Artificial leather is the first invented for cortical fabric substitutes, which is made of PVC plus plasticizers and other additives rolled composite made on the cloth, the advantage is cheap, rich colors, patterns, the disadvantage is easy to harden, Brittle. PU synthetic leather is used to replace PVC artificial leather, its price is higher than PVC artificial leather. From the chemical structure, it is closer to the cortical fabric, it does not use plasticizers to achieve the soft nature, so it will not harden, brittle, but also has a rich color, the advantages of many patterns, the price is cheaper than the cortex fabric, So by the consumer's welcome.
Another is the PU with leather, the general is the opposite of the second layer of leather leather, coated with a layer of PU resin on the surface, it is also known as filming leather. Its cheaper prices, high utilization. With the process changes made into a variety of grades of species, such as the import of two layers of leather, due to unique technology, quality and variety of novel features such as the current high-grade leather, the price and grade are no less than the first layer of leather. PU leather and leather bags have their own characteristics, PU purses look beautiful, good care, the price is lower, but not wear-resistant, easy to break; leather expensive, trouble-solving, but durable.
Cortical fabrics and PVC leather, PU synthetic leather in two ways to distinguish: First, the degree of soft leather, the leather is very soft, pu is hard, so most of the pu are used in leather shoes; the second is to melt the combustion Method to distinguish the method is to take a small piece of fabric on the fire, cortical fabric will not melt, and PVC artificial leather, PU synthetic leather will melt.
The difference between PVC artificial leather and PU synthetic leather can be distinguished by the method of gasoline immersion by using a small piece of fabric on gasoline for half an hour and then removing it. If it is PVC artificial leather, it will harden and become brittle, and if it is PU synthetic leather, it will not harden, brittle.
