How to distinguish artificial leather from genuine leather
Which is the better quality of artificial leather or genuine leather? Artificial leather should also be divided into many grades. There are also many kinds of leather, such as pigskin, cowhide and so on. The specific quality is good, judged according to their own needs. With the in-depth development of artificial leather technology, many artificial leathers can already be made very close to real leather, even for the purpose of fake leather. The editor of this article Standard Group will give you a brief introduction, cowhide It can be divided into multiple layers (up to 8 layers). The outermost layer is the first layer of leather, which has the best quality, followed by the second layer of leather. Its strength, elasticity and air permeability are not as good as that of the first layer of leather. The car seat must use the first layer of leather. One type of composite leather on the market now has a layer of glue on the surface of the second layer of leather. The surface is exquisite and looks a lot like the first layer of leather. Some businesses use this to pretend to be the first layer of leather to deceive users and should be identified. From a professional point of view, the identification of leather should be judged from the odor, specific gravity, light resistance, migration resistance, fogging, thermal yellowing, and friction resistance of automobile leather. Since most car owners do not have professional knowledge in this area, it is difficult to judge, so the following simple methods may be used for identification. 1. The labeling method of the leather factory will indicate the date of manufacture, the name and area of u200bu200bthe leather factory, etc. on the back. Of course, the manufacturing date should not be too long, and the leather that is more than 3 years old should pay attention to whether there is mold. 2. Leather with a good sense of smell should not have a pungent smell after treatment, so too much solvent and paint smell is not good. 3. For the heat-resistant method, it is best to ask the manufacturer for a small piece of leather, and use a cigarette end to touch the sample for about 2 to 3 seconds to avoid buying artificial leather products; burning with a lighter due to the large contact area, so the time needs to be extended. 4. Viewing method under a magnifying glass of 30 times, it can be seen that the leather outside is like the surface of the earth, with potholes and holes, and its air permeability is good. Automobile leather needs special treatment such as abrasion resistance and light resistance, and the pores will be covered. 5. The cutting method uses a blade to cross-cut the leather. The color of the leather from the outer surface to the inner layer must be the same (black on the outside and dark gray on the inside is normal). Pay attention to whether there are different colors under the outer surface layer, so as to avoid buying second-hand leather that has been dyed or changed color. 6. Wipe method Use scouring oil to wipe the surface of the leather, pay attention to whether there is any fading and falling off, which can avoid buying secondary color-changing leather. 7. Origin law All countries in the world produce leather, but the leather industry in Europe (Northern Europe, Italy, Austria, Germany, etc.) has a long history. Naturally, its leather processing level is much higher than that of low-end Southeast Asian leather. 8. The leather of the certificate law factory has a clear source, place of production, trademark, leather measurement items, leather use authorization and other basic information. 9. Guarantee method This is the easiest way. When buying leather chairs, don’t forget to ask the store if they have a guarantee service card. First, avoid buying inferior leather, second, develop a habit of regular maintenance, and third, provide permanent The after-sales maintenance service can be described as the benefits of three birds with one stone. 10. Recognize the leather by hand: touch the leather surface with your hand. If it feels smooth, soft, plump, and elastic, it is real leather; while the surface of general artificial synthetic leather is astringent, rigid, and has poor flexibility. At first sight: the real leather surface has clearer hairs and patterns, yellow leather has relatively well-proportioned fine pores, yak leather has coarser and sparse pores, and goat leather has scaly pores. Smell: All leather has the smell of leather; and artificial leather has a strong irritating smell of plastic. Ignite: Tear off a little fiber from the back of real leather and artificial leather. After lighting, all that emits a pungent odor and lumps are artificial leather; all that emits a hair odor without hard lumps are genuine leather.
