What is the difference between pu and pvc fabrics

Most people will collectively call synthetic leather other than genuine leather such as PVC and PU leather fabrics artificial leather or imitation leather. Both PVC and PU are polyvinyl chloride (a type of plastic), but the manufacturing process of these two products is not the same.

In the manufacturing process of PVC leather, the plastic particles should be hot-melted and stirred into a paste, and evenly coated on the T/C knitted fabric base according to the specified thickness, and then foamed in a foaming furnace to make it adaptable. Produce a variety of different products with different requirements of softness, and carry out surface treatment (dyeing, embossing, polishing, matting, and fluffing on the polished surface, etc., mainly according to specific product requirements) when they are out of the oven.

The manufacturing process of PU leather fabric 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 base fabric, the base fabric can also be included in the middle, so that The existence of the bottom cloth cannot be seen from outside. The physical properties of PU leather fabrics are better than those of PVC leather, with resistance to twists and turns, good softness, high tensile strength, and breathability (PVC does not). The pattern of PVC leather is made by hot pressing with steel pattern roller; the pattern of PU leather is hot-pressed on the surface of semi-finished leather with a kind of pattern paper, and then the paper leather is separated after cooling down to make the surface. deal with. The price of PU leather is more than double that of PVC leather, and the price of PU leather with some special requirements is 2-3 times higher than that of PVC leather. Generally, the patterned paper required by PU leather can only be used for 4-5 times, and it will be scrapped; the service life of the patterned roller is long, so the cost of PU leather is higher than that of PVC leather.
