Application Of Leather Materials in Car Seats
Dec 12, 2021
This article mainly introduces several types of covering materials such as PVC leather, PVC abrasion-resistant leather, microfiber leather and real leather commonly used in seats, and a detailed comparison of these materials in terms of production process, internal structure, key performance and price, etc. analyze. The analysis results show that, as a new type of material, microfiber leather has obvious advantages in the comprehensive performance of automotive seats and has broad application prospects.
As an important part of the interior of a car, the seat is often developed as a core part in the initial stage of the vehicle development. The choice of leather covering material for the face cover not only affects the performance of the seat, but also determines the appearance level of the interior of the vehicle to a large extent. Therefore, the choice of leather material is very important to the design of the vehicle. With the development of science and technology, artificial leather has gone through the stages of PVC artificial leather, polyurethane artificial leather, polyurethane synthetic leather and polyurethane microfiber synthetic leather. At present, with the improvement of environmental protection requirements, customer requirements and cost-effectiveness, how to develop high-quality, low-cost, green and environmentally friendly products has become the focus of competition among major OEMs. This article compares and analyzes the production technology, physical properties, internal structure and price of several types of covering materials commonly used in seats.
Common seat covering leather material
1. PVC artificial leather
PVC artificial leather is the first seat covering material to be invented and applied. PVC artificial leather is also called PVC coated fabric, which is a material formed by mixing PVC powder, plasticizers and additives and coating them on the base fabric. The production process of PVC leather and PVC wear-resistant leather is similar, because the properties of the two materials are not the same, so the PVC dense layer and surface layer formula are slightly different. At present, the commonly used production processes of PVC artificial leather are calendering and coating.
2. Microfiber leather
Microfiber leather is a new material that has emerged with the development of textile technology. The surface layer of the microfiber leather is a thin layer of polyurethane, and the bottom layer is a substrate made of superfine fiber non-woven fabric impregnated with polyurethane. Microfiber leather not only has a structure similar to that of natural leather, but its appearance and touch are similar to those of natural leather, and it is difficult to distinguish the difference between the two in appearance. Therefore, microfiber leather is often used to replace real leather in car seats.

However, at present, due to the increase of vehicle consumer products and the relative lack of natural resources, the amount of leather used in economical vehicles is decreasing. This also gives a wide range of development opportunities for the new material of microfiber leather, which has a similar structure to real leather.
Comparative analysis of various materials
1. Production process comparison
The characteristics of the raw materials determine the production process of the material. The production processes of PVC leather, microfiber leather and real leather are completely different. The production process of PVC leather is simpler than that of microfiber leather and genuine leather, which is a factor that makes its price relatively cheap.
2. Material structure comparison
Microscopically, PVC leather is mainly composed of PVC dense layer, PVC foam layer and base fabric layer. PVC leather has a dense structure, and the appearance can achieve the effect of "simulation leather" as much as possible, but the air permeability is poor, and the ride comfort is worse than that of microfiber leather and real leather.
The microfiber leather is mainly composed of a base layer made of ultrafine fiber non-woven fabric impregnated with polyurethane resin and a dry-coated polyurethane surface layer. Because the microfiber non-woven fabric itself has a large porosity, it still retains a certain porosity after being impregnated with polyurethane. It can not only achieve the leather effect in appearance, but also close to leather in structure. It has better riding comfort than PVC leather and is equivalent to leather. The dermis is made of raw animal skin, and there is also a porous structure inside, and the dermis material has good air permeability.
