What kinds of artificial leather are there?
2021-08-21
PVC and PU leather are collectively referred to as artificial leather or imitation leather. Both PVC and PU are polyvinyl chloride (a type of plastic), but the manufacturing processes of these two products are different.
In the manufacturing process of PVC leather, the plastic particles must be melted and stirred into a paste, uniformly coated on the T/C knitted fabric base according to the specified thickness, and then entered into the foaming furnace for foaming, so that it can adapt to Produce a variety of different products with different softness requirements, and carry out surface treatment (dying, embossing, polishing, matting, polishing, etc., mainly in accordance with specific product requirements) at the same time as the furnace.
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 The appearance can't be seen in the presence of the bottom cloth. The physical properties of PU leather are better than that of PVC leather. It is resistant to tortuosity, softness, tensile strength, and breathability (PVC does not). The pattern of PVC leather is formed by hot pressing with steel patterned rollers; the pattern of PU leather is pressed on the surface of semi-finished leather with a patterned paper first, and then the paper leather is separated to make the surface after cooling down. Processing. The price of PU leather is more than double that of PVC leather, and the price of some special requirements of PU leather is 2-3 times higher than that of PVC leather. Generally, the pattern paper required for PU leather can only be used 4-5 times and then it is scrapped; the pattern roller has a long service life, so the cost of PU leather is higher than that of PVC leather.
The difference between PU and PVC is relatively easy. From the corners, the PU base fabric is much thicker than PVC, and the feel is different. PU has a softer feel; PVC has a harder feel; it can also be burned with fire. PU The smell is much lighter than that of PVC.

PU has better hand feeling, softness and high cost. PVC feels relatively poor, (even if it is soft, it feels dry and soft), and the cost is low.
