Popular science knowledge of car seat materials

Car seat material is a configuration that many people attach great importance to when buying a car. The grade of its materials also determines the grade of the car to some extent. Moreover, the feel of leather seats is better than fabric seats. They are more comfortable to ride and easier to clean. However, when selling cars, many sellers will claim that their car seats are "leather seats". Even for some models that sell less than 100000, sales will casually say that their car is equipped with leather seats. In fact, just think about it. Where are so many leather seats! It's impossible. In fact, the types of car seats are very diverse. Only some very high-end leather materials meet the standard of leather. Today, Xiaobian will give you some popular science.
One of the leather seat materials: artificial leather. This can be said to be the main force of leather materials for models below 200000. It is generally divided into three types: PVC artificial leather with PVC resin as raw material, PU leather with PU resin as raw material, and synthetic leather with PU resin and non-woven fabric as raw material. Most of the artificial leather seats on the market today are made of PU polyurethane. The biggest advantage is low cost and durability. The function and practicability of some artificial leather are even no worse than that of leather.
Leather seat material 2: super fiber leather. This is a kind of relatively advanced artificial leather, fully called Microfiber Reinforced leather. It is a composite of polyurethane, but it is very close to leather in hand feel. Moreover, it is resistant to low temperature, wear and tear, and is not easy to crack. More importantly, it will not have any pollution from production to use, and has superior environmental protection performance. Therefore, it is also widely used in medium and high-grade models.
Leather seat material 3: leather. What we are talking about here is genuine leather. Today's leather is a general term for natural leather. In short, it is the leather material made from the skin peeled from animals after a series of physical, mechanical and chemical treatments. Leather is usually said to be durable, not easy to rot and damage. There are many kinds of leather. Different animal leather materials have great differences in processing technology. There are many grades in quality, grade and price atmosphere. The most used in cars are the first layer of cow leather or the second layer of cow leather. For a full leather seat, the cost of bare leather materials is at least thousands or even tens of thousands. Therefore, the real leather will only appear in luxury brand models. The leather materials of some medium and high-end models will not use 100% complete leather, but will grind the leather residue and leather fiber, and make recycled leather bonded with adhesive under high pressure, or use leather in some places that are often in contact with the interior and seats, and artificial leather in other parts.
How can we distinguish genuine leather from ordinary artificial leather? The simplest way is to look at the appearance, feel and smell. Generally, good leather has bright and soft color, soft and resilient feel, and no pungent taste; The second is smooth but hard to handle; Poor leather not only feels rough, but also has a strong plastic smell. In addition, after rubbing the leather, there will be a smell of the leather itself, while the super fiber leather does not have this smell.
