Generally, other synthetic leathers other than genuine leather such as PVC and PU leather are collectively referred to as artificial leather or imitation leather. There are two common types of people looking for leather: PVC and PU. They are both polychlorinated and vinyl (a kind of plastic), but the manufacturing processes of these two products are very different.
In the process of manufacturing PVC leather, the plastic particles should be hot-melted and stirred into a paste and uniformly coated on the T/C knitted fabric base with a certain thickness, and then put into a foaming furnace for foaming, so that It has a softness that can adapt to the production of various products and different requirements, and the surface treatment (dyeing, embossing, polishing, matting, grinding and fluffing, etc. are mainly carried out in accordance with specific product requirements) when it is released.
The manufacturing process of PU leather is more complicated than that of PVC leather. Since the base fabric of PU is a canvas PU material with good tensile strength, in addition to being coated on the top of the base fabric, the base fabric can also be included in the middle, so that the The existence of the bottom cloth cannot be seen from outside. The physical properties of PU leather are better than that of PVC leather. The pattern of PVC leather is made by hot pressing with steel pattern rollers; the pattern of PU leather is first hot pressed on semi-finished leather with a pattern paper.
In fact, our hardcover notebook covers also use PU leather. High-quality PU can also enhance the texture and value of notebooks. It is also a good choice for gifts.
