Most people will call synthetic leather other than genuine leather such as: PU Leather Substrate Fabric, PVC Leather Substrate Fabricv collectively referred to as artificial leather or imitation leather. PU Leather Substrate Fabric and PVC Leather Substrate Fabricv are both polyvinyl chloride (a type of plastic), but the manufacturing processes of these two products are different.

In the manufacturing process of PVC Leather Substrate Fabricv, the plastic particles should be hot-melted and stirred into a paste, uniformly coated on the T/C knitted fabric substrate according to the specified thickness, and then entered into the foaming furnace for foaming to make it have It can adapt to the production of various products with different requirements for softness, and can be surface treated (dyeing, embossing, polishing, matting, grinding and fluffing, etc., mainly in accordance with specific product requirements) when it is released.

The manufacturing process of PU Leather Substrate Fabric is more complicated than that of PVC Leather Substrate Fabric. Since PU Leather Substrate Fabric is a canvas PU material with good tensile strength, in addition to being coated on top of the base fabric, the base fabric can also be included in the fabric. In the middle, the existence of the base cloth is invisible from the outside. The physical properties of PU Leather Substrate Fabric are better than that of PVC leather. The pattern of PVC Leather Substrate Fabric is made by hot pressing with steel pattern rollers; the pattern of PU Leather Substrate Fabric is first hot-pressed on the surface of semi-finished leather with a patterned paper, and then the paper leather is processed after cooling down. Separate, do surface treatment. The price of PU leather is more than double that of PVC leather, and the price of PU Leather Substrate Fabric for some special requirements is 2-3 times higher than that of PVC Leather Substrate Fabric. Generally, the pattern paper required by PU Leather Substrate Fabric can only be used for 4-5 times, and it will be scrapped; the service cycle of the pattern roller is long, so the cost of PU Leather Substrate Fabric is higher than that of PVC Leather Substrate Fabric.
