Consumers generally refer to synthetic leather other than genuine leather such as PVC and PU leather as artificial leather or imitation leather, but the two products have different processes. To

In the manufacturing process, the PVC leather must first melt the plastic particles into a paste, and evenly coat it on the T/C knitted fabric base according to the specified thickness, and then enter the foaming furnace for foaming to make it suitable To produce a variety of different products with different softness requirements, surface treatment, dyeing, embossing, polishing, matting, polishing, fuzzing, etc. are carried out at the same time as the furnace, mainly according to the specific product requirements. To

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, it can be coated on top of the base fabric, and the base fabric can also be included in the middle to make it From the outside, it does not exist in the bottom cloth. PU leather has better physical properties than PVC leather, resistance to folding, good softness, high tensile strength, breathability, and no PVC. The pattern of PVC leather is formed by hot pressing with steel pattern rollers. The pattern of PU leather is made of a pattern paper, which is first hot pressed on the surface of the semi-finished leather, and after cooling down, the semi-finished leather is separated from the paper, and then the surface treatment is performed. The price of PU leather is more than double that of PVC leather. The price of some special requirements of PU leather is 2~3 times higher than that of PVC leather. Generally, the pattern paper required by PU leather can only be used 4 to 5 times before being scrapped. The pattern roller has a long service life, so the cost of PU leather is higher than that of PVC leather. To

There are also certain differences in the scope of application of these two materials. In terms of footwear, PVC leather is mostly used in linings or non-weight bearing parts, or to make children's shoes; PU leather can be applied to footwear fabrics or weight bearing parts . In terms of bags, PVC leather is more commonly used. This is because the items in the bag are different from the feet in the shoes, and will not emit heat and do not have to bear the weight of the person. PU leather and PVC leather are easy to distinguish. From the corners, the PU base fabric is much thicker than PVC, and the hand feel is different. PU has a softer hand and PVC has a harder hand. It can also be identified by fire. PU The smell of PVC is much lighter than that of PVC.
