Although polyurethane is catching up with dermis, there is still a gap between the two. Polyurethane is close to dermis. If you look closely, you will find that the lines of dermis are natural and the pores are clear, while the lines of polyurethane are not so clear, and the pores are unnatural but neat. Almost all polyurethane gives people the feeling of plastic.
The weight of leather is different from that of polyurethane. Leather is heavier than polyurethane. Under the same conditions, polyurethane is lighter than real leather. A dress is made of the same material. After weighing, you can see that polyurethane is lighter than real leather. When choosing whether it is genuine leather, you can feel whether it is thick or not by touching it.
Smell is also the best way to tell whether it is genuine leather. Polyurethane is made artificially, and there are many chemical components in it, so it will have a pungent taste, and maybe a plastic taste. Most of the dermis is made of animal skin, so it is necessary to remove the smell of animals when making it, and some heavy metals will be added to reconcile this smell.
