Generally, people refer to synthetic leathers other than genuine leather, such as PVC leather and PU leather, as artificial leather or anti-leather. Both PVC leather and PU leather are polyvinyl chloride (a type of plastic), but the production processes of these two types of leather are different.
In the production process of PVC leather, the recycled plastic must be melted and mixed into a thick state, and the required thickness is evenly coated on the T/C knitted fabric base, and then it is put into the polyurethane foaming furnace for polyurethane foaming, so that it has the softness that can adapt to the production and processing of various different leathers and different requirements. At the same time, it is surface treated (dyeing, embossing, polishing, matting, grinding and raising, etc., mainly according to the actual leather requirements).
PU leather is more complicated in the production process than PVC leather. Since the base fabric of PU leather is a canvas PU leather material with good compressive 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 base fabric cannot be seen from the outside. The physical properties of PU leather are better than those of PVC leather. It is resistant to bending, soft, strong and breathable (PVC leather does not have it).
The texture of PVC leather is formed by pressing a steel texture roller; the texture of PU leather is first pressed on the surface of the semi-finished leather with a kind of pattern paper, and then the paper leather is separated after cooling and surface treatment. The price of PU leather is several times higher than that of PVC leather. The price of some rigid PU leather is 2-3 times higher than that of PVC leather.
Generally, the pattern paper used for PU leather can only be used 4-5 times before it is depreciated; the service life of the texture roller is long, so the cost of PU leather is higher than that of PVC leather.
