Talking with data： Is the super-sensitive leather car seat cushion really sunburned？
[Pacific Auto Network Supplies Channel]It is not difficult to imagine this scene: at noon in summer, when you get into the car, you will be burned by the insolated seat. Earlier, when Xiao Bian visited the forum, he found that some netizens had installed a car seat cushion called "Super Skin". It is said that this kind of seat cushion is "neither hot nor cold". Is it really so magical? Xiaobian will personally test it.
What is extrasensory skin?
Supersensitive skinIt is a composite material. It is breathable, non-slip, comfortable, durable and easy to clean. Super-sensitive leather is suitable for any model, and it is also a car seat cushion that is universal in all seasons and neither hot nor cold.
● Preparation before test
In order to measure the temperature rise performance of the car seat cushion made of this material at high temperature, we found two kinds of seat cushion materials: one is Five Blessingg Jinniu’s super-sensitive leather 3D seat cushion, and the other is ordinary leather.
We will speak with data in the test, so the test instruments we use this time include: 300W infrared lamp and hand-held infrared thermometer. The infrared lamp is formed by inserting a tungsten wire into an inflatable quartz tube. The tungsten wire generates heat and heats the gas in the quartz tube under the action of alternating voltage, thus generating infrared electromagnetic waves, which can be used for heating. The infrared thermometer can determine the surface temperature by measuring the infrared energy radiated by the target surface.
Then, we need to pay attention to a question here: Is the infrared lamp we used in the test equal to the sun’s rays? The wavelength of infrared lamp is different from that of infrared rays in sunlight, and the content of infrared lamp, Yuba lamp or other light sources is completely different from that of rays harmful to human body in sunlight. Using infrared lamp to do the test is only to simulate a heat source and let us feel the temperature rise of two different materials under the condition of the same heat source.
● heating speed: super sensitive leather < leather.
In order to make each data reading comparable, we mark the surfaces of the two materials separately before testing, and each time when reading with infrared thermometer, the testing point will be aligned with the marked position.
After turning on the infrared light for about 20 seconds, we first felt the temperature rise of the cushion materials on both sides with our hands, and the leather obviously felt more soup, but the temperature rise of the super-sensitive leather was not so obvious.
Next, we will continuously use the thermometer to read the temperature rise value. Surprisingly, under the irradiation of infrared light, the highest temperature can reach more than 90 degrees, which is a bit unexpected.
However, it should be noted that this data test is not in line with our daily car habits, because the temperature of the seats in the car is difficult to reach more than 90 degrees under the exposure at noon, so we only show that the temperature rise of super-sensitive leather is better than that of ordinary leather by infrared light irradiation. So in order to make the experiment more ideal, we moved two experimental products outdoors to see their temperature rise under the condition of midday exposure.
Description of test conditions: In the hot weather of 38, we test the temperature rise within one hour from 12 noon to 1 o’clock. At this time, the ground temperature is 42 degrees.
Summary:Regardless of outdoor exposure or infrared lamp test, except for the highest temperature, the test results all illustrate the same problem: after the temperature rises to a certain extent, the temperature value will not fluctuate too much. Basically, the temperature of super-sensitive leather is up to 49 when it is exposed to the sun outdoors, while the temperature of ordinary leather is up to 66, which is close to the real temperature. If it is placed in the car environment, the temperature may not be so high.
● Is this kind of cushion environmentally friendly?
It seems that the report that black heart cotton is hidden in the seat cushion has always been very common. Generally speaking, there are still many cases in China where materials are not sent for inspection.
Therefore, the easiest way to see if black cotton has been used in the seat cushion is to prove it by testing standards.
What is SGS report?SGS states the results or conclusions after inspection, testing, certification and appraisal in the report, but the inspection and certification are not based on SGS standards, but on international standards, local laws and regulations, customer requirements or special industry requirements. SGS is only a fair and rigorous third party, with rich experience, professional equipment and personnel to carry out various inspections or tests according to standards.
Relevant certification:
CCC certification:The full name of 3C certification is "Compulsory Product Certification System", which is a product conformity assessment system implemented by China government in accordance with laws and regulations to protect consumers’ personal safety and national security, strengthen product quality management.
CE certification:That is, it is limited to the basic safety requirements of products that do not endanger the safety of human beings, animals and goods, rather than the general quality requirements. The coordination instruction only stipulates the main requirements, and the general instruction requirements are standard tasks. Therefore, the accurate meaning is that the CE mark is a safety qualified mark rather than a quality qualified mark.
Summary:At present, there is no mandatory standard in the automobile seat cushion industry, and it is entirely necessary for manufacturers to exercise self-discipline. However, in terms of testing standards, it is also divided into national standards and European standards. Generally speaking, the index of European standard is stricter, and SGS belongs to European standard.
● What is the loading effect?
After testing the car seat cushion made of this material, we also experienced its installation effect. Take Jinniu, Five Blessingg as an example. This set of seat cushion adopts concave-convex design, and many places are designed with breathable holes, so it is more breathable.
● Summary
Different car cushions will give people different feelings, whether it is genuine leather or imitation leather, or fabric seats and super-leather seat covers, all of which have their own advantages and disadvantages. As far as extrasensory skin is concerned, its advantages are good thermal conductivity and softness and comfort. However, although the car seat cushion is made of the same material, there will be some differences, such as whether environmental protection materials are used, whether high-quality fillers (such as high-elastic sponges) are used, and how the stitch technology and ventilation design are, etc. These are the criteria for considering the quality of a set of seat cushions. However, the performance of this Five Blessingg Jinniu car seat cushion tested this time is still very satisfactory.
