PU leather artificial leather

Artificial leather is the earliest invented substitute for leather fabrics. It is made by calendering and compounding PVC with plasticizers and other additives on cloth. The advantages are low price, rich colors, and various patterns. The disadvantage is that it is easy to harden. Become brittle. PU synthetic leather is used to replace PVC artificial leather, and its price is higher than PVC artificial leather. In terms of chemical structure, it is closer to leather fabrics. It does not use plasticizers to achieve softness, so it will not become hard or brittle. At the same time, it has the advantages of rich colors and various patterns, and the price is cheaper than leather fabrics. So it is welcomed by consumers.

There is also PU leather. Generally, the reverse side is the second layer of cowhide, and the surface is coated with a layer of PU resin, so it is also called film cowhide. The price is relatively cheap and the utilization rate is high. With the change of craftsmanship, it is also made into various grades, such as imported two-layer cowhide. Because of its unique craftsmanship, stable quality, and novel varieties, it is high-grade leather, and the price and grade are no less than the first-layer leather. PU leather and leather bags have their own characteristics. PU leather bags are beautiful in appearance, easy to handle, and low in price, but they are not wear-resistant and easy to break; leather is expensive, troublesome to care, but durable.

Leather fabrics are distinguished from PVC artificial leather and PU synthetic leather in two ways: one is the softness and hardness of the leather, the leather is very soft, and the pu is hard, so most of the pu is used in leather shoes; the second is melting by burning The method is different. The method is to take a small piece of fabric and put it on the fire. The leather fabric will not melt, while the PVC artificial leather and PU synthetic leather will melt.

The difference between PVC artificial leather and PU synthetic leather can be distinguished by the method of soaking in gasoline. The method is to use a small piece of fabric, put it in gasoline for half an hour, and then take it out. If it is PVC artificial leather, it will become hard and brittle. PU synthetic leather will not become hard and brittle.
