Difference between aviation leather and genuine leather
1. Different sources of materials
Aviation leather is a kind of artificial leather made of high-tech synthetic materials. It is basically synthesized from multiple layers of polymers and has good waterproofness and wear resistance. Genuine leather refers to leather products processed from animal skin.
2. Different production processes
Aviation leather is made through a special chemical synthesis process, and its processing process and material selection are very delicate. Genuine leather is made through a series of complex processes such as collection, layering, and tanning. Genuine leather needs to remove excess substances such as hair and sebum during the production process, and finally forms leather after drying, swelling, stretching, wiping, etc.
3. Different uses
Aviation leather is a functional material, commonly used in the interiors of aircraft, cars, ships and other means of transportation, and the fabrics of furniture such as chairs and sofas. Due to its waterproof, anti-fouling, wear-resistant, and easy-to-clean characteristics, it is increasingly valued by people. Genuine leather is a high-end fashion material, commonly used in clothing, footwear, luggage and other fields. Because genuine leather has a natural texture and skin layering, it has a high ornamental value and fashion sense.
4. Different prices
Since the manufacturing process and material selection of aviation leather are relatively simple, the price is more affordable than genuine leather. Genuine leather is a high-end fashion material, so the price is relatively expensive. The price has also become an important consideration when people choose items.
In general, aviation leather and genuine leather are both high-quality materials. Although they are somewhat similar in appearance, there are great differences in material sources, manufacturing processes, uses and prices. When people make choices based on specific uses and needs, they should fully consider the above factors to choose the material that best suits them. -

Key indicators
1. Tear force. Tear force is a key indicator of leather for clothing, which basically reflects the durability of leather
2. Elongation under load. Elongation under load reflects the tensile properties of leather, usually the elongation under a specified load of 5N/mm2. For all leathers used for clothing, the elongation under load should be between 25% and 60%.
3. Color fastness to rubbing. Color fastness to rubbing reflects the binding fastness of dyes in leather, and is usually tested by 50 dry rubbings and 10 wet rubbings under a specified load. For all leathers used for clothing, the dry rubbing fastness should be greater than or equal to level 3/4, and the wet rubbing fastness should be greater than or equal to level 3.
4. Safety performance. The safety performance of leather mainly involves environmental safety indicators such as heavy metals, hexavalent chromium, formaldehyde, and banned aromatic amine dyes.
Purchase tips
1. Manually check the quality of leather. Poor quality leather may have defects such as cracking, discoloration, and cracked surface. The following methods can be used to identify it when purchasing:
Cracking: Press the leather surface with one hand, stretch the leather surface with the other hand, and use the index finger to push upward from the inside of the leather. If the coating cracks, it is cracking.
Discoloration: Use a slightly damp white soft cloth to wipe the leather surface repeatedly for 5 to 10 times. If the white soft cloth is stained, it can be considered that the leather is discolored.
Cracked surface: Fold the smooth surface into four corners and press it hard with your hands. If cracks appear on the smooth surface, it can be considered as cracked surface.
2. Smell the odor. Genuine leather usually contains an easily detectable grease smell, but it should not have an irritating or rancid odor. If you personally think that the smell of the clothing is unacceptable, it is not suitable to buy it.
3. Choose well-known merchants and brands. Give priority to purchasing leather clothing in regular large shopping malls. Good merchants have strict control over the quality of goods purchased, and the quality of the clothing they sell is better guaranteed.
Give priority to buying products from well-known brands. Most brand companies have rich experience in clothing processing and standardized management, good production conditions and equipment, strict selection and quality control of raw materials, and especially no “fake” products.
4. Check the label. Carefully check the factory name, address, trademark, specifications, material type, textile composition and content, implementation standards, and certificate of conformity on the label. -
Recycled Faux Leather Waterproof Embossed Synthetic Vegan PU Leather for Bags Sofas Other Accessories
Characteristics of pu materials, the difference between pu materials, pu leather and natural leather, PU fabric is a simulated leather fabric, synthesized from artificial materials, with the texture of genuine leather, very strong and durable, and inexpensive. People often say PU leather is a kind of leather material, such as PVC leather, Italian leather bran paper, recycled leather, etc. The manufacturing process is slightly complicated. Because the PU base fabric has good tensile strength, in addition to being coated on the base fabric, the base fabric can also be included in it, so that the existence of the base fabric cannot be seen from the outside.
Characteristics of pu materials
1. Good physical properties, resistance to twists and turns, good softness, high tensile strength, and breathability. The pattern of PU fabric is first hot-pressed on the surface of semi-finished leather with a patterned paper, and then the paper leather is separated and surface treated after cooling down.
2. High air permeability, the temperature permeability can reach 8000-14000g/24h/cm2, high peeling strength, high water pressure resistance, it is an ideal material for the surface and bottom layer of waterproof and breathable clothing fabrics.
3. High price. The price of some PU fabrics with special requirements is 2-3 times higher than that of PVC fabrics. The pattern paper required for general PU fabrics can only be used 4-5 times before it is scrapped;
4. The service life of the pattern roller is long, so the cost of PU leather is higher than that of PVC leather.
The difference between PU materials, PU leather and natural leather:
1. Smell:
PU leather has no fur smell, only the smell of plastic. However, natural animal leather is different. It has a strong fur smell, and even after processing, it will have a strong smell.
2. Look at the pores
Natural leather can see patterns or pores, and you can use your fingernails to scrape it and see the erected animal fibers. Pu leather products cannot see pores or patterns. If you see obvious traces of artificial carving, it is PU material, so we can also distinguish it by looking.
3. Touch with your hands
Natural leather feels very good and elastic. However, the feel of PU leather is relatively poor. The feel of PU is like touching plastic, and the elasticity is extremely poor, so the difference between real and fake leather can be judged by bending leather products. -
