Artificial leather is the first to be invented for leather fabrics. It is made of PVC plus plasticizer and other additives. It has the advantages of cheap price, rich color 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. From the chemical structure, it is closer to the leather fabric. It does not use plasticizer to achieve soft properties, so it does not become hard and brittle. At the same time, it has the advantages of rich colors and various patterns, and the price is cheaper than leather fabric. So it is welcomed by consumers.
Another type is PU with leather. Generally, the reverse layer is the second layer of leather. The surface is coated with a layer of PU resin, so it is also called film cowhide. Its price is cheaper and its utilization rate is high. With the change of the process, it is also made into various grades, such as imported two-layer cowhide. Due to its unique craftsmanship, stable quality and novel varieties, it is the current high-grade leather, and its price and grade are no less than the top layer of leather. PU leather and leather bags have their own characteristics. PU bags have beautiful appearance, good care, low price, but not wearable and easy to break; leather is expensive, troublesome, but durable.
Cortical fabrics and PVC artificial leather, PU synthetic leather are distinguished by two methods: one is the softness and hardness of the leather, the leather is very soft, the pu is hard, so most of the pu is applied to leather shoes; the second is melted with burning The method is to distinguish the method by taking a small piece of fabric on the fire, the leather fabric will not melt, and 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 gasoline soaking. 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.
