The accomplishment of using super leather and a synthetic cockpit cladding material.
●? Leather is not the darling of the new era.
How do you feel when you see the van carrying skins open the door in the documentary, and bloody skins gush out, accompanied by the smell of corruption? Do you think it's cruel to make handicrafts from animal skins?
In the automobile industry, the main source of leather covering fabrics for automobiles is cattle and sheep skins. The main source of these leather materials is the slaughterhouse that supplies us with meat. For slaughterhouses, leather as a by-product has very high economic value, so it is necessary to make full use of it. Because these cattle and sheep are farmed artificially, it should be said that using their skins as leather fabrics is the best use, which is essentially different from killing rare animals as luxury accessories.
The reason is mainly driven by the improvement of production efficiency and the reduction of manufacturing cost. Compared with the highly automated manufacturing process of synthetic fabrics, the manufacturing process of leather fabrics is complex and the efficiency is relatively low. At the same time, the larger the coating area, the higher the quality requirements of leather, resulting in a sharp increase in manufacturing costs. As an industrial product, synthetic fiber fabric has good product consistency control, which is one of its outstanding advantages. It is believed that with the progress of human civilization and synthetic coated fabrics, there will be fewer and fewer cases of using animal skins as automobile interiors.
●? You don't have to use genuine leather to present luxury.
In the past, due to complex processing technology, unique natural texture and soft touch, leather fabrics have become the darling of luxury car interior covering fabrics.
Undeniably, at present, synthetic fabrics can't get rid of the sense of reproduction of industrial products, and it is difficult to realize the unique texture of leather fabrics. But in addition, the synthetic fabric has completely surpassed the real leather in pollution resistance, wear resistance, processability, air permeability, cleaning convenience and portability. More importantly, the recyclable percentage of these synthetic fabrics is quite high, which can meet the needs of sustainable development in the future, which leather fabrics can't do.
●? Chuanqi GS4 cockpit's covering fabrics.
The guide price range of Chuanqi GS4 is 8.98-15.180,000. Obviously, the limited manufacturing cost can't make the expensive leather fabric on this car, and the leather fabric doesn't meet the younger positioning of this car.
◆? Japan Toray Super Soft Fabric
Lexus, Acura, and British finidi models all use the same manufacturing technology and materials of Ultrasuede fabric. This kind of fabric has the characteristics of soft touch, rich colors, high durability, good air permeability, warm in winter and cool in summer, easy to handle, light and smooth, easy to cut and so on.
You may not know much about Ultrasuede fabric, but you may be more familiar with Alcantara fabric. These two kinds of fabrics belong to the product sequence of Toray, Japan, which are similar to suede in texture and have certain differences in hand feel.
It is worth mentioning that Dongli adopted the technology of extracting polyester from sugarcane and polyurethane from castor oil. Polyester and polyurethane are important raw materials for superfine fabrics.
◆? European Benec-Carico PVC fabric
In addition to the striking Ultrasuede fabric, the seat of Chuanqi GS4 adopts the artificial PVC (polyvinyl chloride) fabric of German continental group BENECKE-KALIKO.
According to the engineer of Guangzhou Automobile Research Institute, this kind of fabric has a low score in perception and touch, and will be brushed off in the benchmarking evaluation process, and even Chuanqi's material selection library will not enter, let alone appear on Chuanqi's production models.
◆? Environmental protection TPO fabric
TPO fabric is directly bonded with molten plastic during the injection molding of the center console frame, which avoids the use of adhesive and reduces the generation of volatile harmful gases. Moreover, this TPO material can be completely recycled, which is nontoxic, harmless and pollution-free. At the same time, it has strong anti-ultraviolet ability and good processability, and has been widely used in automobile industry in recent years.
●? Can synthetic fabrics be harmful to human health?
Having said that, I wonder if you will have such doubts. Synthetic fabrics will release harmful gases, is it harmful to human health? The answer is-it depends. If automobile manufacturers do not strictly control the materials used to make automobile interiors, there will be a great probability of worrying cabin air quality. But if manufacturers have a set of strict standards and management methods, the situation will be very different.
At present, domestic automobile manufacturers follow a set of national recommended standards, namely "Guide to Indoor Air Quality Assessment of Passenger Cars" (GB/T27630-20 1 1), and 20 16 1 updated the relevant indicators (revised draft) of the standard, mainly in terms of pollutant limitation. But at present, this standard is only a recommendation standard, not a mandatory standard, so the binding force on automobile manufacturers is actually limited.
Chuanqi GS4 high indoor air quality standards need technical endorsement. There is VOC laboratory of Guangzhou Automobile Research Institute behind Chuanqi brand. The work of this laboratory is to ensure the air quality of the passenger compartment with a comprehensive subjective and objective evaluation system.
In order to ensure the air quality in the car, GAC Chuanqi controls all aspects of the whole automobile production process to avoid the influence of rubber compound, parts packaging and environmental odor used in the production process on the air quality of the finished car cabin. Strict control of all aspects of automobile manufacturing and interior material selection is an important reason why the air quality in Chuanqi GS4 car can far exceed the national standard.
I smelled them one by one, and sure enough, the cloth in one jar smelled of plastic, which made people very uncomfortable. And another jar containing cloth that emits harmful gases, I opened it and smelled it, but I couldn't smell anything. According to the researchers, this is because the cloth emits volatile and harmful gases, which are easy to volatilize after opening the jar, and ordinary people are not easy to detect.
It can be seen that in order to ensure that the air quality in the cockpit smells good, and in fact it is really good (volatile harmful gases may be colorless and tasteless), the Golden Nose team and VOC laboratory need to cooperate with each other in a series of experiments to create the exclusive cockpit odor atmosphere DNA of GAC Chuanqi.
●? Full text summary:
Will the cockpit made of synthetic fiber fabric affect passengers' health? There is no clear answer to this. This depends on whether the manufacturer has the corresponding detection ability and strict control measures for the air quality inside the car. China's national standards for indoor air quality are recommended standards and have limited binding force on manufacturers. Whether we can create a healthy cockpit for users is a test of manufacturers' conscience. For GAC Chuanqi, the concept of building a car is that the health of users is always the first. Compared with some manufacturers' concealment of data, I can feel their confidence and confidence from GAC Chuanqi's initiative to display the internal air quality data of new cars (Figure/Text/Figure/car home?
