PU fabric is a simulated leather fabric, which is synthesized from artificial materials. It has the texture of real leather, is very strong and durable, and is cheap. The PU leather that people often talk about is a kind of leather, such as PVC leather, Italian leather bran paper, recycled leather, etc. The manufacturing process is slightly complicated. Since the PU base fabric has good tensile strength, in addition to being able to be coated on the base On the cloth, the base fabric can also be included so that the existence of the base fabric cannot be seen from the outside.
Characteristics of pu material
1. Good physical properties, resistance to bending, good softness, high tensile strength, Breathable. The pattern of the PU fabric is first hot-pressed on the surface of the semi-finished leather with a pattern paper, and then the paper leather is separated and surface treated after it cools down.
2. High air permeability, the temperature permeability can reach 8000-14000g/24h/cm2, high peel strength, high water pressure resistance, it is the top layer and bottom layer of waterproof and breathable clothing fabrics ideal material.
3. The price is high. The price of PU fabrics with certain special requirements is 2-3 times higher than PVC fabrics. Generally, the pattern paper required for PU fabrics can only be used 4-5 times before being scrapped;
4. The pattern roller has a long service life, so the cost of PU leather is higher than that of PVC leather. is high.
The difference between Pu material, PU leather and natural leather:
PU leather does not smell like fur, it just smells like plastic. However, natural animal leather is different. It has a strong smell of fur, even after treatment.
2. Look at the pores
You can see patterns or pores in natural leather, and you can scrape it with your fingernails , you can see the raised animal fibers. There are no pores or patterns on PU leather products. If you see obvious traces of artificial carving, it is PU material, so we can also identify it by looking.
3. Touch it with your hands
The feel of natural leather is very good and elastic. However, the feel of pu leather is relatively poor. The feel of pu is like touching plastic, and its elasticity is extremely poor. Therefore, the difference between genuine and fake leather can be determined by bending the leather products.
