Comparison of PVC artificial leather and PU artificial leather production process

　　Artificial leather, a plastic product similar to leather. It is made by rolling plastic film onto cotton cloth or by evenly coating synthetic resin containing plasticizer onto cotton cloth and then processing it. It is soft in nature and has various colors and patterns.

　　Artificial leather is a mixture of resin raw materials and other additives, after certain processing to obtain a material similar to natural leather. At present, the more widely used resin raw materials are PVC (PVC) and polyurethane (PU).

　　PVC leather in the manufacturing process should be the first plastic particles hot melt stirred into a paste, according to the specified thickness uniformly coated in the T / C knitted fabric backing, and then into the foaming furnace for foaming, so that it has to adapt to the production of a variety of different products, different requirements of the softness of the surface at the same time out of the furnace (dyeing, embossing, grinding, matting, grinding surface hair, etc., mainly in accordance with the requirements of the specific products to be (mainly according to the specific product requirements).

　　PU leather in the manufacturing process than PVC leather is more complex, because the PU backing cloth is good tensile strength canvas PU material, in addition to coating on the top of the backing cloth, but also the backing cloth is contained in the middle, so that outside the view does not exist in the bottom of the cloth.PU leather's physical properties than the PVC leather is better, resistance to zigzagging, softness, good tensile strength, breathable (PVC does not have).
